Abstract
Wind power generating equipment includes: a generator that is driven by a blade which rotates by receiving the wind; a power converter that converts an electric output of the generator such that the output is interconnected with an electric power system; a power converter controller that controls the power converter; and a wind turbine control board that transmits, to the power converter controller, an active power command value that is used as a command value of the electric output which is transmitted from the power converter. The power converter controller controls the output of the power converter in response to an active power command value, depending on a reduction amount of a system voltage when instantaneous reduction occurs in the system voltage interconnected with the wind power generating equipment. This permits stable operation of the wind power generating system when instantaneous voltage reduction occurs such as during a system abnormality.
