Measurement and control device maintenance method and device for realizing state maintenance strategy

Abstract

The invention discloses a measurement and control device maintenance method and device for realizing a state maintenance strategy, and the method comprises the steps of collecting the state data of each module of a device, carrying out the classification of the state data, creating an evaluation matrix, carrying out the normalization processing, obtaining other parameters, such as temperature and dynamic adjustment weight, and finally outputting an evaluation result. After each module is evaluated, the health state of the whole machine of the device is evaluated by using the same method. And finally, a health evaluation result by is output by the APP. Besides outputting a health evaluation result, the collected data and the intermediate data can be uploaded to a monitoring host or uploaded to a scheduling master station through an edge intelligent gateway machine so as to provide data support for other evaluation methods. The invention has the function of monitoring the health state of the measurement and control device online in real time, provides data support for a device maintenance strategy, realizes the state maintenance strategy of the device, and ensures safe and stable operation of a power grid.

Description

technical field [0001] The invention relates to a method and device for overhauling a measurement and control device for implementing a condition-based maintenance strategy, and belongs to the technical field of electric power automation measurement and control. Background technique [0002] With the continuous improvement of the automation degree of the power system, the automation system of the power grid is more and more dependent on the automation equipment. In particular, in recent years, a new generation of dispatching system D5000 has been put into operation in large quantities, and the advanced application functions of the system have been gradually deployed. It all depends on the safe, stable and reliable operation of plant automation equipment. [0003] As the main secondary equipment of the automation system, the health status of the measurement and control device directly affects the safe and stable operation of the power grid. The "bathtub curve" of the device...
