Project Summary

According to the surveys we observe that in Karachi there are so many industries which are not aware of the process of self-generation that's why we choose this project for the betterment of the industries which are not aware of this idea of self-generation and it's the responsibility of the
engineers to always take a step for the betterment of the industries of their country because of industries
make the back of any country stronger now the basic concept behind this is to promote the idea of self-generation among the industries in this idea first we work on the procedure of synchronization now the synchronization of any generator or machines needs to do the following step during the process of synchronization and these steps are as follows.
1.Phase sequence
2.Phase Angle
3.Voltage amplitude
4.Frequency
There is a different method of synchronization but we use the synchroscope method in our project because
it can be done manually which are easily understand and cheap in cost as compared to another method so
industries can easily purchase and easily implement this which can save their cost and the other things are
to managing the load it is very important for the industries that in case of any load shedding or blackout there most priority load is always on running and never shut down so it means that there most priority load is 24/7 on which is a big relief for any industry. now we will discuss some important
background about the synchroscope which is very important so basically the synchroscope is the method of manual synchronization which displays the frequency of generator or machine and the pointer of the synchroscope observe the speed of generator fast or slow with respect to the system and then needle slowly approaches the in-phase point and the synchronization occurs.

Project Objectives

in the world with full of technology we observe something new to help the  industries in our manner that's why we suggest this project the main purpose of this project is to provide the concept/idea of self-generation to the industries although many of the industries have their own generation many have not so we are working for those industries which have not aware the idea of self-generation yet so as we survey many industries in Karachi we observe that there is a need for our idea in Karachi to provide them the opportunity to make them industries self-generated now there are some most important point that why we choose this project and these points are given below
1-if any industry generate their own power its mean that industries save the huge
amount of cost which is really a big relief to the industry.
2-in case of any shut down there is some power always save to give continues supply to high priority load and this condition only can be done if the industry has its own generation.
3-mostly blackout condition occurs in those industries which have not their own generation if the industries want to save from this condition the self-generation must be their priority.
4-continues supply becomes the most important issue nowadays because whenever any shut down occur in industries their continues supply break immediately and it takes some time for recovery so this issue can be resolved by this project.

Project Implementation Method

De-Lorenzo Alternator:        

We are using 1KVA 3 phase alternator side by side with KE. This alternator is separately excited by a 1.6 KW motor. The alternator has a capability to deliver 1.67 amp of current in star configuration while 2.9 amp in delta configuration in a normal condition of 50 Hz frequency with 230 phase voltages and 380 line voltages at 3000 RPM.As it will be synchronized with KE and in fault condition gets unsynchronized.

Implementation:

We are using this device as to get our desired output. We will be syncing this alternator with KE and will observe the sharing of load through it. As to get proper synchronization we will be controlling it’s excitation to get the proper synchronization. And as KE and alternator gets properly synchronized we will observe the current sharing from both these devices according to the changing load. To introduce fault we will disconnect alternator from bus bar so as PLC could easily be performed its operation.

Panel 1 (synchronization Panel With Bus Bar):

synchronoscope:

As the name suggests synchronoscope is a device which is used for synchronization of two or more sources ( in our case 2 sources). it works on the principle of voltage, frequency and phase sequence. When all these parameters are set to the desired value the synchronoscope got synced. 

                             it has the number of red LEDs which got on and off in a cycle till it gets synced and the green light turns on. It also comprises of a number of other LEDs which shows the main voltages or bus voltages and generator voltages if they are on the synchronoscope or not.at the back of the synchronoscope consists of a number of contacts which are according to the phase sequences. As for the KE side, we use red and blue phase with 1 and 3 contacts of synchronoscope while 4 and 6 contacts will be used with red and blue phases of an alternator.

Implementation:

                           Synchronoscope or synchroscope is the device which we are using to get the proper synchronization of KE and alternator. As to properly get the result we are connecting KE and alternator from voltmeter and frequency meter to synchroscope as to check the voltages and frequencies of both the devices. And as they both get the same voltages, frequencies, and phase sequences, they ultimately synched with each other through synchronoscope

Benefits of the Project

Increased reliability and redundancy: Improving reliability and redundancy for both critical and non-critical loads. The system ensures that there is always constant power to critical loads, and if one of the generators fails, the load is supplied by the other one or more parallel unit.


Low cost of power generation: Cost of generation increases with generator size and is more for ratings above 600KW.This is due to the fact that the market for smaller engines is higher, hence more are manufactured, resulting in lower cost. Using several smaller generators becomes more economical than a single large generator.


Decreased light loading of the generator prime mover: In most installations, the load varies from time to time and it is common to have a generator running at 30% of its capacity when the load is low. This may cause wet stacking. The efficiency of the prime mover is normally higher when the load is between 75% and 100%, and a light load means that the generator operation is inefficient. Using a smaller generator increases efficiency, hence a cost reduction.


More control and savings on generating costs: The total amount of power supplied from several small generators is equal to the power supplied by one large unit. However, there is more control and balance in the smaller generators. One can balance the load over the different circuits, and decide on the power to generate at any particular time based on the load.

• The parallel system can achieve huge savings when all generators are operated above 75% of their rated load. This is the point at which generators use the minimum fuel.

Expandability and flexibility: The use of several generators makes it possible to supply a varying load without piling up costly units or spending too much on a big generator whose full capacity is rarely used. Generators can be added gradually as demand increases.

Technical Details of Final Deliverable

Setting up parallel generators is a complex procedure that requires a qualified electrical professional.

A well-designed system provides backup power and variable output. Using the correct paralleling switchgear helps the consumer to achieve the maximum output when the power demand is at its peak while providing the minimum output when the load requirements are low.
