Design method for intelligent monitoring center system of high-voltage cable

Abstract

The invention discloses a high-voltage cable intelligent monitoring central system design method, which continuously collects cable partial discharge data and updates a partial discharge recognition model training sample library through a high-voltage cable partial discharge mode recognition model integrated in a web central system based on evolutionary learning and a convolutional neural network, thereby improving the cable discharge type recognition precision. Meanwhile, multi-type parameters of the cable are recorded, a cable state multi-parameter evaluation model is established through a multi-parameter evaluation and fuzzy comprehensive evaluation method, and then the cable state multi-parameter evaluation model is established through a data management module, a data communication module and a data visualization module based on a Web central system. And performing mode identification and state evaluation on the state of the in-operation cable, generating a diagnosis report, giving an integrated detection and evaluation process of cable maintenance suggestions, and completing cable state evaluation and operation and maintenance guidance. According to the method, multiple artificial intelligence methods are integrated in a high-voltage cable monitoring center system, and the cable state can be monitored in real time in the online operation state of the cable.

Description

technical field [0001] The invention relates to a design method of a high-voltage cable intelligent monitoring central system, and belongs to the field of cable localized online monitoring. Background technique [0002] With the continuous increase of urban electricity demand, the proportion of high-voltage cables put into use in urban power transmission and distribution is increasing year by year. The operation status of high-voltage cables directly affects the stability of the entire power transmission and distribution network. [0003] With the increase in the service life of cables, more and more cables in operation are gradually shortened in service life, and the insulation performance of cables is reduced. However, the current cable safety inspection is mainly carried out offline, which will cause certain economic losses and inconvenience to people's lives and industrial development. It is imminent to develop online monitoring equipment for high-voltage cables on site....
