Abstract

The invention relates to an electric power system steady-state data compression method based on edge calculation, and the method comprises the steps: completing the steady-state data fusion of an electric power system under edge calculation through the stages of building a joint sparse model, building a sparse redundant dictionary, determining a measurement matrix, building a joint reconstruction algorithm and the like in combination with compressed sensing and distributed information source coding; and decomposing the obtained data fusion result to each scale level according to the resolution by utilizing a wavelet transform algorithm to obtain a high-frequency coefficient and a low-frequency coefficient, and outputting a compression result by adopting a lossless coding technology after processing the high-frequency coefficient through a threshold value. The steady-state data compression method is constructed in combination with an edge calculation method, the data of the power system are effectively compressed, and the storage space and the data transmission amount are reduced.

Description

technical field [0001] The invention relates to a method for compressing steady-state data of a power system based on edge computing. It belongs to the field of power grid technology. Background technique [0002] The national economy continues to rise, the scale of the power grid is growing day by day, and the power system is gradually developing towards diversification and complexity. Only by effectively recording massive power data can we meet the needs of power management and control such as data analysis, fault monitoring, and wide-area measurement. In this way, if you want to store and transmit large-scale data generated during the operation of the power system, it will greatly increase the operating speed and storage space burden, and even hinder the leapfrog intelligent development of the power grid. [0003] The power system is a key component of the grid enterprise. With the rapid development of society and science and technology, the degree of intelligence and ...
