A real-time analysis system and method for a power-off and power-on event based on stream processing

Abstract

The invention provides a real-time analysis system and method for a power-off and power-on event based on stream processing. The system comprises a front-end processor used for receiving message information reported by a terminal and generating logs; the log collection assembly which is used for obtaining message information of a terminal power-on stop event from logs generated by the front-end processor; a distributed message middleware which is used for receiving and caching the message information of the log collection assembly in a classified mode according to message types; The distributed cache component which is used for caching basic archive information, and the flow processing component which is used for analyzing a power-on stop event by utilizing a flow processing technology andpushing a power-on stop event analysis result to the third-party system; And the column type database component which is used for storing the analysis result of the power-off and power-on event. Thepower failure condition in the distribution network can be effectively monitored in real time, so that the power failure response time and the first-aid repair time are shortened, and the power supplyreliability is improved.

Description

technical field [0001] The invention relates to the technical field of power metering, in particular to a system and method for real-time analysis of power-off and power-on events based on distributed stream processing. Background technique [0002] The power supply reliability rate reflects the power grid enterprise's ability to continuously supply power to users, and directly reflects the high-quality service level of the enterprise. It is particularly important to shorten the repair time of power outages and improve service quality. In order to grasp the operation data of the power supply situation of power users in a timely manner, the State Grid Corporation of China has started the construction of an electricity consumption information collection system. In 2015, the State Grid Corporation of China plans to invest 420.2 billion yuan in the construction of power grids, a year-on-year increase of 24%, and the investment amount has reached a record high. Among them, 60.6 ...

Problems solved by technology

[0003] With the construction of such a large-scale power consumption information collection system, the power company needs to fully understand the power consumption situation in the area under its jurisdiction, and deal with the impact of abnormal power outages and power-on on the reliability of power supply in a timely manner; however, due to the aging of power supply equipment, or the user Irregular operations, etc., will lead to different ranges of abnormal power outages and power-on situations. Therefore, how to detect the above situations in a timely manner, minimize the impact of abnormal power-on and power-off on power users, shorten the time for power outage repairs, and improve work. Efficiency, providing basic data for distribution network operation monitoring, is a very urgent demand for provincial power companies

[0004] At present, there is no overall plan or unified technical principle for power outage detection in medium and low voltage distribution networks in China. Most of the special transformers, public transformers, power outages in station areas, and power outages in lines are still informed by on-site personnel on duty or users by calling. There is no special means for real-time monitoring of power outages in the distribution network, which increases the response time and repair time of power outages, and reduces the reliability of power supply
