<p>PURPOSE:To effectively operate a turbo generator and a shaft generator by detecting variation in an input vapor amount by a pressure signal oscillator, comparing the pressure signal with a set pressure to obtain a deviation, automatically altering the set value of a governor in response to the deviation, and subsequently automatically altering the opening of a vapor amount control valve. CONSTITUTION:When an output of a main engine 1 is raised, vapor amount is increased, a pressure detection signal is compared with a set pressure to automatically obtain a deviation signal. This deviation signal automatically raises the set value of a governor 18 to increase the opening of a vapor amount control valve 16, and the output and frequency of a turbo generator 19 are raised as compared with reference values. The frequency is automatically detected to so control it as to reduce the output of a shaft generator 21. Then, the sharing power of the generator 19 is increased, and the sharing power of the generator 21 is decreased. Here, in the case of the deviation in which the vapor pressure is higher than the set pressure, marginal power is supplied to the generator 21 if the generator 19 has room for load.</p> |
