Abstract :
The reliable operation of a power system largely depends on the fast and accurate detection of faults and the timely
restoration of supply. Faults in power systems are broadly classified as symmetrical and unsymmetrical faults, both of which
can cause severe damage to equipment, voltage instability and interruption of power supply if not properly handled.
This project presents the design and implementation of a symmetrical and unsymmetrical fault detection system with
an automatic reclosing circuit breaker to improve system reliability and continuity of service. The proposed system
continuously monitors line parameters such as voltage and current to identify abnormal conditions during fault occurrences.
Upon detection of a fault the protection circuit isolates the faulty section by tripping the contactor with relay.
An automatic reclosing mechanism is implemented to restore power after a predefined time delay, assuming the fault
is temporary in nature. This reduces the outage duration, improves system stability and minimizes manual intervention.
Simultaneously global system for mobile communication (GSM) communicates with the controller and sends the message of
the fault and occurrence of the system. Simultaneously MQTT dash (android application) is connected to the system server
through the cloud and personnel can monitor the active and real time data, therefore also can control through the dash
application changing its mode to auto or manual mode of operation. Secondly through the SMS command (0 or 1) we can
charge and trip the system therefore where charge is denoted as 1 and trip is denoted as 0. The developed system is suitable
for application in transmission and distribution networks where fast fault clearance and frequent supply restoration are
critical.
