摘　　要：有别于以往的只通过电脑仿真软件进行低电压穿越能力验证,在东北地区风电场进行风机的LVRT实施能力测试。通过安装在风机690 V一侧的电网故障模拟器,测试单台风机的LVRT能力。通过人工制造电网故障环境,分析DFIG风机的动态表现,对风机的不同控制策略,如主动Crowbar、被动Crowbar和斩波器保护进行验证。为提高风电机组的LVRT能力,对有功功率和无功功率的补偿方法进行探讨。Being different from other paper which only do software simulation, this paper develops real field LVRT tests for wind tur- bines on Chinese Northeast wind farms. Wind turbine＇s voltage drop is realized through a voltage dip simulator located on the 690 V side. This means that different grid faults are made to test DFIG＇s LVRT ability and dynamic response. Active and passive crowbar schemes are verified. This paper also explores active and reactive power compensation methods.
