WIND TURBINE GENERATOR SYSTEM, WIND TURBINE GENERATOR CONTROL DEVICE, AND WIND TURBINE GENERATOR CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To reduce generated electrical power reduction by reducing the number of wind turbine generators to be stopped.

SOLUTION: This wind turbine generator system includes: a transmission/reception section 51 receiving operation information including information on wind speed received by each wind turbine generator in a wind farm through a network 5; a wind speed threshold determination means 52 determining whether or not wind speed is higher than a predetermined threshold; a correlation coefficient calculation means 53 calculating the correlation coefficient of the wind speed between the wind turbine generators; a stop determination means 54 selecting such a wind turbine generator that it is determined by the wind speed threshold determination means that the wind speed is higher than the threshold and it is determined that an operation result calculated by the correlation coefficient calculation means is higher than a predetermined value; and a stop command means 55 transmitting a stop command to the wind turbine generator selected by the stop determination means.
