摘　　要：1000kV变电站主变低压侧的并联电容器组是特高压电网无功调节的重要装置。与超高压电网相比,特高压变电站低压并联电容器组的电压更高、容量更大,其参数选择有其特殊性。文章结合特高压试验示范工程,确定低压电容器组的分组方式及最大分组容量,研究电容器装置的额定参数选择和接线方式,并对电容器装置的合闸涌流进行校核。The shunt capacitor bank at low voltage side of main transformer in 1000kV substation is an important device for reactive power regulation. The voltage borne by shunt capacitor bank at low voltage side of main transformer in 1 000 kV substation is higher than that used in EHV power network and its capacity is higher than that used in EHV power network too, thus the parameters selection of shunt capacitor bank at low voltage side of main transformer in 1 000 kV substation possesses its own particularity. Based on 1000kV power transmission pilot project in China, the grouping mode of such a low voltage capacitor bank and its maximum group capacity are determined, the selection of rated parameters of the shunt capacitor device and its connection mode are researched, besides, the close inrush current of the shunt capacitor device is verified.
