摘要
结合伊—冯输电系统 ,给出可控串联补偿 ( TCSC)基本控制和保护方法数字仿真的初步结果。其中包括内层驱动方式和中层阻抗控制方式的比较。在此基础上讨论了在短路故障时 ,TCSC过电压保护控制方式对过电压保护水平和金属氧化物限压器 ( MOV)
This paper presents the digital simulation results of basic control and overvoltage protective control for Yi-FengTCSC system. It includes the comparisons among different control methodologies for the inner-level thyristor firing controland medium--level impedance-control. Based on this comparison, the control methodology for TCSC overvoltage protection isdiscussed. As the results of this study, the energy requirement of metal--oxide varistor (MOV) and protection level of YiFeng TCSC are also presented.This project is supported by National Natural Science Foundation of China (No. 59637050) and State Power Corporationof China.
