变速恒频风力发电机组控制策略分析

Research on control strategy of VSCF wind generating set

通过分析变速恒频风力发电机组运行工况,构建低于额定风速时的转速控制环和高于额定风速时的功率控制环。转速控制环和功率控制环二者独立工作,很好满足了机组对系统控制功能的要求,仿真结果表明该控制策略可行。

By analysis of variable speed constant frequency wind generation process status; speed control loop and power control loop are constructed according to wind speed, Speed control loop and power control loop take effect independently, control function is realized. The system is simulated by MATLAB and the simulation result shows that control strategy is feasible.
