摘要：

This paper presents a uniform algorithm for single-phase and three-phase load flow calculation. Firstly, two iterative equations with static factors are studied for single-phase power flow calculation based on Gauss power flow algorithm. One is used for all PQ nodes iteration similar to the traditional Gauss power flow algorithm, and the other one is exploited for all PV nodes and the slack node, which is a new algorithm studied in this paper. Then, the three-phase power flow iterative equations are studied. Virtual generator nodes are generated so that it is enough to built equations to solve the unknown parameters and each equation has a unique solution. Two iterative equations are studied for three-phase power flow calculation based on the single-phase formulation studied in this paper. The calculation result shows that the algorithm has the advantage of fast calculation speed, reliable convergence and powerful applicability. It has been shown that the algorithm is suitable for online calculation of single-phase and three-phase power system.
