<P>PROBLEM TO BE SOLVED: To provide a power generation device inhibiting the generation of cavitation in a pump circulating a working medium while avoiding complication of the construction. <P>SOLUTION: The power generation device includes: a pressure sensor 11 provided in a flow passage between a condenser 3 and the pump 4 in a circulation flow passage 6 and detecting pressure of the working medium on an inlet side of the pump 4; a temperature sensor 12 provided in the flow passage between the condenser 3 and the pump 4 in the circulation flow passage 6 and detecting temperature of the working medium on the inlet side of the pump 4; a derivation means 21 deriving the saturated steam pressure of the working medium on the inlet side of the pump 4 from the detected value of the temperature sensor 12; and a regulation and control means 23 regulating a circulation amount of the working medium according to a differential pressure between the saturated steam pressure derived by the derivation means 21 and the pressure of the working medium detected by the pressure sensor 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
