Dynamic multi-machine equivalent model of direct drive permanent magnet synchronous generators of wind farm
摘要
Abstract
In order to improve the efficiency of simulation, a dynamic multi-machine equivalent model suitable for the wind farm equipped with direct-driven permanent magnet synchronous generators (D-PMSG) is presented. Based on the homology equivalent method, the matrix of variables that can comprehensively reflect the wind generators’ operation state is adopted as cluster classification index. Then, the wind turbines with similar operating point are divided into the same group by processing the index matrix with fuzzy clustering algorithm. The wind generators are represented by an equivalent wind turbine through a wind generator paralleled with a current source. Therefore, the overall equivalent wind farm model can be assembled with multiple representative equivalent wind turbines. Case study is carried out on ATP/EMTP platform and simulation results prove the validity of the proposed model compared with corresponding detailed model.
