OUTPUT CONTROL DEVICE OF COMBINED CYCLE POWER GENERATING SYSTEM

Japanese Patent JPS5912106

A

PURPOSE:To make the setting of various running modes possible by a method wherein plural shafts of single shaft type combined cycles are provided and arbitrary number of the shafts thereof are subjected to load with the same percentage as a unit or subjected to load with different percentage from one shaft to another respectively. CONSTITUTION:The output control device is provided toward the respective speed setters 29, 33 and 37 of (n) shafts of single shaft type combined cycles. In said device, the output, which has past through a selector 21 to select either the output instruction from a central load-dispatching office 17 or the setting signal from a load setter 20, is added with the output of a function generator 22A based upon frequency deviation DELTAf. After that, the output sum of total shaft generators, sent from a load detector 23 is subtracted 24 from said added value. The resultant subtracted value is proportionally integrated 25 in order to obtain the output instruction common to each shaft. Then, the output instruction is sent to the subtractors 27, 31 and 35 of the respective shaft control systems in order to subtract the outputs of the load detectors 26, 30 and 34 of the respective shafts therefrom and to proportionally integrate 28 the resultant subtracted values to obtain the outputs given to respective speed setters 29, 33 and 37.
