碩士 === 崑山科技大學 === 光電工程研究所 === 107 === In order to solve the problem of feeder loss in medium voltage distributed system. This article will use the sample MV distribution network project of DIgSILENT software as an example. To simulate and optimize the loss of low-voltage distributed grid feeders. Feeder-loss will cause transmission efficiency to decrease. Reducing energy efficiency can cause serious damage to equipment. This article will be carried out in a way that optimizing the switching section of the distribution network. We will discuss the feeder-loss values before and after optimization. This article present two assumptions. Hypothesis one: After urban and suburban were optimizated. Because the urban feeder is denser, the receiving end is closer to the substation, and the feeder loss is smaller. On the contrary, the receiving end of the suburb is so far from the substation that the loss is larger. It may be more economical to optimize the feeder switch of the suburbs. Hypothesis two: The results of Tie Open Point Optimization may have undesirable values. Whether it is related to feeder distribution and substation is the problem that this article will explore.
