However, the water in the turbine flows parallel to the shaft. This turbine can provide high efficiency of about 94% under no load condition and up to 15-20% in the

KAPLAN HYDRO TURBINE EXCELLENT PERFORMANCE IN A RANGE OF APPLICATIONS With a double regulation system, Kaplan turbines provide high efficiency over a broad range of configurations The vertical configuration of the Kaplan turbine allows for larger runner diameters (above 10 m) and increased unit power, as compared to Bulb Turbines. Large Kaplan turbines are individually designed for each site to operate at the highest possible efficiency, typically over 90%. They are very expensive to design, manufacture and install but operate for decades.

Efficiency loss for Kaplan turbine due to load frequency regulation Kaplanturbinen har i förhållande till Francis och Peltonturbinen fler

Kaplan turbine performance represented in the form of the relationship between the incoming water flow and the pitch angle.

Flow 4 - 55 m 3 /s.

Kaplan turbine works at high flow rate of water and low head with maximum efficiency that is not possible in Francis turbine. It is is also called a propeller turbine. Classic solution for the exploitation of high water volumes and low heads, Kaplan Turbines benefit of high efficiency even with wide flow rate range, thanks to the Kaplan turbine, propeller turbine etc.,.

Based on one selected Kaplan turbine, Selsfors G1, measurements and on the other hand lower turbine efficiency and worse quality of the frequency control.

If the water flows parallel to the axis of the rotation of the shaft the turbine is known as axial flow turbine. And of the head at the inlet of the turbine is the sum of pressure energy and kinetic energy and during the flow of water through runner at part of pressure energy is converted into This type of turbine is particularly suitable for high head applications with variable flow, its efficiency is not very sensitive to the variation. Small Pelton turbines can achieve mechanical efficiency (to the shaft) of 90%. Turbine Francis (1868) Drop height: 10 - 700 mètres Knowing that a Kaplan turbine can produce up to 200 MW, we can evaluate the financial loss for an average 50 MW turbine with 92% efficiency at maximum output.

This can be capable of working at low head and high flow rates efficiently which is hard for Francis turbine. Kaplan turbine works more efficiently with the head

It is smaller in size and easy to construct. The efficiency of Kaplan turbine is very high as compares with other hydraulic turbine. Disadvantage of Position Kaplan turbine Installation of the system is still not there, then the channel discharge channel contained in steam power plants have to be modified in order Kaplan turbine placement can be done well. 3.1 Block Diagram of hydro power Fig. 5.
