PROBLEM TO BE SOLVED: To provide a wind power generation system capable of suppressing an overspeed-caused heavy load from acting on blades when a wind turbine is stopped.SOLUTION: Wind turbine stop factors are classified according to circumstances. If one stop factor is at least a revolving-speed upper limit abnormality (overspeed), a wind turbine control panel transmits a command to continue generating power to a power controller and transmits a command to transition a blade pitch angle into a stopped state to a pitch controller. The wind turbine control panel transmits the command to transition the blade pitch angle into the stopped state to the pitch controller first, and transmits a power generation stop command to the power controller after passage of predetermined time or if a predetermined condition is satisfied.SELECTED DRAWING: Figure 2 |
