失速型风力发电机组双速电机切换过程的仿真分析

基于XWEC－JACOBS 43／600风力发电机组，利用Simulink仿真软件建立了双速电机的数学模型，对双速电机切换过程进行了仿真分析，确定了满足大电机到小电机优化切换的定子输出电流范围，为双速电机切换控制的系统实现提供了理论依据，也为今后针对双速电机切换的过程的最优控制器设计提供了理论参考。

SIMULATION ON THE TRANSFER PROCESS BETWEEN BIG AND SMALL GENERATOR IN STALL REGULATED WIND TURBINE GENERATOR

In this paper,the mathematic models for two speeds generator are established using Simulink based on stall regulated Jacobs 600kW Wind Turbine Generator.The simulation on transfer process between big and small generators is also presented.The range for stator current to ensure the optimal transfer form big to small generator is reached,which offers a theoretical basis for the system implementation of the transfer process in the electric control system and also gives useful informction to future work on the optimal controller design over such transfer process.
