An optimal maintenance method for 10kv distribution transformers considering the risk of power grid operation

Abstract

The present invention is a 10kV distribution transformer optimization maintenance method considering the operation risk of the power grid. The method includes: calculating the failure rate of the 10kV distribution transformer; calculating the individual risk loss of the 10kV distribution transformer maintenance and the risk loss of the power grid operation; The objective function of transformer maintenance and the corresponding constraints; complete the optimal maintenance of 10kV distribution transformer. The method for optimizing the maintenance of 10kV distribution transformers provided by the present invention, which considers the operation risk of the power grid, improves the operation, maintenance and maintenance level of the distribution transformers, prevents and reduces the probability of failures, and reduces the waste of maintenance resources.

Description

technical field [0001] The invention relates to a maintenance method, in particular to an optimized maintenance method for a 10kV distribution transformer considering the operation risk of a power grid. Background technique [0002] The operating state of distribution transformers plays a very important role in the safety and stability of distribution network. Once a distribution transformer fails, it will bring huge losses to the power grid and equipment assets, and the resulting power outages and impact on the normal order of society will cause huge economic losses, and at the same time will bring serious negative impacts on society. [0003] The existing distribution transformer status evaluation and maintenance strategy formulation often formulate maintenance strategies from the equipment level, focusing on the individual performance of the equipment, and less consideration is given to the overall operation performance of the power grid. From the perspective of individu...

Problems solved by technology

From the perspective of individual equipment behavior, although the maintenance decision based on the individual performance of the equipment is conducive to improving the performance of its individual operation, due to the contradiction between the shortage of distribution network operation and maintenance resources and the huge number of equipment, there will inevitably be conflicts between the individual and the whole. Contradictions and conflicts, thereby reducing the efficiency of the overall operation of the distribution network
