Embodiment Construction

[0039] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered below.

[0040] like figure 2 As shown, a preferred embodiment of the present invention provides a method for synchronizing cycle-level power data, including the following contents:

[0041] Step S1: obtaining cycle-level data sequences of two nodes on the same power supply cable;

[0042] Step S2: setting a sliding window, the sliding window includes a left data area and a right data area of ​​equal width;

[0043] Step S3: Use the sliding window to slide in the cycle-level data sequences of the two nodes respectively, and calculate the Pearson coefficient between the data curve in the left data area and the data curve in the right data area every time you slide, so as to obtain sequence of Pearson coefficients for two nodes;

[0044] Step S4: obtaining the ...

Abstract

The invention discloses a cycle-level power data synchronization method and system, equipment and a storage medium, the synchronization method adopts a Pearson coefficient change value to perform matching calculation, the larger the Pearson coefficient change value is, the larger the correlation change between data curves of left and right data areas of a sliding window is, and in the actual situation, for one node, the correlation change between the data curves of the left and right data areas of the sliding window is, and the correlation change between the data curves of the left and right data areas of the sliding window is. The probability of mutational influence in dozens of cycles is very small, so that when the window slides, the correlation between the data curves of the left and right data areas of the front and back windows is not greatly changed in most cases, namely, the Pearson coefficient is not greatly changed in most cases; according to the method, the time when the Pearson coefficient change value is large and less occurs is selected for waveform synchronization, good exclusiveness is achieved in time selection, the influence of errors can be effectively eliminated, the synchronization accuracy is improved, and the synchronization time is shortened.

Description

technical field [0001] The present invention relates to the technical field of power data synchronization, and in particular, to a method and system for synchronizing power data at a cycle level, an electronic device, and a computer-readable storage medium. Background technique [0002] At present, the highly intelligent power grid puts forward higher requirements for data. It is necessary to further improve the data breadth and data depth. In terms of breadth, it is necessary to apply more dimensional data, such as increasing meteorological data, geographic information data, electricity market data, etc. In terms of depth, higher frequency and higher synchronization power measurement data, such as 20ms cycle-level data, is required to provide more detailed, richer and more accurate data features. At present, the data of the power grid is mainly minute-level data. With the improvement of the intelligent level of the power grid, more and more intelligent applications will use...
