摘要： In a wind turbine generator, the rotation of the rotor is speeded up by a hydraulic pump and a hydraulic motor and is transferred to a synchronous generator. In a state in which the wind turbine generator is interconnected to a utility grid, and the synchronous generator reaches a synchronous speed, if no mechanical power is transferred to the synchronous generator, a wind-turbine control system operates the synchronous generator as a synchronous condenser, thus controlling the magnitude of the field current of the synchronous generator. Thus, the wind turbine generator can supply reactive power to the utility grid without adding new equipment, such as a reactive power compensator using a semiconductor switch.

摘要： A wind-turbine control device controls a wind turbine generator in which a rotor having a plurality of blades receives wind and rotates. The 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. The wind-turbine control device includes a subtracter to calculate 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. The wind-turbine control device further includes a limiter to limit a change in the electrical power corresponding to the frequency change calculated by the subtracter, based on the rotational speed of the generator.

摘要： A wind power generator generates power through a rotation of a rotor and is interconnected, and operated with its power generation output previously limited in order to be able to further supply the power to a power system in response to a decrease in system frequency. Thus, a concentrated control system derives a required restricted amount corresponding to a power generation output required to respond to the decrease in system frequency, derives a value by subtracting an amount corresponding to a latent power generation output with which the power generation output can be increased, from the required restricted amount, and sets a restricted amount of the power generation output in each wind power generator to perform the operation with the power generation output previously limited to respond to the decrease in system frequency, based on the above value.

摘要： A variable-speed power generator includes a prime mover that generates motive power by using natural energy; a wound-rotor induction generator that includes a stator having a primary winding and a rotor having a secondary winding, which are connected to a power grid, the generator generating electric power based on the motive power generated by the prime mover; a power converter connected to the stator and the rotor; and a controller controlling wound-rotor induction generator. The controller responds to instructions, sent by the power grid, for supplying reactive power to the power grid. The response of the controller to an instruction for supplying reactive power to the power grid may include imposing limitations on the reactive power supplied by the power converter to the power grid and causing the wound-rotor induction generator to operate at a rotation speed set higher than or equal to a synchronous speed.

摘要： It is an object to stabilize a utility grid even when an unexpected fluctuation in the frequency of the utility grid occurs. A wind turbine generator includes a rotor that rotates by wind power, a generator that is driven by rotation of the rotor, and a control device that controls a power output of the generator to increase while a rotational speed of the generator decreases when a frequency of a utility grid becomes smaller than or equal to a predetermined rated frequency and when the rotational speed of the generator is greater than or equal to a first predetermined value. In this way, even when the frequency of the utility grid fluctuates, the frequency fluctuation can be suppressed, and the utility grid can be stabilized.
