System for improving operation and maintenance efficiency of automatic system

Abstract

The invention belongs to the technical field of transformer substation control and particularly relates to a system for improving operation and maintenance efficiency of an automatic system. The system is characterized by comprising a main station system 01, a substation system 02, substation link communication 03, an operation and maintenance system 04, a monitoring system 05, a PDA terminal 06 and a short messaging service module 07. The monitoring system 05 is provided with a comprehensive information association unit 1; the operation and maintenance system 04 is provided with a channel failure diagnosis unit 2, a fault online handling unit 3, a model library 7, a database 8, a knowledge base 9, a system fault diagnosis unit 10, an alarm technique recognition unit 4, a remote command execution unit 5 and a case knowledge base processing unit 6. The system has advantages that system fault and channel fault accident management is remarkably improved; high compatibility, high reproducibility and low reproduction cost are realized, wherein the short messaging service module is about 500 yuan, and the mobile PDA terminal is about 2000 yuan; high economic benefits and social benefitsare created.

Description

technical field [0001] The invention belongs to the technical field of substation control, in particular to a system for improving the operation and maintenance efficiency of an automation system. Background technique [0002] With the explosive growth of the application scale of the power EMS system, the complexity of large-scale distributed system monitoring is also becoming more and more apparent. During the operation of the subsystem, failures such as process interruption, memory crossing, and CPU overload will occur. Proper handling, while the real-time performance of traditional manual maintenance solutions is difficult to guarantee, and fault handling during non-duty hours is even more difficult to control, resulting in the black swan phenomenon of downtime caused by monitoring omissions from time to time. In addition, when the system fails, it is difficult for the operation and maintenance personnel to quickly find the root cause of the failure from the massive monit...

AI Technical Summary

Problems solved by technology

[0008] ■There is no way to predict equipment failure in time according to the change of equipment parameters, and it is impossible to find problems in advance

[0009] ■There are differences in the technical level of the on-duty personnel, and there is a possibility that the cause of the fault cannot be accurately judged and eliminated, which will prolong the time for troubleshooting
