Digital simulation of an impulse turbine: the Bradley Lake Project

A digital simulation and stability study of the Bradley Lake (Alaska) hydroelectric project is discussed. The basic system consists of two 45-MW, multiple-jet impulse turbines supplied by a three-mile conduit. A digital governor is utilized. Once produced, the simulation is used to investigate the stability of the system. The system was found to be locally stable, but unstable to large perturbations. Due to economic constraints in plant design, the response of the system to load acceptance is poor.<
