1. INTRODUCTION
Nowadays, industries meet severe problems due to the
interruption of power supply from the line to ground fault,
which leads to a failure of transmission and distribution
system. Once the failure occurs in a transmission or
distribution system at the time estimating thelocationof the
fault is a difficult thing and also fault clearing takes a lot of
time. We know that the productivity of small industries
based on the availability of electric power. So, we need to
provide electricity to the small industries in an effective
manner to develop the economic condition of the country.
On another hand, some difficulties available in switchingthe
power supply between the feeders or transmission lines. Up
to nowadays, AB switches are commonly used to switching
the power supply by using human power. Which leads to
electric shock due to touch the potential phenomena in the
switching circuit. So, the objective of the paperisprovidinga
continues power supply by using an auxiliary feeder with
automated power line switching unit and ensure the safety
of human while in switching action with help of GSM control
unit. The automatic power line switching unit gets the
information from the different types of relay circuits to
monitor the transmission and distribution network for
performing the respective action to provide the continues
power supply. The GSM communication is the worldwide
range of communication, so we can changethepowerflowin
an electrical network where ever from in this world byusing
our GSM control unit.

[3] Author focus to implement the main objective of his
project is to prevent overloading of the transmission line
using the current sensor. Internet and wireless
communications have also been utilized in parallel withGSM
for home automation [4]. Among the cellular technologies,
GSM network is preferred for the communication between
the home appliances and the user due to its widespread
coverage [5]. For the power, system design and analysis
power flow analysis is used and MATLAB programming is
used for software package [6]. Conventional single pole and
three phases auto-reclosing techniques applied to extra high
voltage (EHV) transmission lines adopt ﬁxed time interval
reclosure techniques [7]. Controlled switching has been a
desirable method for stress reduction and in particular for
reduction of switching overvoltages, becoming an issue of
widespread interest to the utilities and manufacturers [8].
Transmission and distribution substations are installations
where the voltage, phase or other characteristics of the
electrical energy are changed as part of the final distribution
process [9].
3. BLOCK DIAGRAM AND DESCRIPTION
Here each unit of the system will be classified according to
the performance of the parts of a system such as automatic
power line switching unit, GSM control unit and switched-
mode power supply. The overall block diagramofthesystem
shown in Figure (1).
3.1Automatic Power line Switching Unit
Automatic power line switching unit gets the information
from the relay circuits to monitor the overall distribution
system performance. It has the following parts such as a

microcontroller (1), relays, Solid State Transfer Switch, LCD
controller and LCD display. The microcontroller (1) is used
to control and monitor the distribution system and the LCD
controller is used to show the current information aboutthe
system in the LCD display. Where the timer is used to
achieve a specific switching action within a specified time
interval. In this proposed system can make synchronized
switching action according to the program in a
microcontroller with help of a timer.
3.2 GSM control Unit
The GSM control unit has another microcontroller (2) and
GSM /GPRS V3 module. This GSM technology is used to send
and receive the SMS in this proposed system. When the fault
occurs in the system such time automatic power line
switching unit changes the power into the auxiliary feeder/
transmission line. Such time this GSM control unit sends the
fault information to the respective person. And also which
unit used to change the power line by using SMS at the
maintenance time of an electrical network. The
microcontroller (2) is used to execute the above mentioned
all things.
3.3 Switched-Mode Power Supply
The switched-mode power supply unit is used for
rectification and provides the required amount of power
supply to the all components such as automatic power line
switching unit and GSM control unit, because where all the
components are working with different power range in a
form of DC supply. So the switched- mode power supply is
the suitable one, to provide a power supply to achievebetter
performance from the automatic power line unit and GSM
control unit.

circuit breakers/switching circuits are mentioned in the
form of C.B-S.W. The above-mentioned block diagramshows

mechanism. The proposed system can manage up to ten
industries in an effective manner.
4. EXISTING METHODOLOGY
Electricity is the most important factor in the industries,
according to this approach we know that the productivity of
the industry based on the availability of electricity. So the
objective of the proposed system is to provide a continues
electricity to industries in an effective manner and also
ensuring the safety of the working person who works with
the distribution system.
Here, the proposed system has a two feeder to provide
the electricity to the industries such as Main feeder and
Auxiliary feeder. At normal operating condition electricity
only flows through the main feeder. The behavior of the
proposed system is monitored with help of microcontroller
(1) and different types of the relay. And also monitored
information is shown in LCD display by using display
controller.
When a fault occurs on themainfeederoperation, whichis
sensed by the microcontroller(1)thenthepowersupplywill
be switched to the auxiliary feeder in an automatic manner
for providing a continuous power supply to the industry
with help of switching devices (Solid State Transfer Switch-
SSTS). Then the system sends the fault information in the
form of SMS to the respective person who is the in-charge of
the distribution system with help of GSM technology for
clear the fault on the respective feeder in a frequentmanner.
In this condition information about the faulty feeder is
shown in LCD display with help of LCD controller. The timer
is used to achieve the synchronized switching action in this
proposed system. According to the above-mentioned
approach we can provide continuous power supply to
industries and also monitoringofthepowersystembecomes
wide range with help of GSM technology.
In the distribution system, manual switching
action of the power supply is an essential one at the
maintenance time. In many areas, AB switches are used to
achieve the switching action, which is sometimes leading an
electric shock. And also we know that Remote switching
action only possible in local area control. So,theGSMcontrol
unit is introduced in this system to ensure the safety of the
working person from the electric shock who works with the
distribution system and achieve the worldwide control
facility.

From the represented block diagram of the system, GSM
control unit has an individual microcontroller (2), GSM
module and separate switching circuit (SSTS) to achieve the
independent performance from the automatic power line
switching unit. When the working person wants to change
the power supply due to the personal requirement, such
time he sends the SMS to the proposed system toachievethe
required switching action. In this unit, the GSM module is
used for thecommunicationpurposeandmicrocontroller (2)
is used to process the received SMS to process and execute
the required action according to the SMS information. The
overall function of the proposed system shown in figure 2.
This system has Switched-Mode power supply to provide
the power supply for different type’s equipment in the
proposed system.
Fig.2 Flowchart representation of the proposed system.
From the above flowchart representation GSM
control unit has first priority to supply the electric power to
the industry. So, the manual switching through the GSM
technology is reliable and more effective. This proposed
system can monitor ten feeders at the same time.
5. PROPOSED AUTOMATION SYSTEM
The Proteus 8 software is used to simulate the
proposed idea of the system. Here the proposed system
mainly classified according to the performance of parts in
each unit.
 Automatic power line switching unit
 GSM control unit
Note: Here, proposed simulation diagrams represent the
distribution system fortwoindustriesandalsoeachindustry
is represented in the form of a lamp.
5.1 Automatic power line switching unit:
In this proposed system has two feeders to provide
an uninterrupted power supply to the industries. At normal
operating condition power supply only flows through the
main feeder. When a fault occurs on the main feeder such
time only power supply switched into the auxiliary feeder.
The automatic power line switching unit has a
microcontroller(1) to achieve the continuous monitoring of
the distribution system. Which gets parameters about the
distribution system from the different typesof relaycircuits.
And also which is paralleled with GSM control unit to send
the SMS to the respective person at the fault situations.
Fig.3 Automatic power line switching unit at the normal
operating condition.
The above-mentioned Figure (3) represents the circuit
connection and performance of the automatic power line
switching unit at the normal operating condition. When no-
fault takes place on the distribution system such time which
system gets positive logic of inputs fromtherelaycircuits. So
the power supplies troughs onlyonmainfeeders(M1,M2)to
the respective industries/consumer. In this condition the
proposed system displays on LCD display such as “MAIN
FEEDER 1 EN” and “MAIN FEEDER 2 EN” with help of LCD
controller.
If the fault is detected by the relay circuit on the
main feeders (M1, M2) operation, such time the automatic
power line switching unit transfers the electric power to the
auxiliary feeders (A1, A2). And also which system sends the
fault alert to the respective person with help of GSM control
unit. The following figure (4) describes the function
automatic power line switching unit when the fault occurs
on both main feeders.

Fig.4 Automatic power line switching unit at both feeders
is in a failure condition.
In this condition which system shows in LCD display
“AUXILIARY FEEDER1 EN” and “AUXILIARY FEEDER2 EN”
with help of LCD controller. Thus the overall function of the
automatic switching unit for two industries distribution
system modal was described in the form of tabulation in
Table (1).

When the feeder in good operating condition at the time
relay circuit sends positive logic (1) to the automatic power
line switching unit.
5.2 GSM control unit:
The GSM control unit is a part of the system,whichiscapable
of sending and receiving the SMS by using GSM module. It
provides the facility to control the distribution system
according to the requirement of the user by sendingtheSMS
to the GSM module. It is very useful to the respective person
who works with the distribution system. This has an
individual controller andswitchingcircuitstoimplementthe
required actions. The following diagram (5) represents the
GSM control unit circuit diagram.
Fig. 5 GSM control unit circuit diagram.
Here the performance of the system is programmed in the
controller like an automatic power line switching unit for
each comment as per the required in the GSM control unit.
This GSM module provides worldwide control facility so we
can control the distribution system where ever from this
world. This is secured from the unauthorized persons when
we use proper condition loop for the mobile number
checking program. When we implement the following loop
with GSM control unit, such time this system checks the
mobile number and it can identifywhichmessageisreceived
from an authorized person or not.
char phone_no[]="+************";
void receiveSms(const char * number ,const char * text)
{
if(!strcmp(number, phoneno))/*Mobile numberverification
{
// A body of the system program
}
}
When the GSM controlunitreceivesSMSfromtheauthorized
person mobile number as like “#SRN.indus1 on”. Such time
power flow takes place only on first industry main feeder.

Which is clearly shown in the following simulation diagram
(6).
Fig. 8 Simulation diagram for fire issue condition of the
proposed control and operational unit.
Similarly, the overall control strategy of the proposed two
industries distribution system described in the form of
tabulation with respective comment model in the following
Table (2).

Which system has the following constraints :
 We need an auxiliary power supply to drive the
overall proposed system.
