Abstract: The deviation occurred in locating of intermediate pressure differential expansion detector of S109FA single shaft gas-steam combined cycle unit in the Wangting Power Plant was introduced. The reasons of deviation occurred in locating of intermediate pressure differential expansion detector were analyzed. The solution was put forward; the locating method to eliminate the deviation was discussed. 

Key words: intermediate pressure differential expansion, thrust bearing pad, axial displacement, dead point, gap, deviation
