CLIENT: APA GROUP
LOCATION: Cervantes, WA.
SCOPE:
Prepare and verify a DIgSILENT PowerFactory dynamic model representing the 80MW Emu Downs site consisting of 48 Vestas Wind Turbine Generators (WTG), substation and interconnection to the 132kV grid.
TECHNICAL SITUATION
To build a dynamic model of the wind farm in PowerFactory APD used the following methodology:
- Prepare a steady state model to represent the 80MW wind farm site including WTGs, SVCs, cables, transformers, and 132/22kV substation;
- Add dynamic models of the wind turbines;
- Create a dynamic model of the SVC controller based upon manufacturer documentation
- Create a dynamic model of the park controller based upon manufacturer documentation;
- Perform simulations and compare results with those obtained from previous PSS/E simulations;
- Assist with the integration of the model into Western Power’s PowerFactory model of the South-West Interconnected System (SWIS);
- Revise the model according to on-site generator performance testing and evaluate the performance against Western Power’s Technical Rules.
SERVICES PROVIDED
- Steady state model build from drawings and equipment data sheets;
- Dynamic model build from manufacturer documentation;
- Perform simulations to evaluate wind farm’s performance and behaviour;
- Review information from generator testing and incorporate it into the model to refine behaviour;
- Liaise with the utility to integrate the wind farm model into their transmission network model.
