Modularized risk prediction method and device for power distribution terminal and storable medium

Abstract

The invention discloses a modularized risk prediction method and device for a power distribution terminal and storable medium, According to the invention, each working module in the power distributionterminal is used as a prediction object; obtaining operation and maintenance index data according to the obtained operation and maintenance index data; risk probability values of all working modulesof the power distribution terminal are obtained through an entropy weight method, then the overall reliability prediction value of the power distribution terminal is obtained through an upper limit method and a lower limit method according to the risk probability values of all the working modules, and the technical problem that an existing risk prediction method with the overall power distributionterminal as a unit is large in error is solved.

Examples

Embodiment Construction

[0049] Embodiments of the present application provide a modularized risk prediction method, device and storage medium for power distribution terminals, which are used to solve the technical problem of large errors in existing risk prediction methods based on the entire power distribution terminal.

[0050] Information entropy was first introduced by Shannon into information theory, and it has been widely used in engineering technology, social economy and other fields. The entropy weight method determines the objective weight according to the variability of the index. Generally speaking, if the information entropy of an index is smaller, it indicates that the value of the index varies more, the more information it provides, the greater the role it can play in the comprehensive evaluation, and the greater its weight. On the contrary, the greater the information entropy of an indicator, the smaller the variation of the indicator value, the less information it provides, the smaller...
