Equipment transaction-based power distribution network reliability economic benefit analysis method

Abstract

The invention relates to an equipment transaction-based power distribution network reliability economic benefit analysis method. By obtaining transaction information of power supply region equipment, investment cost is calculated; reliability investment is matched with a pre-arranged power failure event to obtain an association relation; according to the transaction information, a power distribution network reliability improvement prediction model and a power distribution network reliability investment economic benefit calculation model before and after the reliability investment are established; and when the power supply region equipment is in transaction, the power distribution network reliability investment benefit calculation model is adopted to calculate the power distribution network reliability investment benefit. By virtue of the technical scheme, the problem in investment data source in the power distribution network reliability economic benefit analysis, and the problem existing in solving power distribution network reliability improvement amount from historical power failure and reliability investment data from the macroscopic aspect can be solved; meanwhile, a comprehensive power distribution network reliability economic benefit analysis model is established, so that influence of power distribution network investment to power distribution network reliability can be reflected more accurately.

Description

technical field [0001] The invention relates to an economic benefit analysis method, in particular to a distribution network reliability economic benefit analysis method based on equipment abnormalities. Background technique [0002] Studying the calculation and evaluation methods of distribution network reliability investment economic benefits is beneficial to power grid companies according to different reliability investment economic benefits generated by different investment levels, and to analyze the positive benefits, negative benefits, and comprehensive benefits of different distribution network construction and transformation. Evaluation and assessment. [0003] In order to establish a distribution network reliability investment benefit analysis model, reliable distribution network reliability and economic data sources are needed. At present, in the process of reliability management, power grid enterprises will record information such as the time of the power outage ...
