摘要
分析现阶段我国施工建设的电力工程应用情况可知,受多种因素影响,导致变电所继电保护装置非常容易发生电磁干扰问题,使得继电保护装置的保护电力设备作用不能有效发挥,严重影响电力系统的运行安全性与可靠性。因此,要求电力企业采取针对性的解决方案进行处理,增强继电保护装置的抗电磁干扰能力,确保电力系统能够正常稳定的运行。基于此,对变电所继电保护电磁干扰问题涉及的相关内容进行了概述,并结合具体的故障案例进行了有效解决方案的探究,总结了抗电磁干扰的常用手段。
Analysis of the present stage our country construction of power engineering application is affected by many factors,lead to substation relay protection device is very prone to electromagnetic interference problem,which relay protection device to protect the action of electric power equipment cannot effectively play,seriously affect the operation safety and reliability of power system,so require power companies to adopt targeted solutions for processing,enhance the ability to resist electromagnetic interference of the relay protection device,to ensure normal and stable running of power system can be.Based on this,summarizes the related contents involved in the electromagnetic interference problem of substation relay protection,and combined with specific failure cases to explore the effective solution,summarizes the common means of antielectromagnetic interference,so as to provide guidance for more power enterprises to follow the substation relay protection anti-electromagnetic interference.
