- Thank you <name of moderator>. Good morning everyone…I’ve been with National Instruments for more than 14 years now and have had the opportunity to work with a lot of companies across Europe in various different fields such as automotive, aerospace and Energy. Having worked with various different companies I’m amazed to see how far we have come in engineering…much of what we have seen is because of the advancements in computer technology...and software has pretty much changed most of the industries we work with...modern cars are essentially a computer on wheels and air crafts fly by wire...latest technologies such as fast computer buses, high performance multi core processors and wireless communication also have a huge potential to help us dealing with some of the challenges in Energy.....that is what we are here for today.. To talk about how these technologies (SW and HW ) can be used to innovate and how you can gain access to them... Before I’ll talk more about some case studies and enabling technologies and products, I’d like to briefly introduce our company for those of you who are not familiar with what National Instruments does.
- …also known as the pioneer in Virtual Instrumentation which refers to the concept of using a multifunctional piece of HW that digitizes analog signals and graphical software to acquire – analyze – present (user defines the instrument) vs. a vendor-defined box instrument. We have had a strong track record in growth and profitability which has made us not only a reliable partner for our customers and suppliers but also has given us the opportunity to hire and work with very talented people which has been an important component of our strategy as a technology company.Although we are based out of Austin, TX, USA, we have become a truly multinational company with a majority of business happening outside the United Sates. In fact National Instruments employees > 1000 people in Central Eastern Europe…Also an important part of our strategy as technology and product company is the development of our Alliance Partner channel. They master our products and add domain expertise in various areas to provide you with turn key solutions. Some of which are here today and will present along with our customers on how our technology and products are used in Energy related applications.
- In his book “The Long Tail”, Chris Anderson describes that the relation between traditional products versus the grand variety all products in a market – partially disruptive or niche products - behaves like a 1/x function……This some what applies to the various energy sources as well…In the head of the tail we find our fossil fuels that globally provide a vast majority of the energy we consume. For those energy products we have an infrastructure in place. If we move down the tail along the x axis we find all possible energy sources that we started working with as well to ensure a sustainable energy supply as the demand for energy is increasing steeply.For us as engineers that brings along a number of tasks to solve in…
- Industry:Process Industries, Industrial Controls/ Devices/ SystemsProducts:CompactRIO, Compact FieldPoint, LabVIEW, FPGA ModuleThe Challenge:Developing an automation system for a steel recycling facility that reduces the amount of energy consumed to comply with statewide energy regulations while improving the safety and efficiency of the plant.The Solution:Using National Instruments programmable automation controllers (PACs) and the NI LabVIEW graphical programming environment to develop plant automation solutions to accurately measure the amount of energy required to recycle steel and improve facility safety."By programming with LabVIEW and PACs versus programming with PLCs and ladder logic, we have seen a ten-fold increase in efficiency and drastically reduced the costs of facility automation. "Reducing Energy Consumption with NI Software and HardwareAt the Marion facility we manufacture a full line of rebar, sign supports, delineators, and cable barrier systems using recycled steel. During the steel recycling process scrap metal is heated in an electric arc furnace (EAF) and, depending on the type of steel being produced, a combination of elements is added to the viscous steel to create the appropriate steel alloy. This process requires large amounts of energy that vary significantly depending on the amount of scrap placed in the furnace. When we purchased the Marion facility, operators relied on estimates to determine the amount of steel placed in the furnace, causing the metal to be overheated oftentimes. This results in an unsatisfactory end product that must be recycled again, which costs the company time, money, and energy.To reduce the number of reheats, we developed a low-cost scale and weighing system using LabVIEW and NI Compact FieldPoint controllers that accurately calculated the amount of steel in each burn. Knowing the exact amount of scrap metal placed in the furnace allowed us to precisely calculate the amount of electricity required to heat the furnace. Prior to implementing this scale system, our steel measuring was hit or miss. We did not have a method of tracking the number of reheats prior to implementation of the new system, however out of the more than 6,000 batches in 2007 after deploying the new system we only performed 10 reheats, which was far less than in 2006.Eliminating Flicker with LabVIEW and NI CompactRIOOne risk involved in drawing the large amount of electricity required to heat the furnace for recycling is causing flicker on the power grid. Not only did we receive monetary penalties for using too much electricity, but the power grid flicker was an inconvenience to Marion residents. To reduce electricity consumption, we developed an online reactor in series with the furnace using the LabVIEW FPGA module and the CompactRIO platform that measures the amount of energy drawn from the power grid. If the furnace approaches the prescribed limit, the system can quickly change control methods to reduce the amount of power being drawn.Improving Facility Safety with LabVIEWOne of our core values at Nucor is employee safety, thus another goal of our facility improvements was to make the Marion location a safer place to work. We determined we needed to upgrade the method for turning the EAF on and off. Before renovating the system, an operator had to manually pull the on/off switch, which made him or her vulnerable to injury if the fuse were to blow. A Compact FieldPoint PAC and an HMI were used to create a remote power switch that does not put operators in potentially dangerous situations.The Benefits of Factory Automation Using NI PACsUsing hardware and software from NI, we developed a variety of automation systems that have greatly reduced the electricity we use and eliminated potential safety issues at our Marion, Ohio facility. By programming with LabVIEW and PACs versus programming with PLCs and ladder logic, we have seen a ten-fold increase in efficiency and drastically reduced the costs of facility automation. Additionally, by developing a proactive approach for monitoring our power intake using the National Instruments platform, we have reduced the impact our facility has on the residents of Marion by eliminating power grid flicker.

- Industry:Industrial Controls/ Devices/ Systems, Oil and Gas, Machines/MechanicsProducts:Compact FieldPoint, LabVIEW PDA Module, LabVIEWThe Challenge:Developing a reliable mercury emissions sampling system to provide the control, calibration, and maintenance features required by stringent federal regulations for coal-fired power plants.The Solution:Creating a flexible, real-time software architecture deployed with an NI Compact FieldPoint Programmable Automation Controller (PAC) with a wireless communications interface on a PDA. The PDA provides all status displays and operator interactions. The system saves data to the CompactFlash drive and broadcasts data over an RS-485 serial connection to a data logger."The success of the project was due to the processing and automation power of the NI cFP-2120 and the ease of use derived from integrating the PDA control system."Creating a flexible, real-time software architecture deployed with an NI Compact FieldPoint Programmable Automation Controller (PAC) with a wireless communications interface on a PDA. The PDA provides all status displays and operator interactions. The system saves data to the CompactFlash drive and broadcasts data over an RS-485 serial connection to a data logger.To comply with federal clean air regulations, mercury emissions from coal-fired power plants must be continuously monitored. The proportional measurement technique requires sampling rates to be continually adjusted to remain in proportion to stack flow. In addition, all calibration, maintenance, and leak-checking modes must be automated. This system uses a PAC that operates remotely, controlling the sample collection for as long as a week. The only computer connection is an RS-485 output line to a data logger. Therefore, all control and programming of the PAC, as well as all user feedback, is through a wireless connection on a PDA running the NI LabVIEW PDA Module.Sampling ModeThe full system we built controls two sampling paths that consist of sampling pumps, leak-check valves, and proportional control valves operated by the pulse-width modulation Compact FieldPoint. Immediately after connecting to the Compact FieldPoint bank, we were able to test and troubleshoot all the hardware modules in the system. This allowed several design issues to be addressed early in the process before the LabVIEW programming became too specific.Data is collected at one-second intervals and each data collection is broadcast over a serial connection to a remote system. The data is averaged hourly. Hourly averages are saved to non-volatile memory and used to adjust set points for flow and temperature control. All data is compared with a series of alarm set points that raise system flags or stop sampling during the alarm. The system needs to have the ability to enter and return from a suspended function during an alarm. The integrated RS-485 connection on the NI cFP-2120 allows industrial serial communication, and the expanded memory of the CompactFlash slot enables long-tem data storage for the system.The control loops run simultaneously with the data collection, broadcasting, and analysis. A set of heaters is controlled by PID loops to keep the sampling ports at constant temperatures. Also, to maintain the sampling flow at a constant ratio to changing stack flow rate, each flow path is controlled by its own PID controller. Each of these loops references user-defined set points in conjunction with measured values to maintain flow and temperature at required values.PDA ConnectionThe remote location of the system and lack of network connection meant that the device would run “headless” with no computer connection. The deployed executable communicates with a rugged PDA through a shared variable library with the NI cFP-2120 as the shared variable server. The variables are network published and an 802.11 wireless Ethernet bridge connects the NI cFP-2120 Ethernet port to the wireless capability of the PDA. Both system commands and changes of program state are communicated through the PDA, which can also display and change system settings. Other than beginning the automated sampling mode described above, the PDA is used to operate several user-interactive modes.CalibrationThis mode checks all the built-in sensors of the system. The calibrations range in complexity from a simple comparison to a standard in the case of thermocouple calibration, to an intricate, controlled-flow check of the dry gas meters. All calibration data is stored locally on the PAC in a LabVIEW configuration file format,. The most recent calibration values are retrieved from these files to convert and scale raw values read from the Compact FieldPoint module in each sampling run.Leak CheckThis is another automated check of the system used before each sampling run to verify the integrity of the sample path. The values are checked before and after each test, and the user can interact with the device to accept or repeat tests as necessary.MaintenanceDuring maintenance mode, the user has full control of the system. This mode can turn all pumps and valves on and off and the current state or level of all the Compact FieldPoint channels. In this mode, the user-defined functional set points can be entered, read, or updated. During this mode the NI cFP-2120 system time is automatically synchronized with the PDA to prevent divergence of timestamp values.Data TransferThe 2 GB memory of the CompactFlash means several years of data can be stored on the system. For diagnostic procedures and record keeping, a transfer mechanism is set up to collect data files from the PAC to send to the PDA. The PDA connects to the Compact FieldPoint which then populates a list with all the existing .DAT or .CAL files, any of which can be selected and copied through TCP/IP protocol to local PDA memory. The system also prevents currently used and incomplete data files from transferring in the middle of a sampling run.The success of the project was due to the processing and automation power of the NI cFP-2120 and the ease of use derived from integrating the PDA control system. This streamlined the interface for the user while allowing the automated processes to take care of most of the sampling functions. Performance was enhanced by the NI cFP-2120 incorporation of Ethernet and serial communication. The CompactFlash expandable memory saved time by avoiding the need for additional hardware integration and troubleshooting.
- Certain type of application such as plasma control for fusion tokamaks require sophisticated math to be executed in real-time to be able to perform the control application. At National Instruments we call design of algorithms that the run on real-time systems connected to real data via I/O - for instance on small rugged autonomous platforms such as CompactRIO - Algorithm Engineering. In order to continue to facilitate this process we released a LabVIEW module that allows you to deploy m scripts to real-time platforms…
- At the heart of our control platforms we find an FPGA chip that connects to real-world (sensors and actuators). This chip is fully programmable with the LabVIEW Graphical Development. This allows for rapid prototyping of embedded systems in software. This technology is available on all of our platforms – ranging from commercial PCs, Industrial Computers to small rugged embedded platforms such as CompactRIO.
- NI promotes that you can use the same hardware and software platform to prototype, test, and then deploy high volume solutions. The biggest cost is not in creating ideas it’s verifying an ideas economic value that is expensive.
- The Challenge: Implementing a power quality analyzer that includes a set of instruments, capable of performing all necessary electric power measurements andable to run in parallel on a small size hardware system with a real-time operating system. We also had to take in consideration the expandabilityof the system to encompass the latest IEC and EN standards when design measurement and data processing algorithms. The Solution:A power quality analyzer that complies with international power quality standards and is built based upon COTS (Commercial-Off-The-Shelf) toolssuch as NI CompactRIO, a rugged and scalable hardware platform and NI LabVIEW graphical development environment. Firmware that featuresan instrument user interface and a remote command library to allow easy configuration of all data acquisition tasks as well as data processing andstorage. The stored data can be analyzed comfortably off-line and it can be used for report generation too. “The ENA power quality analyzer family can be modified or extended easily in a short period of time according tolatest international standards and/or any additional functionality required by the customer.”(Dr. Daniel Kaminsky, Director at ELCOM, a.s.) Why are Power Quality Measurements Important?Electricity is a product like any other and perhaps is the most essential raw material used by commerce and industry today. It is an unusual commoditybecause it is required as a continuous flow – it cannot be conveniently stored in quantity – and it cannot be subject to quality assurance checks beforeit is used. Electricity of poor quality, for example, can cause significant damages in production lines. Therefore, by monitoring power quality, it ispossible to identify potential problems before they are big enough to create damages that all too often come with serious fnancial losses. Prevention,however, is relatively cheap and ranges from simple best-practice-design-considerations to global installations of monitoring and control equipment. What Has to be Measured?A typical power quality analyzer analyses 3 voltages of power networkto calculate voltage quality defined in international standards. Voltagequality is described by frequency, voltage level variation, flicker, three phasesystem unbalance, harmonic spectra, total harmonic distortionand signaling voltages level. In some cases is necessary to analyzetogether with the voltages also the current signals. This allows analysisof current parameters and calculation of indirect quantities like activepower, reactive power, energies and other quantities.Our power quality analyzer software and hardware suite is namedENA (ELCOM Network Analyzer) and represents a complex modularsystem for power quality monitoring according to actual internationalstandards and other national-specific documents. Considerations for Choosing the Development Platform We chose to implement our system on the NI CompactRIO platform with C Series modules. In comparison to PC-based instruments, it ismore compact, rugged, and smaller in size 3.4 x 7 x 3.5” (88 x 180 x 90mm H x W x D). It also has better temperature specifications (operatingtemperature -40°C to +70°C) as well as very low power consumption (approximately 8W). Furthermore the NI CompactRIO product family offersvarious form factors which we believed was important to be able to accommodate different customer and application needs.From the variety of I/O modules we used the NI 9225 300V power measurement module for performing high-voltage measurements. The moduleis designed for measurements, such as line-to-neutral as well as line-to-line measurements of 110V power grids and line-to-neutral measurementsof 240V power grids. For current measurements we use NI 9227. The NI 9225 and NI 9227 have simultaneously sampled channels at 50 kS/sfor accurate three-phase power metering and power quality measurements such as flicker, harmonics and power factor. Alternatively we havedesigned voltage and current modules: EL9215U-R1 and EL9215I-R1 that are based on the NI 9215 module and use our signal conditioningelectronics. These are embedded in 3 slots of a CompactRIO chassis. As software development environment we have used National InstrumentsLabVIEW for all parts of ENA software as the ease of use, portability and scalability of the solution was also very important. There exist severalmodels of CompactRIO power quality analyzers which differ in CompactRIO models and the used input modules. ENA power quality analyzerfirmware minimum requirements are 400MHz processor controller and chassis with 2M Gate FPGA. The CompactRIO-based Power Quality Analyzer The model name that we present here is ENA450, but due to the scalability of NI CompactRIO product family, the system and the portability ofthe LabVIEW code, we were able to implement the system in different form factors to accommodate various different application and customerspecific needs. Besides the implementations based upon the fully flexible NI CompactRIO system (ENA450.EC), we have created turnkey solutionswhere we have deployed our application to:» Integrated CompactRIO systems that combine a real-time processor and a reconfigurable field-programmable gate array (FPGA) within thesame chassis (ENA450.EB, ENA450.NB)» to Single-Board RIO systems that integrate the three core components of an NI CompactRIO system – real-time processor, field-programmablegate array (FPGA), and I/O – on a single printed circuit board (ENA460).The analyzer capabilities are defined by instrument hardware and software. ENA power quality monitoring system contains a bundle of softwareapplications for analyzer remote control, stored data analysis and for presenting power quality data across the Internet. The modular conceptallows fulfilling all customer needs together with minimizing costs. Measurement Capabilities The firmware ENA-Node is running directly on the CompactRIO based ENA450 analyzer and provides a measurement service that handles alldata acquisition, calculations and storing.The ENA-Node contains several software modules running in parallel:» FFT analyzer» Vector analyzer» Power Flow monitor» Flicker meter» EN50160 Voltage monitor» Half-period RMS monitor» Voltage Telegrams & Alarms» Digital InputsAll mentioned firmware modules are suited for 50Hz and 60Hz power system. Users can observe data on the instrument display and store theminto the data files. All instruments are working with a sampling rate of 9.6kS/sec per channel. The sampling rate is synchronized with frequency ofmeasured signals. Implemented algorithms follow the requirements of the actual power quality standards like IEC61000-4-30, IEC61000-4-15, andIEC61000-4-7.The software analyses three voltage signals up to 300V rmsand three currents instant values of power network to calculatevarious quantities like: RMS values, frequency, harmonic spectra,total harmonic distortion, flicker, three-phase system unbalance,active power, reactive power, energies and many other quantities.Currents as outputs of current transformers (1A/5A) can bemeasured directly by using the NI 9227 current module or theELCOM EL9215I-R1 current module connected indirectly bycurrent clamps.Voltage Current Power Energy Voltage evaluatedaccording EN50160 RMS (200ms & half period) RMS (200ms & half period) Power factor Active energy total RMSTHD THD CosineActive energy fundamental(1st harmonic)THDHarmonic (1–50th) Harmonic (1–50th) Active power total Reactive energy total Harmonics (1–25th)Interharmonic (0.5–49.5th) Interharmonic (0.5–49.5th) Active power harmonic (1–50th)Reactive energy fundamental(1st harmonic)UnbalanceDC part DC Part Reactive power total Apparent energy total FrequencyUnbalanceReactive power harmonic(1–50th)Active energy positive Signaling voltagesShort time flicker Pst,long time flicker PltActive energy negativeApparent power total Reactive energy inductiveApparent power harmonic(1–50th)Reactive energy capacitive User Interface for Instrument Control, Data Management and Reporting The easy to use user interface ENA-Touch is a graphical user interface for the ENA measurement service. All instrument control, data presentationand measurement configurations are operated through this application. To display measured quantities it allows easy and well arranged configurationand measured data presentations. There are two types of visualization panels: some panels have fixed set of quantities in tables, and somepanels have user defined set of quantities to display while enabling numerous ways on how to present data: tables, frequency domain graphs,scope, vectorscope and statistical results for power quality. ENA-Touch user interface is optimized for control by touch screen display and canbe used also on Ultra Mobile PC with resolution 800x480. ENA-Touch can control ENA-Node remotely by using TCP/IP protocol over Ethernet.Simultaneously with all on-line data presentations, the system allows to store data for off-line analysis as well. The calculated quantities areaggregated in time, and some data are statistically evaluated before storing. The data is stored periodically with defined time intervals, whileevent-based data is stored just when the event appears.With ENA-Report stored data can be analyzed comfortably off-line and besides that it can be used for report generation too. Distributed Power Quality Monitoring with ENA Distributed monitoring systems can be built using several ENA450 analyzers. The data in the distributed system can be replicated to MS-SQL orORACLE database for central storage and off-line analysis. Conclusion The main advantage of the described power quality monitoring system is its high-performance, flexibility and small size. Using the C-Series moduleswith built-in signal conditioning, and implementing the powerful and user-friendly solution, dramatically simplifies the software maintenance andfurther development without impact on the current solution. In case of any updates or changes to the standards, the instrument features can beupdated quickly and the system stays up to date. Due to the open solution the existing system can be easily integrated with other systems, as thecommunication protocols can be adjusted in accordance with customer needs or integration into existing SCADA systems. The open hardwarearchitecture makes possible to add new DIO for monitoring and controlling as well as modules for wireless communication via GPS or GSM.The flexibility of NI CompactRIO and NI LabVIEW, allowed us also to implement a complete PMU analyzer (Phase Measurement Unit) in thematter of weeks. It allows precise evaluation of the synchrophasors in accordance with the IEEE C37.118-2005 standard. We are currentlyworking on integrating the PMU analyzer with the power quality analyzer, ENA450, into one single instrument.
