Hydro-Québec’s Power
System:
Major Generating and
Transmission Facilities
> Hydro-Québec generates, transmits
and distributes electricity, mainly
using renewable energy sources, in
particular hydroelectricity.
> Installed capacity: 37 000 MW
> 15 interconnections with systems in
neighboring provinces and states.
> Very long transmission line with
series compensation. Numerous
FACTS devices.
> By 2015, HQ will be carrying about
4 000 MW of wind power over the
transmission system.

Wind Generation in Quebec
• Actually in service: ~2000 MW
• In service by 2015: ~4000 MW
Technical challenges
of wind power in the
gaspe peninsula
• Very low short-circuit
• Remote network with
no other generation
• Connected at Levis
substation with
series compensated lines
• Approx. 2000MW of
Wind Power from various
manufacturer and
technology (Type II-III-IV)

What is HYPERSIM ?
> HYPERSIM…
• Is a Real-Time Power System Simulator developed
by Hydro-Quebec for Electro-Magnetic Transient
(EMT)
• Is used by Hydro-Quebec for HIL testing of all
critical controls connected to its power system
– HVDCs, SVCs, Protection relays, PSS, etc…
• Is also used for off-line simulation, in complement
of traditional tools, for fast-simulation of complex
network…
– Example: Wind Power Plant detailed simulation

7. Groupe – Technologie7
HYPERSIM’s unique features ?
> HYPERSIM has been designed by power system
engineer for power system engineer…
• Automatic task mapping according to available processors
and I/O constraints
• The same simulation can be performed on a supercomputer
or any linux PC
• Great flexibility to integrate user-defined model into
simulation
– Simulink model, C-Coded model, DLL or «black-box» model

8. Groupe – Technologie9
The benefits of power system simulation
> Over the years, EMT simulation and real-time
HIL testing has proven to be very cost-effective
– Testing of Control and Protection
– Commissioning of interconnections
– Operating strategies
– Optimisation and settings
– Maintenance and training
– New concepts validation

11. Groupe – Technologie12
Application examples: Wind Power
> Hypersim is used for
1. Model Validation
2. Aggregation techniques of Wind Power Plant
3. Large-Scale Integration Studies (Real-time or Off-line)
« While traditional synchronous generation
modeling relies on physics,
Wind Generation modeling is all about controls…»
> Hypersim is the perfect tool for Wind Power integration
• Any user’s model can be integrated into simulation
– Simulink model, C-coded model, any DLL or «black-box»
model supplied by manufacturer
• Detailed simulation of Wind Power Plant with all turbines
represented can be achieved.

Application examples: Wind Power
> The ability to simulate Wind Power Plant with
all turbines represented brings unique
research opportunity
• Capability to evaluate
– the reliability of reduced/aggregated model
– Fault current contribution of WT/WPP
– Impact of individual control and protection
– Situation where only few turbines trip
• Research that are still under progress at HQ…
– Interaction with SSR, control interaction, resonance,
harmonic/inter-harmonic emissions, voltage flickers
– Operation strategies, inertial response
