Abstract�� The topological structure is one of the key factors affecting the reliability performance of the electrical power system (EPS) in more electric aircraft (MEA). A topology analysis method was adopted to build a universal algorithm of reliability evaluation. Qualitative results could be obtained through this method. Faults tolerance ability of EPS in MEA was focused in the analysis process. Quantitative indices was obtained through euclideandistance and entropy calculation of the analysis results in the evaluation process. Based on this reliability evaluation platform, qualitative analysis and quantitative indices calculation of different aircraft topological configurations were experienced using a sample system data. Result shows that the reliability level of redundancy power network is better than others and it is the basical configuration prototype of future aircraft power networks.
Keywords�� more electric aircraft   electrical power system   topological configuration   reliability
