并联电容器组投切问题新的计算法

The New Computing Method about the Switching Problems of Bridging Condenser

利用拉普拉斯转换法代替待定系数法,计算并联电容器组合闸涌流和过电压的暂态分量,使计算过程大为简化。首先得到分闸过电压新的计算公式,结束了传统应用的分析法,使对分闸过电压的理解更为完善。

This article using the Laplac＇s transform instead of the coefficient determined to solve the problems of the inrushing current and over - voltage in transient of switching shunt capacitor bank. The mathematical expression for calculating the over - voltage that was due to the circuit breaker of bank tripping was given firstin the world. Because this calculating process is very simple, time short and apprehending easily , so that, the application of the convention method to analyze the over- voltage occurrence should be ended.
