| 摘 要： | 特高压系统低压无功补偿装置的并联电容器装置主要承担着大负荷输送功率时改善电压和提高功率因数的重要作用。并联电容器装置的串联电抗器起着抑制涌流倍数、抑制高次谐波、限制短路电流的重要作用。而过电压阻尼器并联在串联电抗器两端,起着限制过电压和涌流的作用。

| Abstract: | UHV system low voltage reactive power compensation device of shunt capacitor device is mainly responsible for a large of load power transmission in order to improve the voltage quality and the power factor of the power system.Series reactor of shunt capacitor device plays an important role for inhibitory current multiples,suppressing harmonics and limiting short circuit current.While the overvoltage damper is parallel to the both ends of the series reactor,it may be limiting overvoltage and inrush current. |
