摘　　要：分析并列出了四射线补偿方法下并联电抗器在不同的补偿度下小电抗的大小、所应耐受的最大工频电压和暂时功率的计算公式 ,并给出了相应的曲线。指出应该避开电抗器的全补偿运行方式。超高压线路中的可控电抗器应具有高速响应能力 ,文中叙述了它的三角形接线的优点 。The four radial compensated method of shunt reactors is widely used in our country. For the different degrees of compensation this paper presents the formulae for computing the neutral inductance, the power frequency withstand voltage and the temporary power. It is necessary to avoid the full compensation mode of reactors. The controllable reactors on EHV lines must have high speed response ability. This paper describes also the merit of controllable reactors with triangle connection and the controlled mode in case of star connection.
