摘　　要：随着风电机组单机容量的不断增大,风电机组零部件承受的载荷越来越大,电网对机组输出功率的品质也提出了更高的要求。文章在变桨PID控制技术的基础上,通过增加塔架阻尼器、低通滤波器和陷波器,并在变桨时使用变增益双PID控制器,使风电机组在输出功率较为平滑的同时,降低关键部件的载荷。结合3 MW双馈式风电机组开发GH Bladed的外部控制器程序,并和广泛应用的PID控制器进行仿真比较。仿真结果表明,该研究提出的控制策略改善了风电机组输出功率的品质,降低了塔架等关键部件的载荷。As the growing of wind turbines equipped capacitor and the increasing of wind turbine unit capacity,the load of wind turbines and key components is becoming more and more heavy,and high power quality requirement is added to grid code. The pitch control strategy is optimized in the thesis through adding tower damper,low-pass filter and notch filter and variable gain double PID controller, the optimization aim is to smooth the generator output power and reduce the load of the key components. The optimized control strategy is carried out and simulated in the GH Bladed. A 3 MW doubly-fed wind turbines is taken as the control object in the simulation and results are compared. The simulation results indicate that, the proposed control strategy improved power quality and reduced the load of tower and other key components.
