    Patent number: 4791309
    Abstract: A hydroelectric power system has a reservoir (prime mover) (17) driving an electrical generator (10) which supplies a consumer load (B) and an auxiliary load (14). A control system (11) operates control (15) for the prime mover, control (13) for the auxiliary load and/or control (12) for the consumer load in response to a signal from the generator (10) or some other source, so that the supply is stabilized so far as possible to a minimum. Normally no energy is dissipated in the auxiliary load, except during a control sequence.
