METHOD AND DEVICE FOR WIND POWER GENERATION OUTPUT STABILIZATION

摘要

PROBLEM TO BE SOLVED: To stabilize a power supplied to a power line by a wind power generator. SOLUTION: A wind power generation output stabilization device has a power detector 8 which detects a power to be supplied to a power line 7 from a wind power generator 3, a converter 10 by which a power generated by the wind power generator 3 can be supplied to a battery 9, an inverter 11 by which a power stored in the battery 9 can be supplied to the power line 7, a calculator 12 by which the average value of the power generated by the wind power generator in a very short unit time period is obtained in accordance with a signal 8s from the power detector 8 and a controller 13 which makes line converter 10 or the inverter 11 selectively operate in accordance with a signal 12s from the calculator 12 and the signal 8s from the power detector 8. The excessive part of the power generated by the wind power generator 3 is stored in the battery 9, and the shortage part of the power generated by the wind power generator 3 is supplied to the power line 7 from the battery 9.
