Protection coordination of Mehran university of engineering and technology

Project Title

Protection coordination of Mehran university of engineering and technology

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

The power systems can be subjected to numerous cases of faults that can render them out of synchronism. Protection and technical feasibility are required for the efficient function of the power system. This study proposes such protection and techno-economic coordination for Mehran University of Engineering and Technology, Jamshoro (MUET). The electrical Layout of MUET has two main VCBs (Vacuum Circuit breakers) for protection purposes. The whole network gets disturbed when a fault occurs in any department. Therefore, the purpose of this study is to model a new system for MUET that contains protective devices and their coordination in order to enhance the efficient operation and reliability of the system.

Project Objectives

This research aims to the protection coordination of substations located at Mehran University of Engineering and Technology and the cost analysis of the proposed system. The objectives of this research are as below.

? To collect the data of each department of MUET.

? To model the electrical network of Mehran University of Engineering and technology by using ETAP software.

? To perform the short circuit and load flow analysis of the existing system of MUET.

? To propose a new system for MUET containing circuit breakers.

? To perform the short circuit and load flow analysis of the new network by using ETAP.

? Cost analysis of the electrical network of MUET.

Project Implementation Method

• Firstly, The MUET network will be modeled for a simpler study of the major interconnections in the network.
• The second step is to perform load flow and short circuit analysis.
• The third step is to propose some protective devices that are needed to make the system reliable.
•  The fourth step is to perform load flow analysis. Through load flow analysis, we can compute power flow at different points, voltage drops at various busbars, and power losses, and it can also indicate the loading condition of different equipment.
•  The fifth step is to perform short circuit analysis. This can help us to determine the short circuit current which could be 10 times greater than the load current. The short circuit analysis will provide us with the information we need to determine whether the power system components have the necessary interrupting capacity to protect the power system.
•  If an area with a fault is isolated from the healthy area, the system is considered stable. So, the ultimate step is to perform the protection coordination of Mehran University of Engineering and technology.
•  Cost analysis of the proposed electrical system of MUET.
• To design prototype 

Benefits of the Project

• To detach the live part from the healthy part.
• It enhances the efficient operation and reliability of the system.
• High rating equipment will not get damaged.
