| 摘 要： | 针对某风电场双馈机组的现场高电压穿越测试中变流器故障导致风电机组脱网的问题，通过对风电机组变流器过压的深入分析，提出了一种风电机组在高电压穿越期间动态调整变流器母线参考电压的方法，解决了现场变流器过压保护导致风电机组脱网的问题。通过现场实测验证了所提策略的有效性，为风电机组的高电压穿越能力改造提供借鉴，为防范直流送端新能源电力系统的震荡提供了有益参考。

| Abstract: | Off-grid occurred in a wind farm caused by converter fault during field test of the DFIG (doubly feed induction generator) high voltage ride through (HVRT) capabilities. Through an in-depth analysis of the overvoltage of the wind turbine converter, a method was proposed for dynamic adjustment of converter DC bus reference voltage during wind turbine HVRT, which solved the off-grid problem of wind turbines caused by overvoltage protection of converter. Field test verified the effectiveness of the proposed method, which can provide useful experience for improving the wind turbine HVRT capabilities, and a reference for preventing the oscillation of renewable energy DC sending-end power system. |
