Embodiment 1

[0023] Embodiment 1: as figure 1 Shown, a digital substation inspection method, the method includes the following steps:

[0024] Step 1: Issue a work order. The information of the work order includes work order type, work order name, work order description, method set, equipment type, and reasoning method;

[0025] Step 2: Execute the single methods in the method set in the inspection work order in sequence, submit the inspection data at the end of each executed single method, and then call the reasoning method in the single method to obtain the operation result of this single method, namely Whether the inspected equipment is abnormal and where the abnormal data appears, after executing all the single methods, the results of all the single methods will be obtained;

[0026] Step 3: Call the inference method in the inspection work order, use the inference method to process the total inspection data results obtained in the method set, and return the fault code of this work ord...

Abstract

The invention discloses a digital substation inspection method, which comprises the following steps of obtaining and analyzing a method set according to the type of a work order, executing each methodaccording to the sequence of numbers representing the methods in the method set, calling an inference method of the method at the execution end of each method to obtain an execution result of the method, after a complete method set is executed, calling an inference method in the work order type to obtain a final execution result, namely a fault code, of the work order, and finally, according to the operation and maintenance knowledge base corresponding to the fault code, conducting transformer substation fault operation and maintenance. Unified inspection is carried out on the equipment of the transformer substation, and then the equipment inspection result is calculated by the inference method, so that the manual judgment requirement is reduced, and the standardization and safety of thesubstation inspection process are ensured.

Description

technical field [0001] The invention relates to a digital substation inspection method and belongs to the technical field of substation inspection methods. Background technique [0002] Digital (smart) substations, due to the use of optical fiber digital communication, compared with traditional substations, the entire metering device has undergone major changes in related equipment, inspection and maintenance work, and current metering professionals are facing many difficulties. [0003] After a lot of research, it is found that the traditional manual test mode cannot guarantee the test accuracy and work efficiency. Therefore, it is necessary to use technical means to improve the intelligence level of relay protection device testing and improve the work efficiency and accuracy of on-site power secondary operations. . Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a digital substation inspection method for the e...
