<p>PROBLEM TO BE SOLVED: To provide a wind turbine generator system which reduces a load of a blocker arranged in a DC transmission passage for transmitting DC power to a grid from a wind turbine generator, and can improve a life of the blocker.SOLUTION: The wind turbine generator system comprises: at least one wind turbine generator; the DC transmission passage for supplying power to the grid from at least one wind turbine generator; an AC-DC converter for converting AC power from at least one wind turbine generator to DC power and supplying it to the DC transmission passage; a DC-AC converter for converting the DC power from the DC transmission passage to AC power and supplying it to the grid; a DC blocker arranged at the DC transmission passage; a turbine control part for making at least one wind turbine generator reduce a power generation output when an abnormality of the DC transmission passage occurs; and a blocker control part for opening the DC blocker when a current of the DC transmission passage becomes not higher than a threshold when the abnormality of the DC transmission passage occurs.</p> |
