This course will focus on design of transmission and distribution protection schemes. This will include fundamentals on protection, relay design and protection schemes for transmission lines, transformers and bus. Additionally the course will focus on settings of feeder and transformer protection schemes, and selection of current and voltage instrument transformers for those protection schemes. The issues surrounding power quality and how these affect power systems will be also addressed. This will include measurement and modelling techniques to identify power quality problems and mitigating techniques. Impact of electrical overstress on the design and operation of power systems and electronic equipment will be discussed and protection systems will be built to "eliminate" equipment malfunction and damage due to electrical overstress.
A single fault in a power system can cause outages for thousands of civilians. In this course, we will explore how to protect power systems against such events, through the design of power system transmission, as well as distribution level protection schemes. This will include fundamentals on protection, relay design and protection schemes for transmission lines, bus,ﾠtransformers, reactors and generator, as well as the impact of distributed generation, e.g. reverse power flow, on existing protection schemes. Additionally the course will focus on selecting current and voltage instrument transformers for specific settings of feeder and transformer protection schemes. To apply this learning to the real world, students will also have the opportunity to participate in practical simulations and hardware labs, as well as a series of lectures on industry practice conducted by experienced professionals. In previous years students highly appreciated the content covered in this course. To further improve practical knowledge a field visit for interested students may also be available this year.
