摘　　要：论述了应用于500kV川渝输电系统的静止无功补偿器的控制调节策略,对川渝电网500kV人工单相瞬时接地短路试验中静止无功补偿器的动态响应行为进行了描述,通过超高压远距离输电网大扰动试验验证了静止无功补偿器对稳定川渝500kV系统电压、阻尼潮流断面有功功率振荡、提高川渝电网系统的暂态稳定性等实际作用。The authors discourse upon the control strategy of static var compensator （SVC） being applied in 500kV Chuanyu power grid, describe the dynamic response behavior of SVC while the test of artificial temporary single-phase earth fault is exerted on 500kV Chuanyu power grid. By means of large disturbance test performed in long distance 500kV transmission network, the practical functions of SVC, such as stabilizing system voltage of 500kV power grid, damping active power oscillation in tie-line, enhancing transient stability of Chuanyu power grid, are verified.
