摘要
在电力系统中,最大限度地发挥输电线路的设计容量和提高系统运行稳定性的问题日益突出,大功率冲击性负荷和不平衡负荷也日益严重。由晶闸管控制电抗器(TCR)和晶闸管投切电容器(TSC)构成的静止无功补偿器(StaticVar Compensator,SVC)可以就地提供动态无功补偿,是解决这些问题的经济有效的方法。自上世纪70年代SVC开始投入商业运行以来,30多年间世界各国都不断有SVC投入运行,并取得可观的收益。目前有资料记载的绝大多数SVC项目,特别是100MVar以上的大容量项目,都是由少数大型跨国公司承接的,如ABB、阿尔斯通和西门子等。本文介绍在日本和纳米比亚进行的[(SVC)-238.1(\317\356\304\277\243\254\322\324)]此说明SVC的设计特点。
In power systems, increasing transmittable power along a line becomes demanding, and suppressingvoltage flicker due to fluctuant loads becomes imperative. Using a Static Var Compensator (SVC) composed of athyristor controlled reactor (TCR) and thyristor switched capacitors (TSCs) to provide dynamic var compensation isefficient to solve above problems. There are many SVCs in commercial use in electrical power systems since theearly 1970s, and considerable benifits have been achieved. Most of SVCs with data recordation, especiallyover100MVar, are produced by several large transnational companies, such as ABB, Alstom, Siemens. In thispaper, some applications of SVCs are described, such as SVC projects in Japan and Namibia , and design features ofSVCs are emphasized.
