Electric power plant and turbine acceleration control system for use therein
An electric power plant having dual turbine-generators and a steam source which includes a high temperature gas-cooled nuclear reactor. Each turbine includes a high pressure portion driven by superheat steam and a lower pressure portion driven by reheat steam. A turbine bypass system permits minimum flows of superheat and reheat steam from the source at times when the turbines require flows of such steam that are less than the minimum flows. Before it is reheated, steam that has passed through the high pressure portions and their bypass lines drives auxiliary steam turbines that rotate means for propelling the coolant gas through the reactor. During acceleration of a turbine-generator to its synchronous speed, one of the steam flows through its high and lower pressure portions is varied to govern the shaft speed, while the other flow is held relatively constant, that one of the flows which is varied being determined by the shaft speed. As the turbine-generator is accelerated, the steam flow through a bypass line associated with its lower pressure portion is varied to compensate changes of flow through that portion, in order to maintain a desired pressure of hot reheat steam.
