摘要： A power converting apparatus, in which when a single-sustained operation is switched into a linkage operation in a combined power generation system such as a microgrid, a control system does not have to be changed, is provided. The apparatus includes a first internal phase difference angle calculator (60) for integrating a deviation between a first frequency command value and a frequency obtained by a frequency obtaining device (14) so as to calculate a first internal phase difference angle, a first internal electromotive voltage command value calculator (50) for proportioning and calculating a deviation between a first reactive power command value and a reactive power obtained based on the value measured by the first measuring device (3, 4), and adding a reference voltage to the deviation so as to calculate a first internal electromotive voltage command value, and a first current command value calculator (70) for calculating a command value of an output current from a first power converter (6) based on the first internal phase difference angle, the first internal electromotive voltage command value, and a voltage measured by the voltage measuring device (4). The apparatus controls the first power converter (6) based on an output from the first current command value calculator (70).
