摘要

本文描述了在220/33千伏阿达尼电力孟买有限公司(AEML)戈莱变电站连接220千伏电网的可变并联电抗器(VSR)的瞬态开关研究。该研究模型是在PSCAD中开发的。它包括VSR, Sf6 CB和其他变电站设备的模型。确定了无功功率最低48 MVAr(40%)和最高120 MVAr(100%)时，不受控制开关引起的涌流和强制5A电流斩波引起的暂态恢复电压峰值。在此基础上，提出了采用可控开关装置(CSD)实现120 MVAr VSR的点波开关策略，并设计了操作方法。

Transient Switching Study for 120 MVAr Variable Shunt Reactor at 220 kV Substation

This paper describes transients switching study carried out for variable shunt reactor (VSR) connected to 220 kV Grid at 220/33 kV Adani Electricity Mumbai Ltd (AEML) Gorai substation. The study model developed in the PSCAD. It includes a model for VSR, Sf6 CB, other substation equipments. Inrush currents due to uncontrolled switching and transient recovery voltage peak due to forced 5A current chopping corresponding to lowest 48 MVAr (40%) and highest 120 MVAr (100%) reactive power were determined. Based on the analysis, controlled switching device (CSD) was proposed for point on wave switching strategy for 120 MVAr VSR and operational methodology is devised.
