Problems solved by technology

[0005] To this end, the embodiment of the present invention provides an edge computing method for real-time analysis of low-voltage branch topology based on PV relationship. By using wavelet packet to denoise the signal, the EMD algorithm is used to decompose the IMF components representing different time scales, and the As a feature vector input into the edge computing entity model, it can accurately and effectively judge the location of the low-voltage line loss and its value, and at the same time ensure a very high recognition rate, so as to solve the problem that the collected data needs to be stable at a certain convergence in the prior art domain, and the relevant convergence threshold cannot be balanced, resulting in the relatively difficult problem of calculating the line loss

Abstract

The invention discloses an edge calculation method for low-voltage branch topology real-time analysis based on a PV relationship. The method comprises the following steps: S01, acquiring voltage and current signals of a transmission cable, performing wavelet packet denoising processing; S02, performing EMD decomposition on the signals to obtain a plurality of IMF components, and using a normalization algorithm to obtain an EMD energy entropy as a feature vector; S03, establishing a credible model based on the edge computing entity according to the feature vector; S04, performing credibility evaluation on the edge computing entity by adopting an analytic hierarchy process, and computing comprehensive credibility; S05, calculating low-voltage information through EMD energy entropy, and converting identification of the current signal into identification of a fault position feature vector; and S06, performing classification detection on the test samples of the fault position feature vectors so as to detect whether the signals are fault low-voltage signals or not, so that the low-voltage line loss positions and the numerical values thereof can be accurately and effectively judged, and meanwhile, an extremely high recognition rate is ensured.
