DC Voltage Balance Control Strategy Among Phases for Cascaded STATCOM
静止同步补偿器(static synchronous compensator,STATCOM)普遍采用链式结构,换流链由若干结构相同的H桥链节级联组成.链节直流电压的稳定是保障装置可靠运行的必要条件.通过对换流链功率方程的分析,阐述实现换流链相间直流电压平衡控制的基本数学原理,提出一种基于负序电流的相间直流电压平衡控制思想,并考虑了系统电压不平衡的影响.仿真分析和工业样机实验表明,所提计及系统电压不平衡的链式STATCOM相间直流电压平衡控制策略…查看全部>>
Chain structure is widely used in static synchronous compensator (STATCOM), which is composed of several H-bridge modules with identical structure. The stability of DC voltage of each converter determines the stability of the device. This article analyzed the converter chain power equation, sets forth the basic mathematical principles to achieve DC voltage balance control among the converter chains, and put forward an averaging DC voltage control strategy ba…查看全部>>
