Dynamic Response of a Hydroelectric Plant

Frequency-response tests have been made on the turbines at the Apalachia Hydroelectric Plant, of the Tennessee Valley Authority, to check the validity of previously derived mathematical expressions. These tests confirmed in general that the mathematical expressions could be used to describe the performance under all major operating conditions and for the direct design of nonlinear power system controls. Hydraulically, this is the most complicated installation east of the Rockies.
