摘要

在分析变速变桨距风力发电机组基本控制策略的基础上，提出一种扩大过渡区的改进控制策略，用来消除额定功率运行点附近切换造成的功率波动及突变载荷等不利影响。依据改进的控制策略设计了3个控制器平滑过渡方案，实现对该策略的最佳跟踪。运用MATLAB仿真平台模拟了改进控制策略下的风力发电机组运行特性，结果表明了改进控制策略的正确性及控制器设计的有效性。

Abstract

Based on an analysis of basic control strategy for variable-speed pitch controlled wind turbine driven generator system， an improved control strategy of enlarging the transition region is proposed to mitigate the harmful effects caused by controller switch near the rated power point， such as power fluctuation and sudden load change. A three-controller smooth transition scheme is designed to fulfill the optimal tracking to the improved control strategy. The operation characteristics of the generator system with the improved control strategy are simulated on the MATLAB simulation platform， and the results prove the correctness and effectiveness of the improved control strategy.
