Power grid fault early warning method and system, electronic equipment and storage medium

The embodiment of the invention provides a power grid fault early warning method and system, electronic equipment and a storage medium, and belongs to the field of power grid safety. The method comprises the steps that operation data of a to-be-detected power grid are collected, and the operation data at least comprise voltage, current, a power factor and a temperature parameter; the operation data of the to-be-tested power grid are input to a pre-constructed prediction model, a prediction result is obtained, early warning is carried out according to the prediction result, and the pre-constructed prediction model is constructed based on a BP neural network. According to the technical scheme, through the prediction model pre-constructed based on the BP neural network, the collected operation data of the to-be-tested power grid is deeply analyzed, the prediction result is determined, and early warning is performed according to the prediction result, so that the power grid monitoring efficiency is improved, real
