Abstract

Hydraulic turbines with variable pitch blades are usually controlled by a cam which is actuated so that the required relationship between blade and angle and gate opening is maintained. The profile of the cam is determined by trial and is consequently a lengthy and expensive procedure. An alternative control system for the blade angle operates electronically. A computer memory stores information which defines the blade angle corresponding to any given gate opening. A signal generated by the blade is compared with a signal from the computer. A signal is then transmitted to the electric circuit controlling the blade angle to adjust the angle to correspond to the value stored in the computer.
