Title:
WIND POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/140635
Kind Code:
A1
Abstract:
[Problem] To provide a wind power generation system equipped with a wind power generation mechanism and a charging/discharging device, smoothing output to a system by the transmission of the output of wind power generation to the charging/discharging device and by the output from the charging/discharging device to the system, and capable of stably smoothing the output to the system without incurring increase in the capacity of the charging/discharging device. [Solution] The wind power generation system is equipped with a wind power generation mechanism and a charging/discharging device and smoothes output to a system by the transmission of the output of wind power generation to the charging/discharging device and by the output from the charging/discharging device to the system. The wind power generation system is also equipped with a pumped hydropower mechanism and selectively performs at relatively short predetermined time pitch of several ten seconds to several minutes: water pumping using the pumped hydropower mechanism powered from the charging/discharging device; water power generation using the pumped hydropower mechanism using the drop of pumped water; and transmission of the output of the water power generation to the charging/discharging device. The selection is performed based on: a wind power generation output average value in the immediate previous pitch; and the amount of stored electricity of the charging/discharging device at the immediate previous pitch end point of time.
