Optimization strategy of operation and maintenance based on econometric model

With the continuous development of power grid, the investment of equipment assets is increasing sharply during the 13th Five Year Plan Period. There is a growing need for equipment maintenance as the equipment ages and varies in different types from transmission to distribution equipment. Equipment is the base element of healthy power grid development. Therefore, it is important to raise the efficiency and quality of equipment status via operation and maintenance. To improve the effectiveness of equipment maintenance, reduce the maintenance cost, improve the safe operation level and power supply reliability of power grid, this paper uses econometric model of correlation analysis to build the correlation between daily overhaul, operation and maintenance and fault frequency and voltage qualification rate, so as to provide optimal decision for the development of operation, inspection and maintenance of power grid company.
