摘　　要：结合目前我国风电场的普遍运行情况,针对山西省电网的特点,在风力发电机组无功功率与电压特性的基础上,从实例出发,通过各种运行方式和工况下的模拟潮流计算,分析各种不同因素对包含风力发电电力系统的电压性能产生的影响,研究这些不同因素的影响,给出了可以通过系统运行方式的调整、限制风电机组功率因素变化范围、增加无功补偿装置等办法来提高地区电网接入点风电装机容量。Combining the present wind farm operation modes and the characteristics of Shanxi power grid, this paper analyzes the influence of different factors towards the voltage profile of the grid-connected wind farm system and then deduces some useful conclusions, through the power flow calculation under various operation conditions, based on the relationship between the reactive power of wind power generator and its corresponding terminal voltage magnitude. This paper also gives some measures to increase the penetration capacity of wind power, such as adjusting the operation mode of power system, restraining the variation range of wind power generator＇ s power factor, installing the VAR compensator, etc.
