Information grade determination method and device, computer equipment and storage medium

Abstract

The invention relates to an information grade determination method and a device, computer equipment and a storage medium. The method comprises the steps of obtaining at least one piece of initial index data of a transformer substation in a preset time period, and determining an upper-level classification index corresponding to each piece of initial index data; determining a subjective weight and an objective weight of each piece of initial index data according to an upper-level classification index corresponding to each piece of initial index data; determining a comprehensive weight of each initial index data according to the subjective weight, the objective weight and an optimization decision model; and according to the comprehensive weight, determining the importance level of each piece of initial index data. By adopting the method, the alarm information of the primary equipment and the secondary equipment of the intelligent substation can be graded, subjective and objective conditions are considered, the grade division of the index data is more reasonable, and a worker can conveniently process related data information according to the importance degree and maintain the primary equipment and the secondary equipment of the substation.

Description

technical field [0001] The present application relates to the technical field of smart grid, in particular to a method, device, computer equipment and storage medium for determining information level. Background technique [0002] With the establishment of the "big operation" system of the State Grid Corporation of China, the intelligent substation has realized the operation and management mode of unattended and centralized monitoring. The monitoring information of the substation is all collected in the dispatching control center. Faced with a large amount of alarm information, the operation and maintenance personnel have a heavy workload in information analysis and processing. Important information alarms cannot be found in time or missed monitoring occurs from time to time, resulting in the operation and maintenance personnel not being able to find out in time Key failures will not only cause economic losses, but also have a great impact on the safe and stable operation of...
