Project Summary

In today’s world, the technological trend of implementing “smart” technologies, fostered by the emergence of Cloud Computing and the Internet of Things (IoT), led to a transfiguration of ordinary devices and environments to “smart” entities. In this context, traditional electrical protection devices also tend to transcend and become “smart”, and consequently offer improved fault-detection and protection, remote monitoring and event notifications.By becoming smart, a home is embedded with ubiquitous computing equipment that connects all the household devices to one another and the Internet. A smart city also embeds in the urban landscape computers, sensors, cameras and other sensitive equipment operating in the background. In these circumstances, protecting the power supply grid against faults becomes even more important, given the increasing number of sensitive devices connected in the emerging Smart world.

The traditional electrical protection for residential, office and industrial buildings is based on classic circuit breakers tripping or fuses being blown when an overload happens, thus offering limited protection and warning. Also the traditional circuit breakers used for power system protection are usually designed to protect against a single power supply grid fault event. Thus Protecting the electrical power supply system against interruptions due to various faults is thus a main research concern.

In the proposed project we will design a multifunction power system protection device which will ensures the safety of consumers connected with the public grid supply by disconnecting the power supply in case of electrical faults like overvoltage, under-voltage, overcurrent, electrical arc and also send the data to server from where the user can control and monitor the status of faults. Also the proposed power system protection device will have an app through which user can easily monitor and control the device.   

Project Objectives

• To design simple combined type multifunction circuit for advanced fault-detection and protection through high-speed disconnection in the case of: overcurrent, overvoltage, under voltage, leakage current and electric arc.
• Real-time monitoring by sending recorded events to a Web server where the information is accessible through an online Web-based interface.
• Real-time notifications by e-mail and text messages to designated persons.

Project Implementation Method

The working principle of protection device is that whenever the threshold values for load decoupling exceeds in case of an electrical fault like  overcurrent, overvoltage, under-voltage, electric arc the microcontroller disconnect the load through the relay and send message to the user and also send data to the server from where user can access online. 

The proposed project scheme will be based on five phases which are described as follows: 

1. Theoretical Study of Components. 
2. Software Simulation. 
3. Experimental Set-up of Hardware. 
4. Programming the Modules. 
5. Testing.  

1.Theoretical Study of Components 

In this phase, a theoretical study of components will be made e.g., pin configuration of modules, input and output voltages of modules so as to decide whether the components selected can perform the desired task or a better module is to be selected. A better understanding of sensor study will also be made in this phase.

2. Software Simulation 

In this phase, after a theoretical study, the software simulation will be done using different software e.g. Proteus, MATLAB, etc.

3. Experimental Set-up of Hardware 

In the third phase, all the component’s modules will be combined to develop a prototype and initially tested.  If any malfunctioning occurs, troubleshooting and repairing will be made in this phase.  

4.Programming the Controller 

In the fourth phase, programming will be done for running the prototype. The controller will be programmed in this stage to achieve the objectives. 

5.Testing 

In the final phase, the developed prototype will be tested  in national institute of electronic (NIE) ,power electronic lab to check whether the fabricated project is working properly or not.

Benefits of the Project

The proposed power protection system has vast scope, it can be integrated in any smart environment like smart homes or smart cities for electrical safety by fast disconnection of the power supply in case of fault events like leakage current, overcurrent, electric arc, overvoltage.it not only allows remote monitoring and control of the coupling/decoupling feature, but also support real time notification and provides enhanced protection against wide range of electrical failures.  Similarly this protection system can also be used in multi-terminal dc grid for aerospace applications as well as in smart micro grids and aircraft power distribution protection system.
