Abstract
It is an object to enable stable operation of a wind turbine and to change a control parameter of the wind turbine at an appropriate timing. A dynamic-characteristics model of a wind turbine is identified for each of a plurality of ranges that are determined in accordance with wind speed, and the identified dynamic-characteristics model is monitored for each of the ranges.
Claims5
