摘要：

以液压型风力发电机组作为研究对象,根据机组低电压穿越控制过程对液压系统功率快速调整的要求，以发电机稳定于工频转速和液压系统瞬态调整时间最短为控制目标，提出一种基于直接控制变量马达摆角的低电压穿越控制方法。以30kV·A液压型风力发电机组模拟实验台为仿真和实验平台，针对提出的低电压穿越控制方法展开研究，仿真和实验分析表明,直接控制变量马达摆角的方法具有较好的低电压穿越控制效果。

Abstract:

Taking a hydraulic wind turbine as the research object,a LVRT control method was proposed based on the direct control of the swing angle of the variable motor aiming at rapid adjustment of the hydraulic system power requirements. The control target was that the power frequency speed of generator was stabile and the hydraulic system transient adjustment time was short. Using 30kV·A hydraulic wind turbine simulation platform as the simulation and experimental platform, the control method presented for LVRT was researched. Simulation analysis and experimental results show that the LVRT control method based on the direct control of the swing angle of the variable motor has better low voltage ride control.

Key words: wind power generation;synchronous generator;hydraulic transmission;low voltage ride through(LVRT);direct control of , swing angle
