Overview
Modern society cannot function without a reliable supply of electricity. However, an electrical power system that is completely free from failure is neither economically justifiable nor technically feasible. A power system or some part of the power system will, under certain abnormal circumstances, become faulted and as a result cease to operate as intended. A protection system, in the event of a fault, is required to maintain safety of personnel and members of the public, minimize damage to the power system, minimize interruption of supply and help maintain quality of supply. This course will help students develop the skills needed to design and carry out performance analysis of protection systems.
In this course the fundamental concepts, principles and methodologies associated with power system fault analysis and commonly used protection schemes shall be analysed and studied. Upon successful completion of this course, students will have an understanding of key power system protection performance and operational concepts as well as how these systems are implemented within a practical power network.
Course learning outcomes
- Explain the principle of operation of components used for implementing protection systems;
- Identify the key factors that influence the design of typical protection systems;
- Carry out quantitative analysis of the performance of typical protection systems;
- Devise protection schemes that are appropriate for particular applications.
