CONTROL DEVICE OF WIND FARM, WIND FARM, AND CONTROL METHOD OF WIND FARM |
摘要 |
<p>To prevent disconnection of wind turbine generators due to changes in wind conditions even if the wind turbine generators is operated to limit the power output. A plurality of wind turbine generators (14) that generate electric power by the rotation of rotors are provided in a wind farm (10) are interconnected and are operated while the power outputs are limited in advance so as to be able to further supply electric power to a utility grid (20) in response to a decrease in the frequency or voltage of the utility grid. The rotational speed of the rotor (12), which is a physical quantity related to increase and decrease in the power output of the wind turbine generator (14), is measured for each of the wind turbine generators (14) by a wind-turbine control system (22), and the limitation amount of the power output of the wind turbine generator (14) is set for each of the wind turbine generators (14) by a central control system (16) on the basis of the rotational speed of the rotor (12) measured.</p> |
