要約(英語): This paper presents the experimental results of a grid connected inverter. The control of the inverter is based on the virtual synchronous generator model of algebraic type. In case of using the virtual synchronous generator model of algebraic type, there is no evidence for the satisfactory operation with unbalanced load and nonlinear load, because the generator model are constructed under the assumption that the load is linear and balanced. By choosing the feedback control loop gain appropriately, the satisfactory operation is achieved even if the unbalanced and nonlinear load is connected. Experimental results show that the power controls, active and reactive, are achieved preferably in grid connecting mode. Smooth transitions are also achieved from connecting mode to the island mode. The inverter can operate satisfactorily when the unbalanced load is connected. Harmonic analysis is done when a three-phase full-wave rectifier is connected as a nonlinear load. The harmonic current is supplied by the inverter and its output LC filter. It is shown that the harmonic current is supplied mainly by the inverter and that the voltage waveform is practically acceptable.
