Embodiment Construction

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] The present invention analyzes the data by collecting the running parameters of the distribution network automation switchgear, and finds out the failure cause, failure frequency and frequent failure accessory type of each manufacturer's equipment. By studying the correlation between them, we can identify the equipment performance differences of various manufacturers and provide a reference for later equipment procurement; by analyzing the equipment failure frequency of each manufacturer, remind the operation and maintenance department to maintain the existing equipment in time and replace the easy-to-fail accessories. ; By analyzing the causes of equipment failures of various manufacturers and mastering the types of accessories that are prone to failures of each manufacturer, it can provide a basis for the procurement of spare parts for th...

Abstract

The invention discloses a distribution network automation switch service life monitoring method based on power grid monitoring data, and the method comprises the steps: 1) collecting the operation parameters of all equipment in a power grid monitoring system, and building an equipment operation file; 2) putting the collected operation data of the equipment of each manufacturer into a sample set, and drawing a scatter diagram under the condition of the same operation time t by taking the abnormal opening and closing of all switches with defect faults as an X axis and taking the non-abnormal opening and closing as a Y axis; and step 3) data analysis: (1) judging a switch state according to a t / n value; (2) the smaller the t is, the more likely the switch of the manufacturer has defects; and (3) within a certain defect operation time t, the larger the X and Y values are, the more frequent the use of the switch within the same operation time is, and the better the performance is, namely, the point above the density trend line in the scatter diagram. The distribution network automatic switch operation data is used for monitoring the service life of the switch by adopting a data mining technology, and prediction and decision support is provided for power grid operation.

Description

technical field [0001] The invention relates to a method for monitoring the service life of an automatic switch of a distribution network based on power grid monitoring data, and belongs to the technical field of power distribution. Background technique [0002] At present, there are many manufacturers of distribution network automation switches, and the equipment conditions are complex. For example, accessories such as batteries and wireless modules frequently fail. These conditions lead to low equipment online rate, unstable operation, and remote control failure. The factors that cause frequent failures of distribution network automation switches are: 1. Frequent failures of accessories, such as batteries, communication modules, radio frequency devices, etc. 2. Frequent opening and closing, this shock load aggravates the capacity attenuation of the battery. 3. The motherboard CPU is easy to crash, and the motherboard runs slowly. 4. The communication module is frequently...
