Load Supply Capability Based Analysis of HV Distribution Network Connection Mode
摘要
Abstract
In traditional connection mode analysis of high-voltage (HV) distribution network the features of different connection modes are assessed in two aspects respectively, namely the economy and the reliability, however the isolating economy from reliability makes the assessment results not comprehensive and rational. To make supplement to traditional connection mode analysis, utilizing the concept of load supply capability and considering the correlation between the economy and the reliability, typical connection modes of HV distribution network are analyzed and compared. Firstly, a load supply capability model, in which the“N-1” contingency of HV distribution line is considered, is proposed and corresponding solution is given; secondly, the boundary conditions for the analysis and computation is established and applying the proposed load supply capability model to four typical connection modes of HV distribution network; finally, the results of both calculation and analysis show that theπ-shaped connection mode not only possesses higher reliability but also it possesses advantage in economy, then the economic capacity single line under T-shaped connection mode is given to guide the selection and application of connection modes for HV distribution network.关键词
