摘　　要：在研究风力发电控制技术中,变桨距控制因其特有的技术特点,常被用在大型风力发电机组中,以保证额定功率点以上输出功率的恒定和机组的安全运行。由于大型风力发电机组的非线性、时变、强耦合等特征,为进一步提高系统的稳定性,用加入单个神经元在线调整模糊控制查询表的变桨距控制算法;并用MATLAB软件对机组控制进行仿真。仿真结果表明,变桨距控制算法具有良好的静、动态特性,能较好地将功率限定在额定值附近。The adjustable pitch control,because of its unique technical characteristics,is often applied on Large Scale Wind Turbine Generator System（WTGS） to ensure the constant output power above the rated power and the safe operation of WTGS.A new algorithm is designed,based on the analysis of principles of variable pitch control etc,to modify the Fuzzy Control Demand Table on-line through Single Neuron,according to the characteristics of multi-interference,time-varying and strong coupling.MATLAB software is applied to simulate the control effect of WTGS.The simulation results show that the proposed control algorithm has good static and dynamic performance and can limit the power at the vicinity of rated power.
