Start-Up and Commissioning of GE 660MW Steam Turbine

According to the actual circumstances during the c ommissioning of the turbines in the 3rd phase project of Huaneng Dezhou Power Pl ant, the commissioning and startup process and characteristics of the 660MW turb ines manufactured by GE are briefly described. The problems phenomena and its so lution to the troubles are introduced, the performance of the startup control sy stem is also analyzed in this paper. The essential preparation and investigation work before the commissioning and startup of similar turbines are put forward, which will be beneficial to the smooth commissioning and startup of imported lar ge-capacity turbines.
