PROBLEM TO BE SOLVED: To provide a Rankine cycle control method capable of recovering waste heat with temperature fluctuation more efficiently than a conventional method.SOLUTION: A Rankine cycle control method controls a generator 10 in a manner that brings a rotation speed of a turbine shaft 9 in line with a required rotation speed Rn by: adjusting a rotation speed of a pump 4 so that a measurement value Ti of an inlet temperature sensor 13 installed at an inlet of a turbine 7 has a predetermined degree of superheat S; deciding steam pressure Pe of working fluid 3 at a temperature obtained by subtracting the degree of superheat S from the measurement value Tw of a waste heat temperature sensor 14; and deciding the required rotation speed Rn of a turbine 7 on the basis of the measurement value Rp of a pump rotation sensor 16, the steam pressure Pe and a predetermined map data.SELECTED DRAWING: Figure 1 |
