由中国电科院研制的2台35kV Mvar静止无功补偿器在甘肃330kV玉门变电站成功挂网运行,这是国内首套应用于风电集中送出通道的静止无功补偿装置,同时,也是该装置在甘肃电网系统的首次应用。玉门变电站是甘肃风电外送的汇合点,风电功率变化频繁,无功波动较大,母线电压的控制难度大 Two sets of 35kV Mvar static var compensators, developed by China Electric Power Research Institute, were successfully put into operation in 330kV Yumen Substation in Gansu Province, which is the first set of static var compensator used in China to send out concentrated wind power. At the same time, it is also the device First Application of Gansu Power Grid System. Yumen Substation is the meeting point of Gansu’s wind power outsourcing. The power of wind power varies frequently and the variability of reactive power is large. The control of bus voltage is difficult
