An operation method for a wind farm (1) including wind turbine generators (2, 3), at least one feeder (14, 16) to which at least one of the wind turbine generators (2, 3) is connected, and a substation (30) disposed between the at least one feeder (14, 16) and a grid (50), includes: a terminal voltage detection step of detecting terminal voltage of a generator belonging to each of the wind turbine generators (2, 3); a provisional control step of, when fall of the terminal voltage is detected in the terminal voltage detection step, reducing mechanical input to the generator of each of the wind turbine generators (2, 3) and increasing reactive current outputted from the generator; and a fault spread suppression step of, when it turns out after starting the provisional control step that the fall of the terminal voltage occurs in association with a fault on a feeder side of the wind farm (1) with respect to the substation (30), reducing the reactive current which is increased in the provisional control step so as to suppress spread of the fault inside the wind farm (1). |
