Abstract

PURPOSE:To restrain the output of a generator from fluctuating by compensating the fuel flow rate for the heating value in only the fluctuated amount after switching over the fuel control gain in case the heating value of the gas fuel fluctuated in a plant where two different kinds of gas fuel are used. CONSTITUTION:The air compressed by a compressor 1 is heated in a combustor 2 to make it a high temperature gas. The high temperature gas does a job to drive a generator 4 in a turbine 3. As the result, electricity generated is transmitted to a system 6 through a circuit breaker 5. On the other hand, a velocity ratio valve 22 and a gas fuel control valve 23 are controlled by a fuel control device 8, respectively, causing the fuel flow rate flowing into the combustor 2 to be controlled. This constitution detects that the fuel of different heating valve is being supplied on the basis of the output difference of the generator 4 against the fuel control signal. When this is detected as mentioned above, the gain of the back pressure of the velocity ratio valve 22 is switched over.
