Objectives:
- To learn about type of turbine used in hydroelectric generator.
- To gain knowledge about turbine efficiency.
- To analyse the turbine behaviour and determine the suitable turbine for proposed systems.
Content / Procedure:
- Get the information from book, video and document.
- Compare the types of turbine.
- Justify the right turbine for proposed systems.
- Try to produce my own customized turbine based on specification given.
Result and Analysis:
- The turbine used to converts the energy in the water into electricity.
- Many types of turbines available, so it is important to match the turbine to the system's condition of water head and flow.
- The Pelton wheel have been chosen as a suitable turbine in proposed systems due a few factors such as performances, reliability and cost.
- All the turbine types, the energy of falling water is converted into rotary motion in the runner's shaft.
- This shaft is coupled directly or belted to either a permanent magnet alternator, or a synchronous or induction AC generator.
- The compilation of picture below, shows the characteristic and the load of work that has been done during this part.

- The turbine was been made by my own because it is difficult to be find in Malaysia.
- The turbine made from motor gear, 9 metal spoon, bearing and the shaft.
- The wheel which is suitable for nozzles up to 13 mm diameter with nozzle aligned such that jet strikes runner in centre of bucket.
Conclusions
- I'm choose a Pelton Wheel turbine to be used at hydroelectric generator.
- Pelton wheel turbine is a most suitable choice based on few criteria.
- The efficiency of turbine surely will be reduce cause of the own made turbine, but the performance is not far compare to the real one.
