摘　　要：构建了以鼠笼式感应电机为发电系统的大功率定速变桨距风力发电系统,实现了空气动力学子系统、机械传动链子系统、电磁子系统建模。以Matlab/Simulink为仿真研究工具,实现了各个子系统模块的设计,构建了鼠笼式感应发电机矢量控制系统,设计了转矩控制环、速度控制环和功率控制环的三闭环控制器,并完成了风力发电系统优化控制系统集成。仿真结果表明,该系统能实现大功率风能转换系统的最优控制特性跟踪,能有效解决已装机笼型感应风力发电系统的优化控制和系统改造。A high-power wind power generation system was constructed based on squirrel-cage induction generator （SCIG）. The mathematical models of the aerodynamics subsystem, the drive train subsystem, and the electromagnetic subsystenl were constructed. With the Matlah/Simulink platform, the SCIG vector control system was designed. The three closed contrail loop, namely, torque control loop, speed control loop, and power control loop） and the optimal eontrol system were integrated. Si,nulation results show this control system can realize optimal control of high-wind energy conversion system and can be effectively applied to the control and modification of SCIG wind power generation systems.
