The development of the Power Sector in the state of Meghalaya is presently moving in the right direction so that the availability of affordable, reliable and quality power is ensured to the people

of the state in the near future.

Understanding the importance of Power as a prime mover for the development of the State, the Government had initiated a number of measures to develop the state power sector to its fullest potential for the prosperity of Meghalaya and its people.

In the past, there has not been any proper power development planning and this has resulted in making Meghalaya a power deficit state.

The government feels that the vast hydro potential of about 3000 MW needs to be harnessed at the earliest. Thrust has been made in the development of infrastructure of the transmission network, so

that the state can evacuate its future generation surplus and also to eventually draw its share of power from the Central Power sector in the North East region. There is an intention to explore and

possibly tap the power potential of up to 400MW from small hydropower generation alone.

It is hoped that in the near future the state of Meghalaya will once again regain its status of a power surplus state.

TECHNOLOGY

HSPP benefits from the rich experience of Honda Motors, Japan, the second

largest engine manufacturer in the world, because of their strong emphasis on

R&D and in-house technical innovation. India’s first LPG based Generator along

with the Super Silent Key Start Generator portable kerosene generators are some

of the products which exemplify Honda’s pursuit of technological excellence. The product range of Generators conforms to the most stringent phase II Noise &

Emission norms as laid down by the Central Pollution Control Board (CPCB),

Government of India.

CERTIFICATION

Govt. of Meghalaya (GoMe) decided to reform and restructure its power sector with the

objective of creating the conditions for the sustainable development of the electricity supply

industry and improving the efficiency and quality of services in Meghalaya. The ultimate goal of

reform process is to ensure that

a)Electricity is supplied under the most efficient conditions in term of quality and cost to support the economic development of the State; and b)The power sector ceases to be, through its Electricity Board, a burden on the State’s budget, and

eventually become a net generator of financial resources.

Govt. of Meghalaya after deciding to reform and restructure its power sector intends to corporatize its power sector and has also to establish an appropriate Electricity Regulatory Commission.

METHODOLOGY

Stage I (Sumer) hydro power station capacity 4 x 9 = 36 MW : (1)Operation of the power station

4 AE + 4 JE + 4 control room operation + 12 technician. However in stage I control room is two stories above the turbine floor. In-between control room

and turbine floor an intermediate floor where 11 KV switch panel are housed block the free passage. Therefore one JE per shift is at present necessary to coordinate between turbine floor and control room. Apart from that communication from all the power station toload despatch center is

now through the stage I power station since the direct link toload despatch center from other power stations have been disconnected, hence communication is also an added

responsibility of this power station which is borne by the special manning. As such operation manning at stage – I should be 4 AE + 8 JE + 4 control room operator + 12 technician.

(2)Maintenance of stage I

1 JE + 1 Electrician + 1 fitter + 6 technician + 1 crane driver Therefore proposed manpower 4 AE + 9 JE + 4 control room operator + 1 electrician + 1 fitter + 1 crane

driver + 18 technician. Total 38. Existing manpower 5 AE + 8 JE + 25 technician. Total 38.

Stage II (Umsumer) hydro power station capacity 2 x 9 = 18 MW.

(1)Operation of power station:

Same manning :

4 AE + 4 JE + 4 control room operator + 12 technician.

(2)Maintenance of stage 2:

Maintenance also should have the standard m anning of 1 JE + 1 Electrician + 1 fitter

+ 18technician + 1 crane driver.

About Plant

There are two big pipes are coming from a height ,they are full of water contain they are divided

into four parts due to which four motor connected for more electricity production then the water

falls on the turbine due to which turbine rotates so due to rotation of turbine Electricity produces.

Light is depends on the rotation of turbine and rotation of turbine is depends on the pressure of

water falls .

Main components of Power Plant

1. Power Plant Room

2. Switching room

Power plant

The power is the main source of any organization. That is the first requirement of any

organization is the input. The main source of this exchange is the AC supply. This act as the

feeding point of power to all other sections. To start every machine the first supply is from a dc

source, but it is not the main source of power supply. It is used only for the excitation needed by

the machine to start and then it is converted into ac power supply.

The equipments used in the power plant are :-

Sump tank

Emergency cooling machine

Immersing machine

Air compresser pump

Automatic voltage regulator

Service station transformer

Induction motor

Turbine

Generator unit

Power line communication carrier

12

Sump tank

It has two different coloured pipes connected to it. They are yellow and green pipes. The

yellow pipe contains oil and the green pipe contains water. When the machine starts it

pushesthe water further. It is automatically control.

Emergency cooling machine

This machine is used to cool down the temperature within the machine when it gets heated up. It is

handled manually. When the temperature inside the machine rises, the steer is rotated and cool

water is supplied around the part which becomes heated.

13

Immersing machine

This machine is used to maintain the water level to push it further. When the water is below the

level needed, then some weights are immersed to raise the water level to make it function. When

the water is above the level needed, like at times of rain or flood, the weights are taken out to

decrease the level of water.

Air compressor pump

It is used to maintain the pressure inside the container containing 10 kgs of air/vaccum and 20 kgs

of oil.

14

Automatic voltage regulator

The AVR (automatic voltage regulator) as the name suggests it regulates the voltage. It is set so to

reduce the work load the workers i.e. they don’t need to check the voltage on which the machine

works. It will automatically regulate as per the requirement.

Induction motor and turbine

The motor used was a 3 – phase induction motor. It consists of a stator and a rotor. It works on the

principle of electro-magnetic induction. The stator is made by joining many copper rings which

behaves like a hollow sphere. The wires are wounded in such a way that when the current passes

one part behaves as the north pole and the other as the south pole.

The rotor is the rotating electrical components, it consists of group of electromagnets arranged

around the cylinder with the poles facing the stator poles. It is located inside the stator. As the

magnetic field of the stator alternates due to the effect of ac power supply, the induced field of the

rotor gets attracted in.

15

The turbine is rotated only when water hits it with a pressure, it is connected to the generator

where the power is generated.

Generator room

There are many units of generators. Since a large amount of power is generated from the power

plant, therefore, a no. of units are there to keep a record of the power generated.

Power line communication carrier

They show the arrangement of line networks to supply power to various cities. The lining on the

top is for the main bus. The one below it is for the auxillary bus. Bus couplers are there which are

used in operating the machine from the power station if the machine has been transported

somewhere.

Conclusion

Engineering student will have to serve in the public and private sector industries and workshop

based training and teaching in classroom has its own limitation. The lack of exposure to real life,

material express and functioning of industrial organization is the measure hindrance in the student

employment.

In the open economy era of fast modernization and tough competition, technical industries should

procedure pass out as near to job function as possible.Practical training is one of the major steps in

this direction. I attended the industrial visit at Meghalaya Electrical Corporation Limited, Shillong

which is one of the best known power generating companies of India. The training helps me in

gaining in depth knowledge of the working of various machines and equipments in power

generation.

In the end, I hereby conclude that I have successfully completed my industrial training on the

above topics.
