A rising temperature of components of an electric generator is restrained without deteriorating the quality of electricity output and the user-friendliness of the electric generator. AVR (7) and a temperature detecting means (75) is provided in a generator housing. While the detected temperature is greater than the limitation starting temperature, the output voltage is decreased by decreasing the control target value (for the AVR (7)) in accordance with the temperature. A range between the power generation stopping temperature as an upper-limit temperature of a generator component and the limitation starting temperature set to be a lower than the power generation stopping temperature is defined as a voltage droop range. In the voltage droop range, the control target value is decreased in accordance with a target voltage base value preset in a relationship with the temperature so that the decrease degree becomes greater in proportion to a rising temperature.
Description
technical field [0001] The present invention relates to an output control device of a generator, and more particularly, to an output control device of a generator having a function of suppressing temperature rise of components of the generator. Background technique [0002] Each structural part of the generator has an upper limit temperature that can be used. Therefore, such countermeasures are taken: improving the configuration of the structural parts, or forcing the atmosphere around the structural parts to make the structural parts cool when the generator is running. The upper limit temperature will not be exceeded. As for the arrangement structure, for example, structural components are arranged in positions where they are easily exposed to the outside air as much as possible so that they can be easily cooled, thereby suppressing the temperature rise caused by the temperature of the working atmosphere or the structural components themselves due to heat generation. In th...
