According to the principle of short circuit calculation for distribution network, the distribution network topology analysis and short circuit calculation are designed and implemented in this paper, and the implementation is based on the object-oriented technique. The backward/forward method based on the superposition theorem is adopted in short circuit calculation, and the branch layering method is used in the topology analysis. The combination of two methods guarantees the efficiency of short circuit calculation algorithm. Moreover, the object classes based on the object-oriented technique are designed to implement the short circuit 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.
