Performing Acceptance Tests of a Wind Farm Power Plant Using the EMTP® Tool.

This presentation shows the acceptance tests performed on a wind power plant modeled using the WECC model. The plant cosistes of 121 turbines, each with a capacity of 0.85 MW, operating at 60 Hz. These turbines are connected to the 34.5 kV medium voltage collector system via 121 step-up transformers. The wind power plant is linked to the 320 kV network through a 230/34.5 kV 125 MVA main facility transformer. Other network components, such as collector cables and wind turbine step-up transformers, have also been represented by their equivalents. The model was developed and validated using two commercial tools – EMTP® and PSS®E. Simulations and analysis were performed to validate a group of acceptance tests required by the local utility. This presentation will focus on the modelling process, analysis and results obtained using EMTP®. The results obtained from the EMTP® and PSS®E are compared and discussed.
