Abstract: Provided is a control apparatus of an extracted air booster system of an integrated gasification combined cycle power plant, which control apparatus can additionally serve a sufficient pressure control function and a sufficient antisurge control function. For example, when an inlet guide vane is fully closed or has a small opening degree equal to or smaller than a predetermined opening degree, a second control section of the control apparatus of an extracted air booster system performs pressure control based on a pressure deviation, instead of or as well as antisurge control. In the pressure control, the degree of opening of an antisurge valve is controlled so that a booster outlet pressure detection value can become equal to a set pressure value. In a case where a pressure ratio is larger than a set pressure ratio value, it is also effective that the second control section performs the antisurge control even when the inlet guide vane is fully closed.

The outer loop can pulses the loop on a longer time scale, resulting in two pulse periods. Through timing, a reformate peak from one period is made to overlap a temperature peak from a previous period.
