Project Summary

Normally, a single power source (i.e., WAPDA) is mostly used in houses or other areas. However, with an increasing number of population, there is a need to move towards renewable sources. At the same time, continuous supply of energy is also required without interruption even if some fault occurs in the utility. Therefore, there is a need of advanced automation system that controls more than one source (i.e., utility and DG/Solar/Wind, etc.) and provides an uninterrupted supply of energy even in the presence of a fault. If there are some faults that are related to supply sources such as over voltage and under voltage, the system automatically shifts toward other available energy source enabling the uninterrupted power supply to the customers. In this project, a fully automatic protection scheme for smart grid is developed and implemented, which provides continuous energy to the customers in the presence of a fault in the utility. In this project, current sensor, potential transformer, and Arduino are used to detect, control and switch the supply source and maintain a continuous supply of power to the load in the presence of faults.

Project Objectives

The objective of this project is to design a fully automatic protection scheme for a smart grid.

Project Implementation Method

In this project, two supplies are used. The first source is utility and the second source is battery charged by solar. If the faults occur in the system, the system will sense it with the help of sensors and then it will operate according to the given condition to the controller. In this project when the overvoltage and under voltage faults will occur the system will shift towards the battery. When the fault is removed from the utility, the system will automatically shift towards utility from the battery. In the case of overcurrent fault, the load will be disconnected from both the utility and the battery.

Benefits of the Project

• Protection of the sensitive load from faults in smart grid applications
• Fully automatic system
• Protection of the system from the fault current
• The circuit breaker is changed with programmable relay
• No human effort is needed in switching the circuit
