Abstract
Relatively independent evaluation parameters are selected from many parameters through pedigree clustering.Learning the analytic hierarchy process (ahp) and entropy weight method can determine the weight, and at the same time to understand the error of the analytic hierarchy process (ahp) and entropy weight method is large, so the combination of the subjective and objective weight obtained by the two methods, using the improved entropy weight-ahp method to determine the weight. The improved weight calculation method has a clear hierarchical structure, which not only considers the influence of subjective and objective factors, but also makes full use of the weight information in the hierarchical structure. Considering the uncertainty of information, gray relation is adopted to deal with the data, so as to make maintenance rules.
Highlights
Combining the experience in power grid maintenance work site, repairing the power grid requires timeliness, in excess of the prescribed time limit to repair unfinished tasks, will be the inspection, repair often run a day when many substation hair stand, but still can't finish the repair, especially in the summer peaks, flood control and buy electric and other major electrical tasks, requirements to repair timely. the society needs to ensure the stability of electric energy, so, when the failure occurs, need to complete the repair task within the deadline, overdue, repair personnel will be assessed.it is very important to put forward a more scientific and effective state maintenance scheme to reduce the operation cost of power grid and improve and ensure the power quality.Table 1
Electric energy has been widely used in every industry, production and living of human society into the age of electricity power is the most important in the modern society is the most convenient sources of energy, are the tools of scientific development to transfer production distribution and consumption of electricity power system of electric equipment
If the relay protection system is defective, it may affect the reliable operation of the system
