摘要
高压变电站、发电厂是具有高强度电磁场环境的特殊区域 ,容易对继电保护装置造成干扰 ,使保护误动或拒动 ,危及系统安全稳定运行。为此 ,介绍了现阶段广东省所采取的若干抗干扰措施 ,并对这些措施的原理及实现方法进行了简单的阐述。
High-voltage transformer substations and power stations have intense electromagnetic disturbance and easy to make the relaying protection equipments have unwanted operations or a failure to operate. This article introduces some ways to restrict those disturbances now in Guangdong and explains the theory of those means.
