Abstract

The invention discloses a power grid equipment operation automatic comparison method, which comprises the steps of (1) calculating an original data matrix M according to evaluation index data; (2) performing standardization processing on the index data to obtain a standardized decision matrix (Pij)m*n; (3) calculating a combination weight omega j by using an entropy weight-AHP combination method;(4) calculating index weighted evaluation matrix values V according to the combined weight omega j; and (5) sorting the index weighted evaluation matrix values, wherein the comprehensive performance of power grid equipment assets is in direct proportion to the index weighted evaluation matrix values. According to the method, the operation state of power grid equipment can be accurately mastered, potential problems of the equipment are found through trace tracking, and the technical problems of equipment management such as equipment operation, maintenance and overhaul are improved to a great extent.

Description

technical field [0001] The invention belongs to the technical field of distribution network equipment operation. Background technique [0002] With the promotion and application of distribution automation technology, distributed power sources and a large number of diversified loads, the intelligent technology of distribution network has developed rapidly, and intelligent planning has gradually become an indispensable and important content of distribution network planning. . At present, although the power supply reliability level of my country's distribution network has been significantly improved, the overall development level is still relatively weak, and the urban-rural and regional development levels are not balanced. With the continuous improvement of urban power supply reliability requirements, the deepening of new urbanization, and the influence of many external conditions such as distributed power supply and diversified load access, how can we find out through the da...
