Optimization strategy of operation and maintenance based on econometric model

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