Abstract
The paper considers issues of increasing efficiency of multilevel power converter based on IGCT and IGBT modules to improve energy performance by compensating reactive power in electric networks. By the example of a local power grid using SEMIS SimulationTool design tool the results of calculations of variants of multilevel converters with IGCT and IGBT are presented. The study of possibilities to increase the efficiency of multilevel power converters (MPE) for reactive power compensation (RPC) in local electrical networks (LES) on the basis of plenipotentiary controlled semiconductor cells is of particular interest, because the efficiency of network operation is insufficient, especially in changing load modes with large electric power losses (PEM). And from these positions, one of the most effective tools are fast controlled (PFC) systems. For this purpose, research has been carried out to obtain the best results. Used in calculations tool and methodology are certified software products and algorithms of ABB-SEMIS Simulation Tool computer design.
