摘　　要：在分析风电机组变桨距调节原理的基础上,建立了包含风力机、变桨距执行系统、变桨距控制算法、变桨速率、动态尾流、塔架动态、传感器响应的变桨距风电机组整体动态数学模型。以此为基础,运用MATLAB/SIMULINK仿真模拟平台搭建了变桨距风电机组动态仿真模型。以阵风为例,运用该模型对一台1.5MW的风电机组进行了变桨距过程动态特性仿真。仿真结果与简化模型仿真结果对比表明:建立的模型能很好地描述变桨距过程中的机械转矩过冲、桨距角滞后等动态特性,弥补了现有各种模型过于简化的不足。The regulative principle of Variable Pitch Wind Turbine Generator System（VPWTGS） is analyzed.A dynamic mathematical model which includes wind turbine, pitch executive facility, control algorithm,pitch rate, dynamic wake, tower dynamic and sensor responding to this system is built.Based on this, a dynamic simulation model is set up by using MATLAB/ SIMULINK simulation platform.The characteristic simulation of a 1.5 MW VPWTGS is calculated under gust wind speed.Simulation results, which are compared with those of simplified model, indicate that the proposed model can better describe the dynamic character of variable pitch process, and can make up for the over-simplifications of models in literatures.
