Title:
WIND POWER GENERATION FACILITY, METHOD FOR OPERATING SAME, AND WIND FARM CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/112033
Kind Code:
A1
Abstract:
A wind power generation facility equipped with: a wind farm that includes multiple wind power generation devices each having a synchronous generator; a local grid to which the wind farm is connected; a direct current power transmission route provided between the local grid and a grid; a sending end converter for converting the alternating current power from the local grid into direct current power, and supplying the direct current power to the direct current power transmission route; a receiving end converter for converting the direct current power from the direct current power transmission route into alternating current power, and supplying the alternating current power to the grid; a fault detection unit that detects abnormal events in the grid; and a first wind farm controller that, when an abnormal event in the grid is detected by the fault detection unit, controls the sending end converter and adjusts the local grid voltage phase so as to reduce the load angle, which indicates the difference in the generator voltage phase of the synchronous generators of the wind power generation devices with respect to the local grid voltage phase in the local grid.
