Synchronization means the minimization of difference in voltage, frequency and phase angle between the corresponding phases of the generator output and grid supply. An alternating current generator must be synchronized with the grid prior to connection. It can’t deliver the power unless it is running at same frequency as the network.

In an alternating current electric power system, synchronization is the process of matching the speed and frequency of a generator or other source to a running network. An AC generator cannot deliver power to an electrical grid unless it is running at the same frequency as the network. There are several power generation units connected to the grid such as hydra, thermal, solar etc., to supply power to the load. These generating units need to supply power according to the rules of the grid. These rules involve maintaining a voltage variation within limits and also the frequency. If any deviation from the acceptable limit of the grid, it is mandatory that the same feeder should automatically get disconnected from the grid which by effect is termed as islanding. This prevents in large scale brown out or black out of the grid power. So, it is preferable to have a system which can warn the grid in advance so that alternate arrangements are kept on standby to avoid complete grid failure. In this paper hardware controller based system to identify the abnormalities and to disconnect the faulted part from the grid is proposed

This paper presents the development of a microcontroller based islanding detection for grid connected inverter with very simple under/over voltage and under/over frequency islanding detection algorithms. The microcontroller monitors the under/over voltage and under/over frequency from utility grid and the processed value of voltage and frequency for turning ON/OFF the relay between a grid connected inverter and the utility grid. The project would alternatively use a variable frequency generator using 555timer for changing the frequency while a standard variac shall be used to vary the input voltage for achieving the test conditions as stated above.

Abstract As the power grid failure problems continue to persist in the country, need arises to make it more efficient and effective. This is a demonstration devised to provide such kind of a system that could detect the failure in synchronous working of the power grid in case any external supply source that is supplying to the grid is encountering any kind of abnormalities may be in current levels, voltage levels, temperature and oil level. There are various generation units that usually supply power to the grids such as thermal plants, solar plants, hydro-electric plants etc. All the generation units that connect to the grid have to obey the rules or standards laid down for the operation of a grid. These rules involve maintaining of voltage variation, current variation, oil-level variation and temperature variation within these specified limits. If there are any kind of abnormalities or deviations from the acceptable limits laid down by the grid, it then gets crucial that the particular feeding source should get automatically disconnected from the entire grid temporarily, this process is widely termed islanding. This would prevent large scale occurrences of events of black outs. Hence it would be beneficial and wise if we could have a system that would be so efficient that it could issue intimations about the potential variations in the arrangements and in addition provide the exact distance of the fault location on a feeder line from the base grid and keep the particular source temporarily on a standby basis while this process takes place. Variation of the system voltage should be around +-5% as per central electricity authority of India Regulations, 2010. This paper is an approach on devising out a system that helps the grid resolve problems related to black out situations hence making it a smart grid. Keywords: - current variation, voltage variation, temperature variation, oil level detection, islanding, smart grid, active method, passive method.

The continuity of the electrical power supply is very important to consumers especially in the industrial sector. Protection relays are used in power systems to maximise continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilisation of the power. A good understanding of their application, operation and maintenance is critical for operating and maintenance personnel. In this workshop, you will gain a thorough understanding of the capabilities of power system protection relays and how they fit into the overall distribution network. The practical sessions covering the calculation of fault currents, selection of appropriate relays and relay coordination as well as hands-on practice in configuring and setting of some of the commonly used types of protection relays used in industry will give you an excellent understanding. Simulation software and real relays (but at safe voltages) will be used to give the participants practical experience in setting up and configuring the various power parameters. Both electro-mechanical and microprocessor relays will be used to demonstrate the key configuration settings required and the major differences in the approach adopted between these two classes of relays. The strengths and weaknesses of the latest microprocessor (or numerical) relays as compared to the older electromechanical relays will be outlined. You will also gain a solid appreciation of how the modern relay communicates not only to the central SCADA system but also between themselves resulting in a truly multifunctional system which includes protection, control and monitoring. Finally, you will gain a solid understanding of issues of reliability and security for the modern relay.
