Abstract
System and method for controlling operation of a hydroelectric production system comprising electrical actuators operably connected at opposite positions of a gate operating ring for rotating the wicket gates to a desired position. The system receives a single control signal designed for a hydraulic system comprising hydraulic actuators operably connected to a single fluid reservoir and configured to work in tandem to produce simultaneous and opposite axial movements. The system comprises a control interface adapted to produce new control signals, each new signal being intended to a different electrical actuator to cause the electrical actuators to have axial movements which are identical in speed and in opposite directions to substantially imitate the exact movement of the hydraulic actuators onto the gate operating ring. The system is configured to introduce a dampening effect to reduce sudden acceleration and deceleration which is purposely used in hydraulic systems to overcome friction and static effects.
