Abstract

PURPOSE: To accurately obtain the output of a turbine that cannot be observed, by gaining an output signal of the turbine from a turbine speed signal and a load signal, and by controlling the turbine so that the output signal of the turbine be indentical to an output demand signal of the turbine.
CONSTITUTION: A turbine speed signal N obtained by a speed detector 11 is input to a differentiator 41 and a function generator 43, and a turbine speed signal gained by the differentiator 41 is sent to a coefficient instrument 42 setting turbine starting time constant T, thus obtaining a turbine acceleration energy signal. Meanwhile, the turbine speed signal N is input to the function generator 43, thus gaining a loss signal in case of no-load. A load signal L obtained by a load detector 14 is input to a function generator 44, thus gaining a load loss signal.
