[Abstract]:Taking the relay protection device of the whole power system as the research object and combining the characteristics of the relay protection equipment, the paper is planned and designed in order to ensure the safe operation of the equipment as the first principle to choose the maintenance management strategy of the relay protection. In this paper, the research trends of strategy selection in the maintenance management of relay protection devices at home and abroad are analyzed and introduced in detail, and the present situation and existing problems of the maintenance of relay protection devices in China are analyzed. The causes of maintenance management in domestic relay protection maintenance management are analyzed. This paper focuses on the importance of strategy selection in maintenance management of relay protection devices in high and low voltage relay protection maintenance, and introduces and summarizes the overall thinking of strategy selection, fault detection and evaluation, and status identification. Combined with the actual analysis method, the status quo and the existing problems of the maintenance of relay protection equipment are analyzed in this paper, and the current situation and the existing problems of the maintenance of relay protection equipment are described. This paper demonstrates the accident types of relay protection equipment in the past 3 years in a 110kV power station, using accident flow chart, cause and effect analysis table, column chart, accident type statistic table and strategy analysis tree method, respectively. In this paper, the importance of strategy selection in maintenance management of relay protection device is statistically summarized, and the strategy selection and cause analysis are carried out with these analysis methods, and it is clear that the strategy selection of relay protection device maintenance management is very clear. The statistical reasons and types of accidents are given intuitively, and the theoretical analysis and empirical analysis are given to the strategy selection in the maintenance management of relay protection devices in power system. It provides a reference for the condition-based maintenance of relay protection and the normal operation and maintenance of power system. In this paper, the overall idea of strategy selection in the management of relay protection maintenance in power system is planned and introduced, and the fault detection and evaluation of relay protection device maintenance in power system as well as the status identification of maintenance are introduced in detail. The maintenance strategy of relay protection is analyzed and optimized, and the accident flow chart, cause and effect analysis table, column chart and accident type statistic table are used respectively. The strategy selection of relay protection device maintenance in power system is studied by means of strategy analysis tree method and other methods.
