Induction motor which is an induction machine

can be operated as generators (induction

generators), generator madefrom a generatorwhich is made of an induction motor is very

advantageous for use in low-scale power plants

such as MHP. The advantages of this generator

is a simple construction does not require a brush(cage rotor), economical, low maintenance, and

do not wear a DC amplifier (djoekardi, 1996: 2-

3).

BACKGROUND

BACKGROUND CONTINUE

INDUCTION MOTOR AS GENERATOR (IMAG)

1.Use mechanical transmision/gear box/vanbelt the efficiency decrease is high so the

power is small which can be transfered. Tosolve this problem we can reduce the

mechanical transmision by make the generator.

2.Low speed generator is exspensive.3. Induction generator is tested on waterturbines.

AUTHENTICITY OF RESEARCH

As far as the author of the final project titled MAKINGINDUCTION GENERATOR SINGLE PHASE SPEED 1000 RPMAS A POWER PLANT WATER TURBIN has never been done inSTTN-BATAN Yogyakarta. A similar study conducted by Anur

Rahmad Yusuf, Nuclear Tecnophysics Programs STTN-BATANin 2011, with the title DESIGN OF LOW SPEED 3 PHASEGENERATOR USE INDUCTION MOTOR and similar been doneby the thunder of Gilang Gemuruh Yusufiel Ula, Programs ofNuclear Tecnophysics STTN-BATAN in 2011, entitled MAKING1 PHASE INDUCTION GENERATOR USING INDUCTION MOTOR

3 PHASE 3 / 4 HP. But in the research studies were not discussed about the

issue of water as a power plant turbine induction asgenerator drive 1000 rpm spin.

PROBLEM FORMULATION

How is the concept which used in change

induction motor to be generator. What are differences between output of

generator and the result of generator design.

How to make the rotation of 1000 rpmgenerator induction with three phase induction

motors to be used as a water turbine powerplant.


7/21

In this study, the authors limit the issues to be

discussed is the motor that will be converted into

single-phase generator is three- phase induction motor

with 1000 rpm spin and output power 3 / 4 HP,

Induction Generator Control (IGC) which is used for

testing in the Lab's electric STTN-BATAN beforeinduction generator do testing to water turbin.

PURPOSE OF FINAL TASK

Find economical motor induction to been low

speed generator used as a water turbine power

plant.

Used be a training device for students in

Polytechnic Institute of Nuclear technology

especially for electro mechanics students.

THEORY

THREE PHASE INDUCTION MOTOR

If current stay in magnetic field , the

current will cause force , usually we

use left hand law.

Three phase induction motor formulas

F = B.i.l

F = force (N)

B = flux (Wb)

i = current (A)

L = long of wire (m)

Fig.1. left hand law

Induction motor basically has three important parts as follows (figure 2.1).1. stator: is part of silent and have a coil that can induce an electromagnetic field to the coil

rotor.

2. gap: an air gap. place the transfer of energy from startor to the rotor.

3. rotor: it is the moving parts due to the magnetic induction from the stator coils are

induced in the rotor coil

THE PROCESS OF GENERATING THE VOLTAGE AT THE

INDUCTION GENERATOR.

E= B L U

E = Voltage (volt)

B = flux (Wb)

L = long of wire (m)

U = speed of generator (rpm)

n = 120.f/p

n = speed of generator (rpm)

f = frequency (Hz)

p = number of poles

to generate voltage in

output terminal

generator, in this case

the supplier of reactive

power is capacitors,

Capacitor formula

with:

Qg = required generator reactive

power (VAR)

U = the phase-phase voltage (volts)

f = frequency (Hz), C = capacitance(F)

At the time of induction machine slip a positive value as the

motor operates, whereas a negative value when the slip of

induction machine operates as a generator.

HYPOTESIS

Based on literature review and theoreticalfoundation that has been presented above, thewriter can make a prediction or tentativeconclusions as follows:1. Can be made single phase induction generatorusing speed 1000 rpm from 3 phase inductionmotor HP.2. Testing can be done to get the specifications of

the induction generator are made.3. By calculation and test characteristics of thegenerator will get the value of the capacitor with1000 rpm rotation required.
