Abstract
PURPOSE: To suppress a progress of wear in life of the rotor when in a rapid change of the load, by operating at first a rapid load change of the gas turbine, at a time, and after the change of the steam temperature reaches a prescribed value, changing the load one by one by bypassing the output steam.
CONSTITUTION: At time t1, with a steam temperature change after ST the first stage reaching ΔTal, a change-over is made from that point to the sequential control system, to close the outlet valve of #4 boiler, and a load of #4GT is lowered from time t2, and after lowering this load to 0, the #4GT is stopped. When further ?a lowering of the load is required, the outlet valve of boiler #3 is closed successively at time t3, and after lowering the load of #3GT to 0 from time t4, #3GT is stopped. At time t5, when a load-up command comes, the load of #1, #2GT, which is now in operation is raised immediately to the rated load, and loads of the #3 and #4GT are raised successively from time t7, and the outlet valve of respective boiler is opened.
