特高压GIS中暂态壳体电位的暂态模型研究

Research on Transient Model of Transient Enclosure Over Voltage in UHV GIS

随着电压等级的提高,电磁暂态过程对电力系统造成的影响不容忽视,为了特高压变电站的长期安全运行,不断优化细化模拟暂态计算电路为其提供精确的理论数据参考至关重要。以浙南1 100 k V GIS变电站隔离开关操作时引起的TEV为例,进行建模和计算,得到了该操作方式下TEV特性,与理论TEV特性对比,符合理论情况,因此可得该计算模型可信。

With the increase of voltage grade, the effects of electromagnetic transient process of power system should not be ignored. In order to provide the theoretical reference for UHV substation, continuous optimization models is very important. This paper does some calculations and analysis on the TEV which occurs in 1 100 kV substation of Zhenan. Comparing the actual characteristics of TEV with the theoretic characteristics of TEV, it conforms to the theory of situation. The transient model can be trusted.
