WIND POWER GENERATION FACILITY, METHOD FOR OPERATING SAME, AND WIND FARM CONTROL DEVICE

摘要

A wind power generation facility (1) includes: a wind farm (10) including a plurality of wind turbine generators (12) each of which includes a synchronous generator (15); a local grid (2) to which the wind farm (10) is connected; a direct-current transmission channel (26) disposed between the local grid (2) and a grid (4); a sending end converter (22) for converting alternate current from the local grid (2) into direct current and supplying the direct current to the direct-current transmission channel (26); a receiving end converter (24) for converting the direct current from the direct-current transmission channel (26) into alternate current and supplying the alternate current to the grid (4); an abnormality detection part for detecting an abnormal event of the grid (4); and a first WF controller (30) for controlling the sending end converter (22) and adjusting a local-grid voltage phase (D SEC ) of the local grid (2) so as to reduce a load angle which indicates a difference between a generator voltage phase of the synchronous generator (15) of each wind turbine generator (12) and the local-grid voltage phase (D SEC ), when the abnormal event of the grid (4) is detected by the abnormality detection part.
