摘要： PROBLEM TO BE SOLVED: To provide a power supply unit suited for a power supply system that performs parallel operation of a plurality of unitized power supply devices, formed from generators and power converters. SOLUTION: This power supply device includes a generator, a power converter for converting power generated by the generator into AC power at a required frequency and voltage, and a controller for the power converter. The controller is provided with a control section with output voltage-output current characteristics for determining the output voltage, corresponding to the output current of the power converter. The output voltage-output current characteristics include a first drooping characteristic for limiting the output power of the generator between a first output current that exceeds the generation capacity of the generator and a second output current beyond the conversion capacity of the power converter.

摘要： PROBLEM TO BE SOLVED: To provide a gas turbine power generator capable of stably supplying power to a load even in a power failure. SOLUTION: The gas turbine power generator includes a generator 3 to be driven by a turbine 1; a reverse conversion device 4 for converting the output AC power of the generator into a commercial AC power; a first breaker 7 for connecting and disconnecting the turbine power generator and a commercial power supply system; a second breaker 8 for electrically connecting and disconnecting a load 40 to an output line 10 extending from a branch point between the first breaker and the reverse conversion device; a switch 9 provided between the reverse conversion device and the first breaker; a power failure detector 25 provided between the first breaker and the commercial power supply system 30; and a control section 22 for controlling the operation of the turbine power generator. In a stationary state, the first breaker and the second breaker are closed so that a load is supplied with power from the turbine generator and the commercial power supply system, and in power failure, the first breaker is opened to separate the turbine generator from the commercial power supply system so that the load is supplied with power from the reverse conversion device.
