An automatic control system enabling comprehensive operation of a reheat steam turbine with sliding or constant pressure boilers. The control system includes an HP control valve for regulating steam flow to the high pressure turbine according to load and speed demands, an intercept valve for regulating steam flow to the low-pressure turbine and for reheater pressure control, and a bypass flow system for bypassing excess boiler steam during periods of low loading. The bypass system includes a high-pressure bypass sub-system and a low-pressure bypass sub-system, each having a flow control valve and provision for desuperheating the steam.
