Methods of governing:- Generally for utility steam turbines following two methods are popularly used] Nozzle governing-2] Throttle governing- Functions of governing system] To modulate the control valves to adjust the steam flow as per the load, keeping speed constant. The electrical measuring and processing of signal offer the advantage such as flexibility, dynamic stability and simple relationship of complicated functional relationship.

What is Droop? It is done because during speed controller mode a small frequency change will cause corresponding opening in valve opening hence in load. The set point is called nR. To incorporate the above facilities an integration closed loop is used. C Generator circuit breaker in open condition. A deviation of rpm will correspond to full opening of the control valve with the assumption that full opening of control valve will give full load at rated parameters. To avoid this error between set point and actual value a pressure dependent correction signal is given, as the valve opening required for running the machine at rated speed is directly dependent on steam pressure.
