Problems solved by technology
[0004] In order to overcome the deficiencies of the above technologies, the present invention provides a method that changes from passive maintenance to active defense, reduces the workload of debugging and operation and maintenance, and solves the problem of difficult operation and maintenance. For the problem of alarm and misoperation, by uploading the self-operation and maintenance information of the local module and cooperating with HSR redundant communication, the precise location of the fault can be realized, and the self-operation and maintenance method of the local module can solve the problem that the fault of the process layer equipment is difficult to locate

Embodiment Construction
[0031] Attached below figure 1 , attached figure 2 , attached image 3 The present invention will be further described.
[0032] combined with figure 1 , a self-operation and maintenance method for in-place modules, including:
[0033] a) After the local module is powered on, it enters the start-up self-inspection program, which includes control system self-inspection, communication self-inspection, and digital tube display function self-inspection. Step b) is executed after the start-up self-inspection passes. If the self-inspection If not, go to step d).
[0034] b) Formulate the corresponding fault diagnosis priority structure according to the functional requirements of different local modules. After the local module completes the startup self-inspection, the fault of the local module is self-diagnosed according to the priority structure.
[0035] c) Code all faults for self-diagnosis, set variables to store fault codes, and set variables to store the flags of each fa...

The invention discloses a self-operation and maintenance method for an in-situ module, which improves the operation reliability and the intelligent level of a device, converts passive detection into active defense and automatically identifies hidden faults through fault self-diagnosis and self-operation and maintenance, basically realizes full coverage of possible problems of the device, and by uploading the self-operation and maintenance information, the accurate positioning of the fault and the determination of the fault reason can be realized, and the debugging and operation and maintenance workload is reduced. A classification and grading method is adopted for fault processing, and false alarm and false operation of the device are avoided. The self-operation and maintenance method has universality and universality, can be transplanted to all types of in-situ modules of the transformer substation, and has high application value.
Description
technical field [0001] The invention relates to the technical field of power systems, in particular to a method for self-operation and maintenance of in-situ modules. Background technique [0002] At present, monitoring IEDs, merging units, intelligent terminals and other process-level equipment are used in substations. There are problems such as high hardware failure rate and many software defects. The operation reliability is poor, and false alarms and malfunctions are prone to occur. It performs precise positioning; the monitoring IED, merging unit, intelligent terminal and other equipment are arranged in the intelligent control cabinet, and there are defects such as long cable or optical fiber wiring distance between the primary and secondary equipment, and dense wiring in the cabinet. Operation and maintenance bring a lot of difficulties, usually only power outage maintenance, can not meet the third-generation intelligent station "intelligent inspection, free (less) mai...
