【摘要】 为准确理解 TCSC装置的暂态机理 ,以晶闸管导通角为建模对象 ,建立了线电流同步方式下描述 TCSC暂态特性的解析数学模型。在此基础上 ,详细分析了影响 TCSC暂态特性和响应时间的相关因素。基于暂态模型研究进一步发现 :线电流同步方式下 ,TCSC阶跃到低补偿区暂态过程会出现振荡。数字仿真证实了这一特殊暂态现象的存在。更多还原

【Abstract】 In order to clarify the transient mechanism of TCSC. this paper chooses conduction angle of thWistors as object andestablishes-an analytical mathematical model describing TCSC transient behaviors under line current synchronication mode.abased on the derived model, the factors affecting TCSC transient characteristics are analyzed in detail. In addition, theoscillation characteristic in TCSC transients is revealed when the firing angle steps into lower compensation region of TCSCand is verified by digital simulation.This project is supported by National Natural Science Foundation of China (No. 59637050).更多还原
