PURPOSE:To enable quick response by increasing and decreasing load sharing command for each main engine of a general load controlling system in which plural main engines having exclusive controlling system share load based on preset load variation rate. CONSTITUTION:Main engine of each shaft consists of a gas turbine 1, a waste heat recovering type boiler 2 that generates steam by the waste gas, a steam turbine 3 driven by generated steam and a generator 4, and forms No.1 shaft 5. There are No.2-No.6 shafts 6-10 of similar main engine constitution, and a large capacity plant is constituted as a whole. Shaft controlling devices 12-17 that make control of each shaft are provided for each shaft. Further, a general load controlling device 19 that gives shaft load command to each shaft according to system load demand as a whole plant consisting of load request from a central feed instruction station. By controlling 19 share of load of each main engine basing on preset load variation rate, quick response for variation of load is made possible. |
