Hydraulic-power units in Colorado’s Carter Lake are being fit with smart systems to optimize the flow rate of water through the dam. Through the use of PID controllers, position feedback devices, and backup manual valves installed in parallel Carter Lake Hydroelectric maintains the flow of water through its wicket gates in turn regulating the generation of electricity from the flowing water.
The entire hydaulic system is designed for long term use with little maintenance. Redundant oil filters maintain internal hydraulic components, fluid check valves prevent counter-flow from harming sensitive pressure sensors and flow meters.
