Generator protecting device for wind power plant
专利汇可以提供Generator protecting device for wind power plant专利检索，专利查询，专利分析的服务。并且PURPOSE:To restrict the temperature rise of the inside of generator by a method wherein the pitch angle of the blade of a wind power turbine is reduced with respect to the direction of wind by a predetermined value in accordance with the output of a temperature detector, outputting a signal when the temperature of the inside of the generator has exceeded a given value, to reduce the output of the turbine. CONSTITUTION:When wind speed has caused frequent sudden changes, the generator 3 has outputted outputs higher than a short time specified output and the temperature in the generator has risen to exceed a given value, a signal is outputted from the temperature detector 7 and is inputted into a wind power turbine control unit 2. When the signal from the temperature detector 7 has been received by the control unit 2, the unit 2 reduces the pitch angle of the blade by a predetermined angle to reduce the output of the generator 3 and controls the temperature in the generator so as to be lower than an allowable temperature. When the temperature in the generator has been decreased to a value lower than a given value, the output signal of the temperature detector 7 is eliminated, the pitch angle of the blade is returned to the initial angle thereof and the generator 3 outputs the rated output thereof. According to this method, even if the wind power, enough to generate a power higher than the rated output of the generator, is generated, the temperature in the generator may be restricted and the operation of the plant may be continued.，下面是Generator protecting device for wind power plant专利的具体信息内容。
