Amendment on Estimated Formula of Capacitive Current of Power Distribution Grid

配电网电容电流估算公式是配电网设计中的常用公式。随着线路增多和设备变化 ,传统的估算公式出现了很大误差。为此 ,分析了造成公式误差的原因 ,重新推导出了新估算公式 ,对从事电力建设工程技术人员有极大的实用价值。

The estimated formula of capacitive current of power distribution grid is often used in the design of power distribution grid. With the increase of the cable line and the variation of the distribution equipment, the traditional estimated formula has great diviation. In this paper, the reasons causing the deviation of the traditional formula are analyzed, and a new estimated formula is put forward, wich is of great practical value to the technical personnel engaged in the construction of power grid.
