摘　　要：研究了梧州SVC装置应用于电力系统中的电压支撑作用,保证当出现电压跌落时,SVC装置的控制策略使设备对500kV电压起支撑作用。研究了梧州变电站加装SVC装置的实际应用的控制策略,通过设备控制保护系统RTDS仿真试验,测试SVC装置的实际V-I特性曲线与理论作比较,分析V-I曲线斜率对装置无功储备及对系统电压支撑的关系。研究结果表明,慢速导纳控制参数中调差率设定为0.02-0.03时,将大大提高装置正常运行方式下的无功储备,提升SVC装置抑制电压波动的性能。The paper studies voltage support role of SVC device in power system in Wuzhou, how to ensure that when there is a voltage drop, SVC device control strategy plays a supportive role to 500 kV voltage equipment. By studying the practical application of SVC device control strategy in Wuzhou substation, and control and protection system simulation test by RTDS, it tests SVC V-I characteristic curves of the actual device to compare with the theoretical value, and analyzes the relationship of slope of VI curve between reactive power reserves of the device and the system voltage support. The results show that the when slow transfer admittance slip control parameter is set to 0.02-0.03, it will greatly enhance the device＇ s power reserve under normal operation mode, and increase SVC device performance on inhibiting voltage fluctuation.
