中文摘要: 限流器面临的是故障电流工况,传统过电压保护技术不适合限流器装置.为了得出参数的合理范围,建立了阻抗模型,得出了限流指标与限流参数的函数关系.为了降低晶闸管阀电流应力水平,研究了保护装置换流过程,分析了故障状态下晶闸管阀的应力水平.对主电路结构进行了优化设计,提出了新型过电压保护电路方案.
Abstract:Traditional overvoltage protective technology can not be used for series fault current. In order to obtain reasonable parameter range,the impedance model is established and the current limiting index and limiting parameter function are concluded. For reducing the thyristor valve current stress level,the protection device commutation process is studied,and the fault of thyristor valve stress level is analyzed. The main circuit structure is optimized,and a new protective circuit design is introduced.
