大型风电场接入电网可能引起电压闪变和波动、电压暂降、电压偏差以及谐波等电能质量问题。通常对风电场进行无功补偿可以抑制系统电压波动,而轻型直流输电则可以起到无功补偿的作用,抑制并网PCC点电压波动、改善风电场的并网性能。

Large wind farms connected to the grid may cause voltage flicker and fluctuations, voltage dips, voltage deviation and harmonic and other power quality problems. Usually the wind farm reactive power compensation can suppress fluctuations in the system voltage, HVDC can play the role of reactive power compensation and suppression grid PCC point voltage fluctuations and improve the performance of grid connected wind power.
