风力发电场选用的风力发电机组大多具有无功功率控制能力,功率因数可控制在0.95以上。如果需要,可调节无功为容性无功,这种无功功率的控制能力使用工户可以在功率系统中调节电压。因此单台机组无需无功补偿。风电场的集中无功补偿应设置在风力发电场升压变电所主变低压母线上,以确保风电场升压变电所出口侧功率因数维持在1。0左右,利于电力系统稳定运行。风电场发电机组随风力变化出力变化较 Most of the wind turbines used in wind farms have reactive power control capability, and the power factor can be controlled above 0.95. If required, reactive power is adjustable to capacitive reactive power, which allows the customer to adjust the voltage in the power system. Therefore, a single unit without reactive power compensation. The concentrated reactive power compensation of wind farm should be set on the main transformer low voltage bus of the wind farm to ensure that the power factor at the outlet side of the step-up substation in the wind farm is maintained at about 1.0, which is conducive to the stable operation of the power system. Wind farm generator varies with wind power
