【摘要】 上海西郊变电站静止同步补偿装置(STATCOM)由链式逆变阀、开关柜、静发变、就地控制/监测/保护/电源柜、水冷系统、控制台等组成。它采用集成门极换向晶闸管(IGCT)功率器件,以三相大功率电压逆变器为核心,具有恒无功和恒电压2种运行方式,具备快速的电压动态支撑能力。文章介绍了阀相关设备的单体调试、分系统调试、系统调试和性能测试。测试表明,STATCOM响应时间小于40ms,无功输出为-36~+50Mvar并可连续调节。西郊变电站STATCOM经过半年的试运行,主要指标基本达到了设计要求。更多还原

【Abstract】 STATCOM in West Suburb Substation in Shanghai is composed of chain-type inverters,cabinet breaker,step-up transformer,local controlling/monitoring/protecting/power cabinet,water-cooling system,console,etc.,which uses IGCT power electrical devices and is based on three-phase high-power inverters.It has two operational modes:constant reactive power mode and constant voltage mode,and owns rapid dynamic voltage supporting ability.This paper introduced the debugging of equipment,subsystem,system and performance test of STATCOM.STATCOM response time is less than 40 ms,reactive power output range is from-36 Mvar to 50 Mvar and can be continually adjusted.The test results show that the integral properties of this STATCOM reach the international advanced level.After half year trial operation,the main performance indexes of STATCOM is satisfied and basically fulfill the design demands.更多还原
