RESUMO

This work proposes a parallel three-phase power flow method for asymmetrical distribution systems, based on the Zbus Gauss method. Ali the elements of the distribution systems are modeled using per phase quantities and the I = YV formo Moreover, the component models are phase decoupled by using compensation current injections, making the method suitable for parallel computing, since the equations of each phase can be solved independently. The modeling includes asymmetricallines, three-phase lossy transformers, capacitors, cogenerators and unbalanced loads. In order to evaluate its performance, the method was implemented in serial machines, in the parallel computer nCUBE2, in a workstation network with PVM, and the results were compared with that showed by the serial Zbus Gauss method using several real distribution networks. It was observed a speedup of 2.82 using three processors in comparison with the serial Zbus Gauss method. The developed program can be applied to three-phase distribution systems operation and planning analysis, allowing some important characteristics to be studied: transformers and lines losses, radial and meshed configurations, unbalanced loads, loading variation, effects of transformers winding connections and effects of cogenerators and shunt capacitors
