摘　　要：串联补偿广泛应用于增加高电压、长距离和大负荷送电系统的稳定性。电力电子技术的使用使串联补偿具有更大的灵活性与实用性,其优势可以从分2段布置的电容器组中看出来,其中可控串补(TCSC)和固定串补(FSC)设备均放在同一平台上。每段都使用一个独立的旁路断路器来分别将电容器组投入或退出(旁路)。《国际电力》在2004年第4期上介绍了西门子公司承接的中国天广平果站可控串补工程的一次系统设计,本期将介绍该工程的控制与保护系统设计方案。Series Compensation is widely used to increase stability in long-distance and heavily loaded transmission systems. With the application of power electronic devices new possibilities came up to provide series capacitors with a higher degree of flexibility and availability. The benefits can be demonstrated with the two double segment capacitor banks with one TCSC- and one FSC- segment combined on the same platform. Each segment can be inserted or bypassed sepa- rately by using two independent bypass breakers. The primary system design philosophy of Tian Guang TCSC scheme at Pingguo substation implemented by Siemens was published in the issue of 2004,(4) of the magazine. In this issue, the control and protection sysem of Tian Guang TCSC schem will be introduced.
