摘要： Disclosed is a variable-speed power generation device that ensures a speed-variability range for a wound-rotor induction generator while supplying reactive power in response to reactive-power supply commands from a power system. The disclosed variable-speed power generation device (1) is provided with: a prime mover that utilizes natural energy to generate power; a power generator (6) that generates electricity from the power generated by the prime mover and has a stator, provided with a first winding connected to a power system (2), and a rotor, provided with a secondary winding; a power converter (17) connected to the stator side and the rotor side; and a power converter controller (21). The power converter (17) does not supply reactive power to the power system (2), and when a reactive-power supply command that causes reactive power to be supplied to the power system (2) is received from the power system (2), the power converter controller (21) runs the power generator (6) at a speed set greater than or equal to the synchronous speed, thereby increasing the reactive power supplied to the power system (2).

摘要： An object is to prevent a situation in which, when a change in the frequency of a utility grid is to be recovered from, an increase or decrease in the generated output power becomes excessive, thus making a wind turbine generator unable to supply electrical power to the utility grid. A wind-curbine control device controls a wind turbine generator in which a rotor having a plurality of blades receives wind and rotates, a generator generates electrical power through the rotation of the rotor, the electrical power is supplied to a utility grid, and electric energy to be supplied to the utility grid can be changed according to a change in the frequency of the utility grid. A subtracter (62) of the wind-turbine control device calculates a frequency change, which is the difference between a measurement value of the frequency of generated output power of the wind turbine generator and a set value of the frequency of the generated output power of the wind turbine generator, and a limiter (66) limits a change in the electrical power corresponding to the frequency change calculated by the subtracter (62), based on the rotational speed of the generator.
