直流融冰装置主参数设计与仿真

Design and Simulation of Main Parameters of DC Ice-melting Device

为了应对冰雪灾害,南方电网在存在线路覆冰灾害的变电站陆续配置了直流融冰装置。但直流融冰装置的参数设计需考虑诸多因素,合理的直流融冰参数的确定可很大程度提高直流融冰装置的使用效率。分析了变电站配置直流融冰装置需考虑的因素和步骤,并对直流融冰装置主要参数进行设计,最后针对某变电站在PSCAD环境下进行仿真分析,结果验证了直流融冰装置主参数设计的正确性。

In order to cope with snow and ice disasters,China southern power grid has successively installed DC ice-melting devices in substations with line icing hazards.But the design of parameters of DC ice-melting devices needs to consider many factors.The reasonable determination of DC ice-melting parameters can greatly improve the efficiency of DC icemelting device.This paper analyzes the factors and steps to be considered in the configuration of DC ice-melting device in substation,designs the main parameters of the DC ice-melting device,and finally makes a simulation analysis under the PSCAD environment for the conditions of a substation.The simulation results verify the correctness of the design of the main parameters of the DC ice-melting device.
