摘要
本文介绍了江苏沙河抽蓄电站水电机组振摆监测保护系统的国产化改进及应用情况。该系统基于继电保护系统硬件平台开发,实现了完善的通道自检功能和工况自适应浮动门槛判据,提高了监测装置故障告警的可靠性和灵敏性;后台分析软件可提供数据管理、在线监测和离线分析功能,减少了故障分析工作量。
In the paper,localization improvement and application of runout monitoring and protection system of Shahe Pumped Storage Power Station unit are introduced. The system is based on hardware platform development of relay protection system. Perfect channel self-detection function and working condition adaptive floating threshold criterion are realized,thereby improving the reliability and sensitivity of fault alarm monitoring devices. Background analysis software can provide data management,online monitoring and offline analysis functions,thereby reducing the workload of failure analysis.
