Stay Vane
A Stay Vane is an essential part of hydroelectric power plants that helps control and guide water flow into turbines. Think of it as a specialized guide rail system that ensures water moves smoothly and efficiently through the power plant. These structures are crucial because they help prevent water swirl (like a whirlpool in your bathtub) that could damage equipment and reduce power generation efficiency. They're sometimes called 'guide vanes' or 'stationary vanes' because they don't move, unlike other parts of the system that do rotate.
