摘要
应用数字仿真（EMTDC／PSCAD）和动态模拟实验（15kvar物理模型）对比研究了超高压可控串联补偿（TCSC）与电力系统暂态稳定控制有关的一些重要的动态特性。通过数字和物理仿真分析了不同同步信号（电容电压同步和线路电流同步）、不同控制模式（阻抗开环和阻抗闭环控制）对TCSC装置动态品质的影响；提出并实现了TCSC装置硬件阻断（block）与旁路（bypass）工作模式。提出了TCSC在容性与感性区间内实用的平稳转换两步骤方法，以及避免故障下TCSC失控和减小电容器直流分量的控制策略。
Several important dynamic characteristics of EHV TCSC related to transient stability control of power system arestudied by use of digital simulations and physical experiments. This paper analyzes the impacts of synchronous signals andcontrol modes on TCSC dynamic behavior. presents and realizes a new working mode of TCSC device. namely hard block andbypass operation patterns. It also introduces a practical two-stage method for smooth transition of TCSC between capacitiveand inductive regions, and proposes a control strategy to avoid TCSC device out of control as well as to decrease the DCcomponent across the series capacitor.
