Abstract

The invention discloses a state maintenance method for secondary equipment of a power grid. The method comprises the following steps of: establishing a maintenance model: establishing a state maintenance model comprising a plurality of assessment items and a maintenance strategy for the secondary equipment in a management information system, wherein each assessment item comprises at least one assessment index; evaluating an equipment state: acquiring online and / or offline data information of the assessment index of each assessment item in the state assessment model of the secondary equipment to be detected from the management information system and evaluating the state of the equipment according to the data information; and making a maintenance scheme: making a maintenance scheme of the equipment according to a state evaluation result of the equipment and the maintenance strategy in the state maintenance model. The invention further discloses a corresponding state maintenance device for the secondary equipment of the power grid. According to the method and the method, the investment and maintenance costs of the secondary equipment of the power grid can be reduced greatly.

Description

technical field [0001] The invention relates to the field of power system automation, in particular to a state maintenance method and device for secondary equipment of a power grid. Background technique [0002] Power supply equipment and systems are becoming more and more intelligent and complex, and the maintenance requirements for power supply equipment are getting higher and higher. Equipment maintenance costs have gradually become a major cost of power supply companies from a relatively small share at the beginning. With the in-depth reform of my country's power system and the implementation of "separation of factories and grids, and bidding for the Internet", power companies will face the pressure of reducing costs and improving competitiveness. At present, electric power enterprises implement a maintenance system based on planned maintenance. This maintenance system ensures the planning of manpower, material resources and funds, and maintains the basic stability of p...
