Parameter Identification of Drive System for Fixed-Speed Wind Power Generation Units
摘要
Abstract
A method to identify parameters of drive system for wind-exited fixed-speed wind power generation (FSWG) unit is proposed. Firstly, taking a single machine infinite bus system for example, the perturbed trajectory of wind-excited FSWG is simulated and simulation results show that in view of the faster dynamic response of electrical part of induction generator, the electrical part of FSWG can be approximately represented by quasi-steady-model to reduce the order of the model and the numbers of parameters to be identified. Secondly, by use of trajectory sensitivity, the identifiability of parameters of drive system model is analyzed. Based on particle swarm optimization (PSO) the parameter identification is performed, and the feasibility of the parameter identification method of drive system for FSWG is verified.关键词
