FAULT DETECTION IN TRANSMISSION LINE USING IOT

Electrical power is transmitted from the generation plant to end-users at distant locations through the transmission line. These lines are exposed to various environmental conditions and faults may occur causing power interruption to end-users, damage to the power system. Fault location detection has been the main objective of power system engineers in transmission and distribution systems. Identification of fault source is a tedious task fast fault detection can help to protect the equipment before any significant damage to the equipment.The transmission line runs hundreds of kilometers, if any fault occurred in between transmission lines so it is hard to locate immediately and it is exhausting work to locate them. The exact fault location can help the serviceman remove persistent faults and locate the areas where the faults occur regularly, thus reducing the occurrence of faults and minimizing the time of power outages. The paper is intended to detect the location of the fault in the transmission line using IoT and the same is transmitted to the control center, an engineer through the GSM technology in the form of an SMS alert. The project used MATLAB Simulink to simulate generally occurring faults and detect them. Simulation results show that the proposed algorithm gives satisfactory results and will be very useful in the development of a power system protection scheme.
