摘　　要：在介绍可控并联电抗器的技术特点及应用状况的基础上,分析了1 000kV分级式可控并联电抗器的接线与工作原理,并对主要设备参数进行选择,结合实际情况,提出适用于特高压变电站的1 000kV分级式可控并联电抗器布置方案。该方案可控并联电抗器额定容量大,高压侧三相绕组采用星形连接,中性点经小电抗器接地;低压侧三相绕组采用星形连接,中性点直接接地。便于设备选择及降低设备绝缘水平,满足了可靠性、灵活性和经济性的要求。The paper analyzed the wiring and working principle of the 1 000 kV classifying controllable shunt reactor based on the technical characteristics and application status of the controllable shunt reactor, and selected the main equipment parameters. Proposed for UHV substation of 1 000 kV rated controllable shunt reactor arrangement combined with the actual situation. The scheme of controllable shunt reactor rated capacity is big. high-voltage side-three-phase winding adopts star connection, the neutral point by a small reactor grounding. l.ow-voltage side three-phase windins adopts star connection, neutral point is grounded directly, equipment is easy to choose and reduce equipment insulation level, and meet the requirements of reliability, flexibility and economy.
