Study on Over-voltage Calculation System in Gas Insulated Substation

At present,VFTO is calculated by using EMTP which need the operator to study solid knowledge in the theory of overvoltage and it is difficult to the operator.Therefore,the development of calculation system for VFTO simulation that has friendly interface has great importance.On the basis of the developing platform Microsoft Visual Studio 2008,C# of Microsoft is applied to develop the GIS Transient Calculation system(GISTCS) for VFTO simulation based on the Bergeron Method.It can also calculate the transient process with the different operations in GIS.
