Embodiment 1

[0023] Example 1: as figure 1 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 the 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. At the end of each single method executed, submit the inspection data, and then call the reasoning method in the single method to obtain the operation result of this single method, that is Check whether the equipment under inspection is abnormal and where the abnormal data appears. After executing all single methods, the results of all single methods will be obtained;

[0026] Step 3: Invoke the reasoning method in the inspection work order, process the total inspection data results obtained by the reasoning method in the method set, and return the fault code of the work order...

Abstract

The invention discloses a digital substation inspection method. The system includes the following steps: acquiring and analyzing a method set according to the type of work order; executing each method in the order of the numbers representing the methods in the method set; executing each single method at the end , call the reasoning method of this method to get the execution result of this method; when a complete method set is executed, call the reasoning method in the work order type to get the final execution result of this work order, that is, the fault code; finally According to the operation and maintenance knowledge base corresponding to the fault code, the operation and maintenance of the substation fault is carried out. The invention firstly performs unified inspection on the equipment of the substation, and then calculates the inspection result of the equipment by the inference method, reduces the requirement of human judgment, and ensures the standardization and safety of the inspection process of the substation.

Description

technical field [0001] The invention relates to a digital substation inspection method, which belongs to the technical field of substation inspection methods. Background technique [0002] In digital (smart) substations, due to the use of optical fiber digital communication, the entire metering device has undergone major changes compared with traditional substations, related equipment, and operation, inspection and maintenance work. Currently, measurement 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 improve the intelligence level of the relay protection device test and improve the work efficiency and accuracy of the on-site power secondary operation through technical means. . SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is: aiming at the problems that the ex...
