摘要

永磁直驱风电系统机侧变流器的控制目标是在风速变化时，风电机组仍能实现最大风能追踪并保持稳定运行。通过建立风力机模型、永磁直驱同步发电机的数学模型，对零 d 轴控制法、单位功率因数控制法两种机侧变流器控制策略进行了理论对比分析，并通过仿真系统在风速恒定与变化情况下分别对两种控制策略进行了仿真验证，得到了单位功率因数控制法在过风速情况下风电机组更容易保持稳定运行的结论。

Abstract

The generator-side converter control aims to achieve maximum wind energy tracking and maintain stable operation despite changes in wind speed.In this paper

by establishing a wind turbine model and a mathematical model of the permanent magnet direct-drive(PMDD)synchronous generator

a theoretical comparative analysis of two generator-side converter control strategies

namely the zero d-axis control method and the unity power factor control method

is conducted.Moreover

simulation verification of the two control strategies under constant and varying wind speed conditions is performed using a simulation system.The conclusion is drawn that the unity power factor control method makes it easier for the wind turbine to maintain stable operation under overspeed conditions.
