基于电压控制的LC振荡放电融冰电源研究
Research on LC Oscillation Discharge Deicing Power Supply Based on Voltage Control
摘要
Abstract
The skin effect of high-frequency current increases the heat loss caused by the current in the conductor,which provides a new technical method for deicing on transmission lines.In this paper,a kind of high frequency deic-ing method based on LC oscillating discharge is proposed.The high frequency current is obtained by controlling the voltage square wave by using the characteristics of current change caused by capacitor charge and discharge when the RLC series circuit is converted from one to another steady state.This method can effectively reduce switching fre-quency of IGBT and reduce switching loss.According to the characteristics of IGBT,a set of deicing power supply is designed.The simulation experiments show that an effective deicing current of 1 kHz can be obtained for LGJ-400/50、LGJ-240/40、LGJ-120/25 and LGJ-70/10 of wire with lengths of 40 km and 35 km.关键词
