Abstract

PURPOSE: To synchronize the revolution number of primary turbine with that of secondary turbine by changing the inflow of the vapor stream of primary turbine, controlled by opening or closing control valve, through a reheater.
CONSTITUTION: The revolution number commander 13 consists of the comparator 14 to determine the timing of the control of speed matching valve, the level detector 15 to obtain the deviation Δn between the revolution numbers of primary and secondary tubines, the accelerating rate setter 16 to set up the accelerating rate command value of secondary turbine according to the deviation Δn, and the revolution number calculator 17. Speed matching control is made up to a accelerating rate set value which is set up in advance as accelerating rate command value for secondary turbine, and at the end of the speed matching control period T1, the accelerating rate command value of the secondary turbine designates the accelerating rat command value of the primary turbine and an accelerating rate matching control is made.
