Investigation of Initial Voltage Distributions in HV Windings of Shunt Reactors Taking Transient over Voltages into Account
Keywords:Shunt reactors, high voltage winding types, initial voltage distribution, analytic method, ATPDraw tools
Shunt reactors operating in high and supper voltage systems are usually influenced by voltage impulses that cause transient over voltages. Many authors have been recently studied influence of fringing fluxes around air gaps, leakage inductances and the number of air gaps to the shunt reactors. The novel idea of this paper is to investigate initial voltage distributions with different types of high voltage shunt reactor’s winding when affected by a lightning impulse. In order to make the uniformly distribution in the winding, it is necessary to change the winding type by increasing series capacitance values. Thus, the model of shunt reactor’s winding will be proposed via an analytic technique to compute capacitance components in the windings. Then, the obtained results from the analytic method are introduced to the ATPDraw tool to simulate and investigate the voltage distributions in high voltage windings.
