500kV智能变电站压板状态监测及智能校核技术

Condition Monitoring and Intelligent Check Technology of Pressure Plate of 500kV Intelligent Substation

针对压板中存在的问题,本文提出了压板顺序投退原则、二次设备故障隔离原则,并对二次设备的压板进行在线监视,将监视的压板实时状态与相应的原则相结合,实现压板的自动、智能校核,能极大地提高二次设备的可靠性,为智能变电站运维检修作业的有效开展提供有力的辅助手段。

In view of the problems existing in the pressure plate,this paper puts forward the principle of plate sequence commissioning and ceasing and the principle of secondary equipment fault isolation,and conducts online monitoring of the pressure plate of the secondary equipment.Combining the real-time status of the monitored pressure plate with the corresponding principles,the automatic and intelligent check of the pressure plate can greatly improve the reliability of the secondary equipment and provide a powerful auxiliary means for the effective development of operation and maintenance operations of intelligent substation.
