WEEK 10: PULLEY SYSTEM

Objectives: 
  • To find a problem of hydroelectric prototype.
  • To analyse the prototype performance.
  • To solve a problem occur within time limit.
Content / Procedure: 
  • Make a component test towards such as alternator, battery and rotation of the turbine.
  • Ensure the right configuration has been done.
  • Do a component test. Check the rotation of the turbine and the alternator shaft using tachometer.
  • To identify the problem by doing a research, ask a supervisor and get a consult from wireman.
Result and Analysis:
  • I'm done a test about alternator part and found another problem that need to be solve quickly. This is involved about alternator also.
  • The rotation of the turbine shaft was not fast enough to achieve a standard speed of alternator in order to produce a voltage.
  • The car alternator needed at least 1600 rotation per minute to produce an approximately 12 V voltage. The battery must always connected to give an excitation voltage towards alternator.

WEEK 9: ALTERNATOR TROUBLESHOOT


Objectives: 
  • To find a problem of hydroelectric prototype.
  • To analyse the prototype performance.
  • To solve a problem occur within time limit.
Content / Procedure: 
  • Make a component test such as towards, alternator, battery and rotation of turbine.
  • Ensure the right configuration has been done.
  • Do a component test. Spray the water towards the turbine and find the voltage reading in Multimeter..
  • Try to identify the problems by doing a research, ask a supervisor and get a consult from wireman.
Result and Analysis:
  • The test has been done at the toilet and i find the alternator can not produce a voltage. The reading was get only from the battery.
  • When the current measurement done before the rotation of turbine and after the turbine rotated, the current and voltage value get are same which is 12 V, produced only by battery.
  • The pictures during alternator troubleshooting has been shown below.

WEEK 8: MECHANICAL CONSTRUCTION


Objectives: 
  • To make an configuration of the hydro material.
  • To build a proper hydroelectric prototype.
  • To check an suitable approach that can meet the goal of the project.
Content / Procedure: 
  • Make a configuration based on specification on each material.
  • Understand the function of each mechanical items.
  • Justify the cost and what component to be used.
  • Troubleshoot the prototype in order to determine problem.
Result and Analysis:
  • This project did not have a software programming because of the higher cost, and based on the objective project itself. 
  • In other means, the mechanical material is one of the parts that need to be focusing on during this project.
  • The mechanical material must be done properly. It is because, hydroelectric systems is depend on the accurate place, timing and proper design in order to produce a right output.

WEEK 7: BUY MECHANICAL MATERIAL


Objectives: 
  • To find a suitable mechanical parts.
  • To compare the specification of the material.
  • To justify the right material that meet the right cost.
Content / Procedure: 
  • Make a research about items that need to be used.
  • Go to Jalan Pasar and Kepong to find the the material.
  • Do a component test.
  • Make an analyse about hydroelectric operation systems.
Result and Analysis:
  • I'm done a few research about operation and simpler systems of hydroelectric in market. Most of it is using the bigger turbine in order to produce a higher electricity.
  • So, the comparison between common hydro systems that usually use in village or small hydro has been used as reference.

WEEK 6: TURBINE VERIFICATION


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.
