In a turbine system with first and second turbine stages, each having a bypass line thereacross, provision is made for utilizing only the valving of the first turbine stages to control the acceleration of the shaft driven by the turbine system from start-up to synchronous speed. At the same time, provision is made for diverting enough of the flow to the second turbine stages to meet the requirements of those stages.
