Research on Transient model of Transient Enclosure Overvoltage in UHV GIS

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. In this thesis, we do some calculations and analysis of the TEV which occurs in 1100kV substation of south district of Zhejiang province. Compare the actual characteristics of TEV with the theoretic characteristics of TEV. Conform to the theory of situation. The transient model can be trusted.
