Implementation of topology analysis and three-phase power flow for distribution systems

According to the principle of three phase power flow for distribution network,the distribution network topology analysis and three phase power flow are designed and implemented in this paper,and the implementation is based on the object oriented technique.The backward/forward method is adopted in power flow calculation,and the branch layering method is used in the topology analysis.The combination of two methods guarantees the efficiency of power flow algorithm.Moreover,the object classes based on the object oriented technique are designed to implement the power flow calculation.The performance test results of 33 nodes system and 123 nodes system and 292 nodes system are also offered in this paper,and the results indicate that the realized program has high efficiency.
