变电站保护装置状态监测的优化和异常处置

Optimization and Abnormal Disposal of Condition Monitoring for Substation Protection Device

摘要:

随着变电站二次系统的不断发展，对于二次设备状态，特别是继电保护装置状态的监测越发重要。基于采集保护装置自身各类信号形成的站端和主站状态监测系统已经全面推广，但由于监测规模和信号数量的不断膨胀，对保护装置的状态监测呈现复杂化、无序化的趋势，运维人员也难以高效排查处置保护装置异常。文中首先多角度分析了现有站端保护装置监测系统的优缺点，进而从现场实际出发提出优化保护装置状态监测的方案。在优化状态监测信号以及显示的同时，结合实际运行维护经验，提出并讨论了发现、处置、报送保护装置异常的标准流程。

Abstract:

With the continuous development of substation secondary system, monitoring the status of secondary equipment, especially relay protection devices becomes much more important. The condition monitoring system in the station and remote terminal based on the collection of various signals of protection devices has been widely promoted. However, due to the expansion of the scale and the quantities, the condition monitoring of protection devices presents a trend of complexity and disorder. And it is hard for the operation and maintenance personnel to efficiently troubleshoot and deal with the abnormal problems. Firstly, the advantages and disadvantages of the existing monitoring system for in-station protection device analyzed from multiple perspectives, and then a scheme to optimize the monitoring system is put forward from on site experience. While optimizing the signal and display of condition monitoring, a standard process of finding, disposing and reporting the abnormal problems of protection devices based on the practical operation and maintenance experiences is also proposed.
