Semester 2 Week 11

TITLE :

What is alternator

OBJECTIVE:

To understand the alternator

CONTENT:


An alternator is an electromechanical device that converts mechanical energy to electrical energy in the form of alternating current.
Most alternators use a rotating magnetic field with a stationary armature but occasionally, a rotating armature is used with a stationary magnetic field; or a linear alternator is used.
In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators






here is the link for the connection of the alternator

http://web.media.mit.edu/~nathan/nepal/ghatta/alternator.html


CONCLUSION;

basically there is 3 parts  of the alternator. first is the rotor as moving part,second is stator as non moving part and third is diodes.the altenator is the combining of the generator and rectifier.

Semester 2 Week10

TITLE:

Building the custom made generator


OBJECTIVE:

To investigate the output generator
To construct the generator
To test the generator


CONTENT:

Previously, im failed to build the generator which give no output voltage. i seek for my supervisor helps and ask him about the problem im faced. He told me to to this in order to make the generator. First i have to cut the plywood into a circle and as well as pro-spec to place the magnet and coil later. second i turn the coils 200 turns each with 3 anti clock wise turn and another 3 clock wise turn. third, i placed the coil 60 degree from each other with clock wise and anti clock wise intervals and connecting in series. fourth, place the magnet interval with north and south. here is the results



neo dymium magnet

Thr coil with clock wise and anti clock wise intervals




CONCLUSION:

The generator making is done and the voltage output are not high enough, it only can produce about 1.2V by rotating faster by hand. so i think it is not enough either voltage or current even i put much magnet or turn of the coils so i decide to stop wasting or finding due limited time. My supervisor advice me to use the alternator kancil to apply to my projects. I will move on what my supervisor said which just use the alternator kancil as a generator.

Semester 2 Week 9


TITLE :

Making the generator.

OBJECTIVE:

To build the 12V custom generator.

CONTENT:

this are the materials needed for making the generator.

1) magnet

2)copper wire

3)glue

4)pro-spec

5)plywood

6)cable tie



Basically, in order to make any type of the generator, the concept is the same.
here is the useful  link that help me to make my generator.

http://www.miniscience.com/kits/woodengenerator/index.html

this link, teaches how to make wooden generator and some justification on why the problem occurs when testing the generator.

i followed the steps from the above links, but had adjusted a bit because i'm not making wooden generator. The design of my generator and the materials i'm using doesn't imitate from the links due to my design the and environment place which where i placed does not suitable for wood generator (hydro generator).

1) i make 6 coils where each coil contains 200 turns

2) i attached 6 neo-dynium magnet to a circle  pro-spec using glue.

3) i attached those 6 coils onto the plywood using cable tie.


CONCLUSION;

Making the generator is done but still need to  test the generator because i need o know how either its working or not and how many the voltage being produce and minimum rp. that i need in order to produce 12V.


Semester 2 Week 8





TITLE:

The idea for making a custom 12V generator


OBJECTIVE:

To find a suitable generator for the project.

To understand how to built a generator.


CONTENT:

I need to find a generator that produced 12V  which suits the project well. after doing some research on the generator (theory parts) and with the helps from this video, i was thinking to build the generator with custom made generator which can produce 12V output voltage. the materials needed to build the custom generator are; 6 pieces of neo-dymium magnet, copper wire, pro-spec, plywood and cable tie.

CONCLUSION:

need to purchase the materials and need to start doing the custom generator ASAP.

Semester 2 Week 6 and 7


TITLE :

Angle bar


With the angle bar and the accessories that i bought, now im going to cut them join them with the jointer, bolt and nuts. It is not easy to cut them with the saw, it really sweats me a lots. i have to measure all them to make it perfectly accurate to the size or else it will not give me the right size. Besides, it will give some difficulties to joint each other.

The structure of the design


CONCLUSION:

After all the hardship to find the item and build it, now i can see almost the actual of the project. from now i can proceed to next step which are combing all the items together. But some of the items need to do through welding shop.

Semester 2 Week 4 and 5



TITLE:

Finalize the Inverter Circuits

OBJECTIVE:

To assemble the components.
Solder th components leg
To test the circuits
To placed the inverter circuit and transformer in 1 place.

DISCUSSION/ANALYSIS:

Before assembling the component. I have to check the polarity of the each components such as positive and negative of the diodes, the capacitor, the e-b-c for transistor to avoid misplaced which can damage some of the components. Place the component correctly and do double check before soldering


Soldering one by one and solder the components leg carefully to avoid damage of the circuit and the components itself. After done soldering all the components leg are not being cut for future arrangement if the mistake or misplace occurs. 

Every electronics and electric can harm people. so it must have the cover, a safe one. After successfully construct the inverter i decide to place them together and sealed as well for unreachable from people and to make my projects have a safety precaution.

I decide to make the cover from acrylic (pro-spec) because it easy to cut them and place the plug, fan and whatsoever in one place.













CONCLUSION:

The inverter circuit input and output have been tested and checked. There is no problem for the circuit. the cover for the circuit also have been build and as well as the plug and fan have been installed altogether in one box.  Proceed to next stage.

To get the information from advisor.

ANALYSIS/DISCUSSION:


In this week, it is necessary to find a supervisor or advisor to supervise the FYP (final year project). finding the right advisor is not an easy task due lacks of lecturer in this campus and the lecturer are fully booked for this reason I almost use whole week around in the campus to find a supervisor and at last I went to see Mr. Suhairi Rizuan Bin Che Ahmad my Power Quality lecturer after my friends said he still available for accepting another 1 student. He agreed to be my supervisor and he give the FYP tittle which is Smart 12V Micro Hydro Generator.

This is some introduction my project.

Smart 12V micro hydro generator, its a renewable, clean and cost efficient to compare to others source. the idea is implement in the house where the water tank supply the water through the pipeline. In the pipeline the generator is installed to produce the voltage which is 12V dc without disturbing the water flow in each channel. the voltage produced is connect to the load in the house such as charger, LED or any small electronics application.


CONCLUSION:
From this week, I can conclude that the objective is successful without so much trouble. I think the title proposed is very suitable and related to my study area which is electrical.

Thursday 22 March 2012


Introduction



Hydropower is based on simple concepts. Moving water turns a turbine, the turbine spins a generator, and electricity is produced. Many other components may be in a system, but it all begins with the energy already within the moving water. Hydropower is the combination of head and flow.



Both must be present to produce electricity. Consider a typical hydro system. Water is diverted from a stream into a pipeline, where it is directed downhill and through the turbine (flow). The vertical drop (head) creates pressure at the bottom end of the pipeline. The pressurized water emerging from the end of the pipe creates the force that drives the turbine.



More flow or more head produces more electricity. Electrical power output will always be slightly less than water power input due to turbine and system inefficiencies. Micro hydro power is probably the least common of the three readily used renewable energy sources, but it has the potential to produce the most power, more reliably than solar or wind power if you have the right site. This means having access to a river or creek that has a high enough flow to produce useable power for a good part of the year.



Many creeks and rivers are permanent, because they never dry up, and these are the most suitable for micro-hydro power production. A micro hydro turbine can take several forms, the most widely recognized of which would be the water wheel, used extensively for grain grinding up until this century. Waterwheels are still used in some situations that do not require a fast-spinning turbine, such as for pumping water. However, other types of turbines have become quite common.



Hydro electric generating plants come in many sizes from huge plants that produce more electricity than most countries can use, to very small plants that supply electricity for a single house. A hydro electric plant which supplies electric power in the range from 15 kilowatts to 15, 000 kilowatts is called mini hydroelectric or mini hydro. Other phrases that mean the same thing are “small-scale hydro” and “small hydro”.



Fifteen kilowatts is about amount of power used by seven or eight houses in the industrial countries or be a very small manufacturing plant or it can provide lightning and other basic services for a village of 50-80 houses. Fifteen thousand kilowatts is enough for medium sized town. Hydro plants which are larger than 15,000 kilowatts are usually called “large hydro” or “conventional hydro” plants, but there is no sharp line dividing “mini hydro” from “large hydro”. All mini hydro and large hydroelectric plants use similar machinery, and must be designed by trained engineers. Both types of plants are also fairly expensive. Because of this, mini hydro plants are not well suited to village level development in most cases, a larger organization such as town, a collection of village or an industrial plantn is usually needed.


Other type of hydro plants, called “micro-hydro”, is better suited to village level development and local self help projects. These plants are usually smaller than 15 kilowatts and can be built by people without much special training, using mostly local materials and skills. Micro hydro plants are usually very low in cost but they are less efficient and the quality of the electricity is not as good. Micro hydro plants are suited to running lights, small motor or any small electrical appliances which did not need high voltage to on. Micro hydro power is another option of gathering electric power from moving water sources. By using small water turbines from a river or stream, individual can gather consistent power from the water. This is why this project has been selected for this final year projects.



Objective



The aim of this project is provide the opportunity for students to apply and integrate the theoretical knowledge and principles taught in the course in solving technical problem. It also provides the opportunity for the students to demonstrate independence and originality as well as to plan and organize a project over a certain period of time.


A propose to design and construct the smart 12v micro-hydro generator system for pre commercialization. These projects focus on electrical and mechanical system. The student will study on types of blades and selection of the generator motor. The objectives are:




· To research and study for development of micro hydro generator system.


· To design suitable micro hydro generator to implement to the area of the project for pre commercialization.


· To construct functional system of this project.




The main function of the system is to store the generated power by means of battery charging for future use particularly during electricity faulty or blackout in the resident area. However, this research is conducted to show the potential of the water in resident can be an alternative renewable energy.




Micro-Hydro Generator Components




1. Turbine - is responsible for converting the motion of the water to rotational energy. The type of turbine to be used will depend greatly on the type of water source to be harnessed. If it is of high head/low flow, typically a pelton wheel type turbine is used. If it is of low head/high flow.




2. DC generator - converts the mechanical rotation of the turbine into direct current electricity.




3. Inverter (optional) - converts the DC electricity into AC electricity. There are some cases where a generator which produces AC electricity is already used.




4. Batteries - Batteries are an integral part of the self-sufficient energy system. Lead-acid, deep-cycle batteries are usually used in hydro systems. Deep-cycle batteries are designed to withstand repeated charge and discharge cycles typical in renewable energy systems. Ideally, lead-acid batteries should not be discharged more than about half their capacity. Alkaline batteries, such as nickel iron and nickel-cadmium, can withstand complete discharge with no ill effects




5. Electronic Load Controller
- is the most important addition to the micro hydro design that simplifies greatly the creation of a steady flow of electricity. The Load controller has made it possible to automatically regulate the electricity generated, even when the speed of the flowing fluid varies.



Micro Hydro Generator benefits




Efficient energy source


It only takes a small amount of flow (as little as two gallons per minute) or a drop as low as two feet to generate electricity with micro hydro. Electricity can be delivered as far as a mile away to the location where it is being used.



Reliable electricity source


Hydro produces a continuous supply of electrical energy in comparison to other small-scale renewable technologies. The peak energy season is during the winter months when large quantities of electricity are required.



No reservoir required


Microhydro is considered to function as a ‘run-of-river’ system, meaning that the water passing through the generator is directed back into the stream with relatively little impact on the surrounding ecology.



Cost effective energy solution


Building a small-scale hydro-power system can cost from $1,000 – $20,000, depending on site electricity requirements and location. Maintenance fees are relatively small in comparison to other technologies.



Power for developing countries


Because of the low-cost versatility and longevity of micro hydro, developing countries can manufacture and implement the technology to help supply much needed electricity to small communities and villages.



Integrate with the local power grid


If your site produces a large amount of excess energy, some power companies will buy back your electricity overflow. You also have the ability to supplement your level of micro power with intake from the power grid.
