摘　　要：近期频繁发生的风电连锁脱网事故表明风电场集电系统的无功电压分布会对风电场的安全稳定运行产生很大的影响。首先介绍了风电场集电系统的概况,在此基础上分析了风电场集电系统的无功电压时空分布特性和风电功率波动对风电机组机端电压的影响。为风电场运行人员提供了运行的依据,保证了风电场的安全稳定运行,同时也为大规模风电连锁脱网事故机理研究和风电场无功电压控制奠定了基础。Recently, Cascading trip-off of wind turbine generator occurred frequently. These indicate that safe and stable operation of the wind farm is impacted by reactive power and voltage distribution of wind farm col- lector system. This article describes the outline of the wind farm collector system, and then analysis the spatial and temporal distribution of wind farm collector system reactive power, the voltage distribution characteristics of wind turbine, the impact factor of the voltage of wind generator and the impact of wind power fluctuations on generator voltage. This is basis of analyzing on mechanism of large scale cascading trip-off of wind turbine gen- erator and controlling reactive power and voltage in wind farm.
