摘要： Provided is a distributed-power-generation system capable of maintaining an operation point and a method of controlling the same. The distributed-power-generation system comprises: a fuel cell producing current and high-temperature gas through an electric chemical reaction of hydrogen and oxygen; a turbine obtaining rotation power using heat produced by the fuel cell; a compressor supplying air to the fuel cell using the rotation power of the turbine; a motor/generator unit acting as a motor using a current supplied from a battery in a starting mode, and as a generator rotating by rotation power of a turbine and generating a current in a generating mode; and an inverter unit supplying a DC power produced by the fuel cell and an AC power produced by the motor/generator unit for a three-phase power system. The method of controlling the distributed-power-generation system comprises: sensing a rotation speed of a rotation axis of the motor/generator unit; comparing the sensed rotation speed and a predefined reference speed; and supplying a current to the motor/generator unit to produce a load in the opposite direction of rotation of the rotation axis or in the same direction.
