| 摘 要： | 当选择电容电压作为同步信号时 ,可控串被 (TCSC)的暂态过程会出现明显的超调和振荡 ,对于这一现象 ,前人还从未给出相应的机理解释。该文以晶闸管导通角为建模对象 ,采用拓扑建模法建立了能描述电容电压同步下TCSC暂态特性变化规律的二阶差分数学模型。借助该模型可分析影响暂态过程的相关因素 ,进而从本质上揭示了电容电压同步下TCSC的暂态机理。数字仿真结果验证了所建模型的正确性。

| Abstract: | When the capacitor voltage is taken as synch ronizing signal, there is obvious overshoot and oscillations in Thyristor Controlled Series Compensation(TCSC) transients. However, the mechanism for this phenomenon is not explained in existing literatures yet. By the Topology method , this paper chooses conduction angle of thyristors as the object function and builds a two order difference equation mathematical model describing TCSC transient behaviors under capacitor voltage synchronization mode. Based on the derived model, the factors affecting TCSC transient characteristics are discussed. Also the transient mechanism of TCSC is revealed under capacitor voltage synchronization mode.The model is verified by digital simulation results. |
