变电站直流系统中交流侵入问题分析

直流系统是变电站电网建设的重要内容,确保直流系统的稳定运行,能实现变电站整体的有效监测,为继电保护、控制和信号传输提供支撑。现阶段,交流侵入是变电站直流系统运行的主要问题。因此,在阐述交流侵入类型的基础上,就变电站直流系统中交流侵入的影响展开分析,并指出直流系统中交流侵入的应对策略。期望这有利于控制交流侵入问题,进而保证直流系统运行质量,实现变电站电网系统的现代化控制与管理。

Analysis of AC intrusion in DC system of Substation

DC system is an important part of substation power grid construction,which can ensure the stable operation of DC system,realize the effective monitoring of substation as a whole,and provide support for relay protection,control and signal transmission. At present,AC intrusion is the main problem in DC system operation of substation. On the basis of expounding the types of AC intrusion,it analyzes the influence of AC intrusion in DC system of substation,and points out the countermeasures of AC intrusion in DC system. It is expected that it is beneficial to control the problem of AC intrusion,and then realize the modern control and management of substation power grid system while ensuring the operation quality of DC system.
