Transmission line malfunction early-warning method and system based on big data driving

Abstract

The invention discloses a transmission line malfunction early-warning method and a system based on big data driving. The transmission line malfunction early-warning method comprises the following steps: acquiring related information of a power transmission line, wherein the related information of the power transmission line comprises electricity quantity, meteorological data, malfunction even sequence information and power grid topological data; extracting characteristics of the related information of the power transmission line, and furthermore establishing a malfunction factor mining databank and a malfunction judgment characteristic bank; based on a Naive Bayes algorithm, performing malfunction factor index mining on data in a current malfunction factor mining databank, and furthermore performing abnormal state tracking on an abnormal malfunction factor; transmitting the malfunction factor index of the abnormal malfunction factor to the malfunction judgment characteristic bank, matching an early-warning information time sequence generated in real time inside the malfunction judgment characteristic bank with a preset malfunction standard time sequence on the basis of a time sequence similarity malfunction matching method, outputting early-warning information corresponding to the matched early-warning information time sequences, and performing early-warning of malfunctions.

Description

technical field [0001] The invention belongs to the field of intelligent electricity utilization, and in particular relates to a transmission line fault early warning method and system driven by big data. Background technique [0002] With the development of society and economy, the dependence on electricity is getting stronger and stronger. Large-scale power outages often start from the failure of a certain line of the power grid, and continue to expand with the strong correlation and vulnerable links of the power grid topology. For some areas with weak power grids, a single line failure may lead to load loss. [0003] At present, most of the related research on transmission line faults only relies on existing data to diagnose faults. In fact, power systems have problems such as single uploaded data, large quantities, and poor comprehensiveness, which makes it difficult to achieve fault prediction relying on such data. Comprehensive and forward-looking, poor information re...

For some areas with weak power grids, a single line failure may cause load loss

[0003] At present, most of the related research on transmission line faults only relies on existing data to diagnose faults. In fact, power systems have problems such as single uploaded data, large quantities, and poor comprehensiveness, which makes it difficult to achieve fault prediction relying on such data. Comprehensiveness and forward-looking, poor information response timeliness, and it is difficult to do a good job of tracking and predicting the development trend of line abnormalities
