Course purpose

The aim of this course is to further equip students with knowledge in power system protection and monitoring. The first part of the course will cover fault analysis, symmetrical components, power system grounding techniques, relay instrumentations, protection of distribution system, protection of transmission system and protection of generators, bus-bars and transformers. The focus of the first part is on techniques of applying and setting protective relays. The second part of the course will cover power system measurement techniques, SCADA/EMS design and functionalities in the control room, power system state estimation techniques and its roles in power system operation, and wide area system monitoring and control using phasor measurement units. The course will discuss the challenges of renewable energy generations on power system protection and possible solutions. Going hand-in-hand with lectures, the students will also learn from working with computer simulation projects as well as laboratory demonstration.

Learning objectives and syllabus

Learning objectives:

i) with regards to the knowledge gained:

• Model power systems using symmetrical components and calculate fault currents for unbalanced faults for a simple network.
• Propose grounding methods for various type of grids (e.g. rural MV cable system) and evaluate their effects on faults currents.
• Evaluate the effects of magnetic saturations of relay instrument devices on measurement accuracy and relay’s performance.
• Propose protection schemes (e.g., overcurrent protection – non-directional and directional) for distribution systems for various grid structures and perform protection coordination studies and define relay settings.
• Choose protection schemes (e.g., distance protection) for transmission systems and perform protection coordination studies and define relay settings for various conditions (e.g., considering parallel lines, in-feeds, high fault resistance, etc.)
• Propose protection schemes for generators, bus-bars and transformers and determine correct relay settings.
• Describe the main the roles of SCADA/EMS in operating power systems, its functionalities and perform calculations of power system states based on measurements.

ii) with regards to the skills developed:

• Simulate the power system in faulted conditions and analyze the results for various system configurations using a specialized power system protection software (Computer Aided Protection Engineering -- CAPE).
• Carry out protection coordination studies and define relay settings for distribution and transmission systems a using specialized power system protection software (CAPE).
• Collaborate to work in team to manage computer projects.

Study plan

Examination form

The examination is based on a closed-book written exam and submitted project reports. Students must have the project reports approved in order to pass the course. The final grade of the course will be based on only the final examination and with the normal grades of 5, 4, 3 and U (fail). Only Chalmers approved calculators will be used in the exam.
