Governor Tests by Simulated Isolation of Hydraulic Turbine Units

Abstract
Test and adjustment of hydraulic turbine governors has been an unfortunately complicated process involving the optimization of several interrelated variables. In earlier years stable performance was achieved by empirical adjustments in the field on isolated load, but optimum was seldom achieved. In more recent years the interconnection of systems has denied the opportunity for testing of units on isolated load. Nevertheless, the interconnection of systems actually places a higher premium on good coordination. Optimization by test and adjustment of individual parameters has yielded improvement but it is limited in dealing with nonlinearities.
