Presentation overview

> Application of Hypersim at Hydro-Quebec, for both HIL testing and off-line simulation

• FACTS

• HVDC

• Wind Power

• Smart grid, Wide-Area Control Systems

• Specific Protection System and Protection relays


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


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


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


Application examples: FACTS testing

> Chenier Static Var Compensator (Quebec)

> Levis Synchronous Condenser (Quebec)

> Langlois Variable Frequency Transformer (Quebec-USA)


Application examples: HVDC testing

> Outaouais HVDC Interconnection, (Quebec-Ontario)

> Châteauguay HVDC Interconnection (Quebec-USA)

> Radisson-Nicolet-Boston Multi-terminal HVDC line

Comparaison of

simulation results vs field measurements


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.

> 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

Comparison at turbine level during a remote fault

«On-line monitoring» vs «EMT model»

Lessons learned…

«Various cases of disturbances and operating conditions must be used to increase the validity of the model»

WT: « Wind Turbine »

WPP: « Wind Power Plant »

1- Model Validation

> Results of «on-line monitoring» are used to fine-tune and validate…

• EMT model of WT

• EMT model of WPP

(non-public model)



«More than one equivalent WT is not

necessary for modeling a WPP when all

WT are exposed to the same wind speed»

Comparison of 4 different WPP models during a 2-phase fault. > The validity of the

«NREL equivalencing method» has been demonstrated

Lessons learned…

- a detailed WPP model with 73 WTs - a 1-, 2- and 4-WT equivalent WPP models
