The Kaplan turbine is a type of water turbine used for hydroelectric power generation. It is designed to operate efficiently at low water heads and high flow rates. The turbine features adjustable blades, allowing it to adapt to varying water conditions, which enhances its efficiency and performance. Invented by Viktor Kaplan in the early 20th century, the Kaplan turbine is a propeller-type turbine. It consists of a runner with blades that can be tilted to optimize energy extraction from flowing water. This design makes it particularly suitable for river and dam applications, contributing significantly to renewable energy production.
