Abstract

PURPOSE: To quench undue running of a turbine by using control signals in comparison of the minimal load requiring signal corresponding to various fuels with the load setpoint.
CONSTITUTION: Load setpoint P0 and minimal load requiring value from boiler controllers ABC are input to a high value selecting circuit 40, and its output is applied as a settled load value to an adding part 35. In case where the load setpoint P0 and the minimal load requiring value are compared by a comparator 41, and the load setpoint P0 is smaller than the minimal load request, during the existence of turbine velocity within the predetermined range which is larger than the rated velocity of the turbine, the turbine is prevented from undue running by controlling the arranged ratio.
