1. A 40 MW water turbine is coupled to a 50 MVA 3-phase AC generator rated for 0.8 lagging power factor operation. The losses of the generator are negligible. It is required to deliver a load of 30 MW at 0.5 pf leading by the set. (A): The set cannot deliver the load. (R): The turbine will be overloaded. (A): The synchronous condenser does not require so large shaft and bearings as the synchronous motor (R): The synchronous condenser does not supply any load torque. (A): The steam turbines run at high speeds (R): The efficiency of a steam turbine increases with increase in speed.
