Distributed log analysis based operation state monitoring method of power system

Abstract

The invention discloses a distributed log analysis based operation state monitoring method of a power system. The method comprises the steps of S1, acquiring log information of the power system, and combining into a log file; S2, segmenting the log file, processing to obtain the log information with the same format, respectively sequentially outputting the log information in the log file into a distributed storing system; S3, extracting the log information from the distributed storing system, classifying the log information by the log analysis algorithm based on state noise removing and clustering according to the Map-Reduce mechanism, and analyzing the classified log information to monitor the system operation state. With the adoption of the method, the abnormality in operation state of the power system can be timely found if any and can be handled at the first time, so that the requirement on timely and efficient operation of the power system can be effectively met.

Description

technical field [0001] The invention relates to a method for monitoring the operating state of a power system, in particular to a method for monitoring the operating state of a power system based on distributed log analysis, and belongs to the technical field of power system dispatching. Background technique [0002] With the increasing scale and complexity of the power grid, the UHV interconnected large power grid puts forward new requirements for the integrated operation and unified coordinated control of the power grid. come higher. Electric power big data emerged as the times require. It is the practice of big data concepts, technologies and methods in the electric power industry. Electric power big data involves power generation, power transmission, power transformation, power distribution, power consumption, and dispatching. Professional, cross-business data analysis, mining and data visualization functions. [0003] In the dispatching link of the power system, with ...

Problems solved by technology

[0004] The safe and stable operation of the power system requires the protection of local devices such as relay protection and automatic devices, but relying solely on these local devices cannot fully guarantee the safe operation of the power system, because these devices often process power based on local information system failures, but cannot use global information to predict and analyze system operation and deal with various complex problems in the system. For this reason, log analysis technology for system operation status monitoring needs to be developed urgently

[0005] At present, the system log analysis technology of domestic electric power enterprises is still immature, and the discovery of most system faults still relies on fault alarms and manual verification. The abnormal operation of the time cannot detect the abnormal operation of the system in time and deal with it in the first time, which greatly prolongs the operation and maintenance time of the system and cannot meet the timely and efficient operation requirements of the power grid system
