Generic Models for Type 3 and 4 Wind Turbine Generators Pouyan Pourbeik ppourbeik@epri.com WECC REMTF Meeting November, 2011

OVERALL MODEL STRUCTURE

ELECTRICAL CONTROLS

WT4 Most recent proposal [1] & [2]. Not very different from [3] and only a few changes compared to current WECC model. Used Data graciously provided under NDA from Vestas and Siemens Wind Power, respectively. Acknowledgements: Babak Badrzadeh, Vestas Nikolaus Moeller Goldenbaum, Siemens

THE MODEL P-CONTROL

THE MODEL OPTIONAL DRIVE-TRAIN

THE MODEL Q-CONTROL or

FIELD MEASURED DATA

RESULTS WITH SIEMENS WTG [2]

ASIDE (see [2] for details)

RESULTS WITH VESTAS WTG [1] Eight (8) cases studied

EXAMPLE CASES (RESULTS WITH VESTAS WTG [1])

EXAMPLE CASES (RESULTS WITH VESTAS WTG [1])

ABB CASES SHOWN PREVIOUSLY [4] STILL VALID WITH THIS MODEL Data provide by ABB under NDA to EPRI

CONCLUSION We believe that this model now caters to multiple vendor equipment, and has been shown to give good validation results Some minor conventions have to be discussed and finalized The “spike” issue need software resolution – several ideas are being pursued
