A wicket gate is an important part of hydroelectric power plants that controls how much water flows into the turbines that generate electricity. Think of it like a adjustable door or valve system that can be opened or closed to regulate water flow. This control is crucial because it helps manage how much power the plant produces and keeps the equipment safe. People who work with wicket gates need to understand how they operate, maintain them, and troubleshoot any issues that come up. This equipment is sometimes also called "guide vanes" or "inlet gates" in job descriptions.
