PURPOSE:To obtain reliability of a power system, to maintain and improve stability of a generator. CONSTITUTION:A power generator 11 comprises a generator 12 for generating in response to a field voltage Ef, a fuzzy control system 15 for fetching a terminal voltage Ea to be output from the generator 12 and an armature current I to fuzzy control them to form an exciting command DELTAEf, and an exciter 14 for forming a field voltage Ef based on the command DELTAEf. The system 15 multiplies a deviation (Ea-Eas) between the voltage Ea from the generator 12 and a terminal voltage set value Eas, a changing speed (dEa/dt) of the terminal voltage, a deviation of effective power P, a changing speed (dP/dt) of the deviation of the power P by a gain responsive to a preset function, and calculates an exciting command DELTAE to the exciter 14 based on the calculated results. |
