Benchmark Model of Type-III Wind Turbine for Research and Development Applications

Abstract

This paper presents average and detailed models for type-III wind turbines that can be utilized by researchers and engineers as a benchmark in their research and studies. Both models are developed in PSCAD/EMTDC and their dynamic behavior and computational time are compared against each other. The comparison is conducted for two different dynamic scenarios, fast transients in an event of a fault and slow wind speed variations. It is shown that the simulation results obtained from the average model are comparable to those of the detailed model in terms of accuracy while the simulation time is approximately 15 times faster. The sub-synchronous impedances of both models are calculated via simulation, and it is shown that impedance of the average model resembles the detailed one. Moreover, aggregation model of wind farms is shown, such that intensive computations can be eluded and simulation time can be saved.
