Evaluation Method of Relay Protection Status and its Application in Maintenance Decision Making
2018
With the in-depth reform of China's electric power system, the power enterprises will inevitably face the pressure of reducing costs and enhancing competitiveness. Improving the efficiency and efficiency of power equipment maintenance is a good way to reduce costs and enhance the reliability of power grids. The condition maintenance is based on the state monitoring and diagnosis technology. Through a certain state evaluation method, the current state of the equipment is judged, the failure trend of the equipment is foreseen and the mode of maintenance before the failure occurs. The relay protection equipment is the important equipment of the power system, and the research of its maintenance technology is less. The paper takes the state evaluation method of relay protection and its application in the maintenance decision as the main goal,and makes a more thorough research on the condition maintenance technology of the relay protection.
