Base on the units starting-up and commissioning process in a power plant, this paper introduced the structure characteristics and starting-up processs control technologies of 1 000 MW steam turbine with SIEMENS technology. Problems in starting-up and commissioning process were analyzed, and some proposal were put forward for the commissioning of 1 000 MW ultra-supercritical unit and the optimization of boiler steam-blowing, which could provide references for other units commissioning.
