WIND TURBINE GENERATOR SYSTEM AND WIND TURBINE GENERATOR

摘要

An object of the present invention is to make use of wind energy as effectively as possible and increase the amount of generated energy that is supplied to a power system. A power storage apparatus (30) is interposed between and electrically connected to a wind turbine generator (10) and a power system (40). The wind turbine generator (10) outputs, to the power system side, an amount of active power obtained by subtracting auxiliary machine loss, which is power consumed by an auxiliary machine, from the maximum active power that can be output by a generator (18), and if the amount of active power output from the wind turbine generator (10) exceeds a limited power value set for the power transmission end, a charge/discharge controller (31) that controls the power storage apparatus (30) causes the power storage apparatus (30) to be charged with part of the power output from the wind turbine generator (10).
