要約(英語): From the global environmental viewpoint, distributed power systems using renewable energy source, such as solar power, wind power, and water power attract much attention. Photovoltaic (PV) system using solar power has a little resource constraint and can be installed easily on the roof of house. Therefore, PV system has been and will be introduced widely. However, in case many PV systems are installed in consumers, the deference of installed PV capacity may cause the load unbalance. In such a case, the difference of the line currents flowing along middle / high-voltage lines can be increased and three-phase voltage unbalance may appear due to the line impedance.In this paper, a distribution transformer using three-phase to single-phase matrix converter with an AC inductor is proposed to suppress three-phase voltage unbalance. The AC inductor is used for compensation of single-phase power pulsation at any load conditions and either direction of power flow. The proposed method is verified by the simulation with MATLAB/Simulink. In this simulation, the resistive loads and the reactive loads are assumed as the loads in low-voltage line. Reverse power flow from PV systems is represented by a current source with power factor 1.0. Control strategy and simulation results are shown in this paper.
