Abstract

PURPOSE: To improve the efficiency by exhaust air temperature by making the efficiency itself a control object on controlling the inlet guide vane provided at the compressor of gas turbine.
CONSTITUTION: The optimum efficiency in certain requested load fed from the load request signal generator 14 of the dynamo is obtained by the function generator 15. On the other hand, the efficiency is obtained by the function generator 18 from both signals given by the dynamo power converter 16 and fuel flow converter 17. The difference between the setting value and the actual value of efficiency is computed by the proportional integrator 10 to produce an inlet guide vane position signal. The greater value of both the said signal and a signal of the lower limit position setter 19 is obtained by the greater value priority circuit 20. The deviation between the said value and the actual inlet guide vane position is proportionally integrated to control the position of guide vane.
