Smart Microcontroller-Based Integrated Monitoring and Protection System for Three-Phase Power Transformers

MSc level project, School of Science and Engineering

Abstract

Three-phase power transformers are important equipment in AC electrical power systems. In this project, a smart microcontroller-based integrated monitoring and protection system for three-phase power transformers will be developed theoretically and an experimental prototype model (software and hardware) will be designed, implemented and tested.

Description

Three-phase power transformers are important equipment in AC electrical power systems. They change the voltage to higher or lower levels for power transmission, distribution or delivery. It is very important to avoid power transformer interruptions and protect it from damaging faults by minimizing their frequencies and durations.

Many protective relaying techniques have been developed for power transformer protection such as overcurrent relay for protection against overloading and phase faults, differential relay for zone-based protection against phase and earth faults, earth fault relay for protection against earth faults and gas-actuated (Buchholz) relay for protection against slow developing faults in oil immersed transformers. 

The smart grids vision utilize real time information and communication technology applications with intelligent-based techniques for protective relaying. A real time monitoring, with processing, of the three phase voltages and currents, temperature and gas-actuated relay signals might enable early prediction of some specific interruptions. Furthermore, the integration between different protective relaying techniques, using advanced microcontrollers capabilities, could form an integrated intelligent protection system. 

The main goal of this project is to propose, or develop, a smart microcontroller-based integrated monitoring and protection system for three-phase power transformers. An experimental model using microcontroller will be developed. A real time monitoring system with suitable alarming functions will be proposed, and an integrated protection system covering all standard relay functions will be designed, implemented experimentally and tested using different types of test faults.

Methodology and Time plan:

 

  1. Literature Review (2 months):A review on the standard protective relaying techniques that have been developed for power transformer protection such as overcurrent relay, differential relay, earth fault relay and gas-actuated (Buchholz) relay, and the microcontroller based application in power transformer protection.Chapter 1 (introduction) and chapter 2 (literature review) should be written and submitted.
  2. Smart Monitoring and Protection System (3 months):A smart microcontroller-based integrated monitoring and protection system for three-phase power transformers will be proposed or developed. A mathematical model with suitable programming functions using microcontroller will be designed and implemented, including a real time monitoring system with suitable alarming functions and an integrated protection system covering all standard relay functions.Chapter 3 (Smart Monitoring and Protection System) should be written and submitted.
  3. Experimental Implementation and Testing (3 months):An experimental implementation of the proposed microcontroller-based integrated monitoring and protection system using microcontroller will presented. The prototype model will be tested experimentally using different types of test faults.Chapter 4 (Experimental Implementation and Testing) should be written and submitted.
  4. Thesis Submission and Presentation (2 months):Conclusions should be written and all thesis sections should be completed.The full thesis should be submitted and presented.
