| 摘 要： | 介绍一种新型的多级注入式电流源变换器,这种变换器主桥实现了零电流切换,消除开关损耗的同时降低了对吸收回路的要求,简化了变换器与交流系统的连接,在换向期间网侧不需要大容量的交流电容。建立了基于多级注入式电流源变换器的STATCOM的数学模型,对STATCOM的非线性数学模型进行局部线性化。通过分析给出了控制策略框图,利用PSCAD/EMTDC对所建模型进行仿真,结果表明,该结构的STATCOM具有良好的动态、稳态特性,并验证了所提出控制策略的可行性。

| Abstract: | A novel multi-level current reinjection current source converter (MLCR-CSC) is proposed. The proposed MLCR-CSC implements the zero-current switching,which can not only eliminate the switching losses,but also simplify the requirement of the absorbing circuit and the connection of the converter with AC system is simplified and high-capacity AC capacitor at network side during the commutation isn't needed. The mathematical model of static synchronous compensator (STATCOM) based on the proposed MLCR-CSC is buil... |
