浅析微机继电保护抗干扰研究

Study of Anti-Microprocessor-Based Relay Protection

变电站是复杂电磁环境的代表,发电厂、变电站的强电磁对微机保护装置的可靠性威胁很大。为了节约电缆、减小工程量和提高运行的安全可靠性,众多变电站项目都将继电保护设备安装于变电站的开关场地中。本文就微机继电保护装置工作环境中的电磁骚扰进行分析,并就微机继电保护装置抗干扰的常规措施进行相关探讨。

The substation is a representative of the complex electromagnetic environment. Currently, power plants, substations strong electromagnetic protection devices on the computer a great threat to the reliability. To save the cable, reducing the work capacity and enhanced safety and reliability of operation, a large number of substation equipment, relay protection project will be installed at a substation in the switch venues. In this paper, microprocessor-based relay protection device on the working environment in the analysis of electromagnetic harassment and interference on the microprocessor-based relay protection devices related to conventional measures to explore.
