Power flow calculation realization in software for grids with four-phase power lines

摘要

The paper is devoted to the problem of power flow calculation and steady state analysis methods adaptation to four-phase electrical grids. These methods are based on developed models of four-phase power lines and phase convering transformers. The basis of research is nodal voltages equations for three-phase, four-phase and mixed (combined by three- and four-phase elements) grids. Algorithm of four-phase element parameter automized adaptation for power flow calculation model "RastrWin" software has been developed.
