| 摘 要： | 1 000 kV交流特高压变电站110 kV侧并联无功补偿电容器组具有电压等级高、容量大等特点。通过对1 000 kV晋东南—南阳—荆门特高压交流试验示范工程110 kV无功补偿装置的电容器和电抗器投切控制进行仿真分析,特高压输电系统因无功补偿装置频繁投切时产生的合闸涌流和系统电压波动不容忽视。讨论了110 kV磁控式动态补偿的设计方案,通过对设计方案进行仿真分析,结果表明采用磁控式动态无功补偿技术可以避免并联电容器组频繁投切,有效地稳定系统的电压波动。

| Abstract: | The shunt capacitor bank at 110 kV side of 1 000 kV ultra-high voltage（UHV）alternating current（AC）substation characterizes in large capacity and high voltage.In this paper,The inrush current at closing operation and system voltage fluctuation which are occurred due to frequent switching of reactive power compensation device of UHV system shall not be neglected throughout simulation analysis of capacitor and reactor switching control of 110 kV reactive power compensation device in 1 000 kV Jindongnan-Nanyang-Jingmen UHV AC pilot project.The design scheme of 110 kV magnetron type dynamic compensation is discussed.It is shown by simulation analysis result of the design scheme that the adoption of magnetically controlled dynamic reactive power compensation technology can avoid frequent switching of shunt capacitor bank and stabilize effectively voltage fluctuation of system. |
