摘要
在电力电子装置中,大功率开关器件很大程度上决定设备的技术经济指标。以南方电网35kV/±200Mvar链式静止同步补偿器(STATCOM)工程应用为背景,介绍了电子注入增强门极晶体管(IEGT)的基本结构、工作原理和性能特性分析,并与绝缘栅双极性晶体管(IGBT)与集成门极换向晶闸管(IGCT)的参数进行对比,阐述了基于IEGT的功率相模块结构及工作原理,并对其进行了试验验证。试验结果表明IEGT具有优越性,可作为高压大容量STATCOM功率开关器件的首选。所得结论经南方电网STATCOM实际工程应用验证,可供高压大容量STATCOM设计借鉴。
The technical and economic indicators of power electronic devices are mostly determined by switching devices of large power.Based on engineering applications of Southern Power Grid（SPG）35kV/±200Mvar cascaded STATCOM,the basic structure and the operation principle of injection enhanced gate transistor（IEGT）is briefly treated,and the performance characteristics are analyzed and compared with the parameters of integrated gate commutated thyristor（IGCT）and insulated gate bipolar transistor（IGBT）.The phase-module of IEGT and the operation principle are dealt with,and the superior characteristics of phase-module are verified by experimental results.The research shows that IEGT should be the first choice of power switching devices of the high-voltage and large power STATCOM.The conclusions obtained have proved useful in actual project application of China SPG,providing a reference for high-voltage and large power STATCOM design.
