Abstract

The present invention provides a method and device for selecting a distribution network power supply reliability improvement scheme, by constructing a reliability evaluation model, that is, establishing a functional relationship between the key data of the reliability improvement scheme and the reliability improvement scheme, and drawing a Pareto curve , and combine the constraints to coordinate the reliability and economic optimization, and quantify the reliability evaluation results to obtain the specific values ​​of various reliability improvement schemes, which can intuitively evaluate the input and output of various reliability improvement schemes The situation, so as to select the reliability improvement plan with the best economic benefits. The method and device provided by the invention can quantify the input and output of the distribution network power supply reliability improvement scheme in combination with the actual constraints, and provide the selection method of the reliability improvement scheme from the perspectives of reliability and economy, which is scientific and reasonable sex.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for selecting a power supply reliability improvement scheme of a distribution network. Background technique [0002] With the rapid development of my country's power grid construction, the reliability improvement scheme of distribution network power supply is of great significance to the quality of power supply, and the reliability and economy of distribution network power supply must be taken into account at the same time. However, in most power supply enterprises at present, there are often problems such as distribution network power supply reliability improvement schemes regardless of investment costs, reliability improvement schemes lacking economic rationality, limited space for reliability improvement, and low reliability investment input-output ratio. [0003] The selection method of distribution network power supply reliability improvement sche...
