Abstract
The objective of this work is to validate wind turbine models available in commercial simulation tools with measurements. Results are shown for two turbines located in two different wind farms; wind turbine 1 is a fixed speed turbine with induction generator, and wind turbine 2 is a variable speed turbine with converter-interfaced synchronous generator. Simulated active and reactive power transient responses to voltage dips have been compared to measured responses, as suggested by IEA Wind Annex 21. For the fixed speed turbine quite good agreement between measurement and simulation is obtained. Shaft parameters are seen to have significant influence on the simulated active power response. For the variable speed turbine the active and reactive power responses are to a high degree determined by the power electronics interface and corresponding controllers, and particularly the control strategy applied during voltage dips. Wind turbine manufacturers are generally very restrictive on giving out this type of information, and thus typical configurations and parameters have been used in this work. The agreement between measurement and simulation can to some degree be improved by changing the inverter controller parameters by trialand error, but detailed knowledge on the control of the converter would be required in order to achieve a very good agreement.
