Abstract

A system for controlling a hydroelectric power production facility includes sensors for detecting the presence of fish adjacent to the facility. A controller linked to the sensors controls the orientation of control surfaces associated with a turbine/generator set to enhance the survivability of fish entrained into the facility when fish are detected to be present. The system may be adapted to control fish bypass and spillway structures within the facility to further enhance the survivability of fish populations. The system balances fish survivability with other parameters related to the operation of the facility, optimizing power production levels once estimates of fish survivability meet targets or optimum levels. The system may be adapted to coordinate control of several facilities along a water system to permit implementation of an overall water, fish and power management plan.
