Embodiment approach

[0024] As an embodiment of the present invention, the power grid operation data obtained by the data analysis module according to the prediction model analysis is called predicted data; the real power grid operation data actually collected by the data acquisition module is called collected data; the forecast The data and collected data are independently stored in the data storage module in chronological order; the data analysis module compares and analyzes the collected data, and the obtained model is a prediction model; the data analysis module compares and analyzes the predicted data to obtain Correct the model; the data analysis module compares and analyzes the prediction model and the correction model to obtain an unoptimized difference value between the two; the data analysis module reversely performs a reverse operation on the prediction model based on the obtained unoptimized difference value Correction and iteration; the data analysis module obtains optimized forecast d...

Abstract

The invention belongs to the technical field of power system monitoring, and particularly relates to a power grid operation state monitoring system based on big data, which comprises a data acquisition module, a data analysis module and a data storage module, the data acquisition module comprises an acquisition unit used for acquiring state data at a power grid operation node, after the data acquisition module acquires state data, the data is uploaded to the data analysis module through a 5G network, the data analysis module is used for analyzing the received state data by adopting a flow calculation mode and establishing a prediction model according to the received state data, the data analysis module analyzes the prediction model, predicts the operation state of the power grid in a shorttime in the future to obtain predicted operation data, and performs early warning on possible abnormal operation of the power grid in advance, the data acquired by the data acquisition module is stored in the data storage module, and abnormality can be discovered in advance and early warning can be performed so that operation safety of the power grid can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of power system monitoring, in particular to a big data-based power grid operating state monitoring system. Background technique [0002] With the construction of UHV power grids and the rapid development of new energy sources, major changes have taken place in the operating characteristics of power grids. The online monitoring and fault diagnosis methods of power grid equipment status based on traditional data processing technology can no longer meet the development requirements of the integrated operation of extra large power grids. At the same time, with the improvement of power grid collection and monitoring capabilities, the grid operation history data, SCADA data, and status monitoring data stored in the main station of the smart grid dispatching control system show a variety of data forms, large volume, multiple dimensions, and low value density. Such as the characteristics of big data, how to use big...
