Abstract: Reasonable selection of connection modes in medium-voltage distribution network will help to improve the comprehensive optimization level of distribution network. On the basis of the study of reliability and economy of the typical cable connection mode in Suzhou area, this paper proposed three kinds of selection methods of cable connection modes considering reliability and economy, including the reliability of absolute evaluation, comparative reliability increment and cost-benefit analysis of reliability. This paper used three methods to analyze the reasonable cable connection mode according to the local load growth situation in a commercial core area of Suzhou. The analysis results show that the three methods can ensure the reliability and fully improve the efficiency of resource utilization at the same time through comprehensive analysis.
Key words: medium voltage distribution network; typical connection mode; reliability; economy
