SHAFT DEVIATION MEASURING DEVICE, SHAFT DEVIATION MEASURING METHOD, SINGLE-SHAFT COMBINED PLANT USING THIS SHAFT DEVIATION MEASURING DEVICE, AND METHOD OF ACTIVATING THIS SINGLE/SHAFT COMBINED PLANT

摘要

PROBLEM TO BE SOLVED: To provide a shaft deviation measuring device which measures shaft deviation between two shafts at the clutch fitting time, and a single-shaft combined plant comprising this shaft deviation measuring device.;SOLUTION: In a controlling device 10, an amount of shaft deviation between a shaft 3a of a gas turbine 3 and a shaft 5a of a steam turbine 5 is measured, and the speed rising rate of the rotational speed of the steam turbine 5 and the heat soak time are set according to the shaft deviation amount measured, so that the shaft deviation amount when a clutch 7 couples the shafts 3a and 5a is defined within an allowable range.;COPYRIGHT: (C)2005,JPO&NCIPI
