摘要
近年来伴随着国民经济快速发展,对区域内电力负荷要求越来越高,传统的交流配电网面临着电能质量降低和输电走廊受限等问题,而电力电力技术的发展,带动了直流配电网的发展,使其具有更广阔的上升空间,尤其是在提高电能质量等方面优势愈加明显,必将是未来配电网的发展趋势。本文从直流配电网的国内外现状入手,阐述了直流配电网的电压等级选择,优点,故障类型以及常用的故障隔离装置,最后对直流配电网的发展前景进行了总结。
In recent years,with the rapid development of the national economy,the demand for regional power load is higher and higher.The traditional AC distribution network is facing the problems of power quality reduction and transmission corridor limitation.The development of power technology has driven the development of DC distribution network,which has a broader rising space,especially in improving the power quality and other aspects It will be the development trend of distribution network in the future.Starting from the current situation of DC distribution network at home and abroad,this paper expounds the selection of DC distribution network voltage level,advantages,fault types and common fault isolation devices,and finally summarizes the development prospect of DC distribution network.
