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...
