Hydroelectric – Hydraulics for power plants and water turbines

---

Hydraulic challenges in the hydroelectric sector

A hydroelectric power plant demands precision control and continuous availability from hydraulics: the turbine governor must modulate the distributor and the blades with a fast, repeatable response, while the gate actuators and dam operating equipment must deliver force and safety even after long stand-by periods. The work involves long strokes, humid environments, environmental constraints on the fluid and the need for scheduled maintenance on plants that stay in service for decades.
