Abstract: Present speed control governors for hydroelectric installations employ constant gain settings. This paper develops appropriate gain functions of load level for optimal (deadbeat sense) transient ...

Abstract: In the case of Kaplan turbines the consideration of the efficiency parameter is critical from the control strategy synthesis viewpoint. As it is not essential in hydrosystem analysis, explicit ...

Abstract: A procedure is presented for the generation of the optimal gate closure schedule for the case of full load rejection on an isolated hydroelectric system. Constraints are placed on turbine ...

Abstract: This paper develops a program for closed loop simulation of the transient behavior of a hydroelectric composite. The system modeling is comprehensive, including such factors as governor nonlinearities ...

Abstract: Traditionally, speed control of hydrogenerators has been implemented by analog proportional-plus-integral control of speed error. With digital controllers, nonlinear, adaptive control strategies may ...
