Course specific prerequisites

ENM066 Advanced power system analysis, or equivalent.


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 experiments.

Learning outcomes (after completion of the course the student should be able to)

i) with regards to the knowledge gained:
  • Calculate fault currents for unbalanced faults using of symmetrical components for a simple power system.
  • Propose grounding methods for various type of grids 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 relay settings and coordination study.
  • Choose protection schemes (e.g., distance protection) for transmission systems and perform relays settings and coordination study 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 and perform unbalanced fault analysis and analyze the results for various system conditions using a specialized power system protection software (e.g., CAPE).
  • Carry out relay settings and coordination studies for distribution and transmission systems a using specialized power system protection software (e.g., CAPE).
  • Develop a state-estimation model using GAMS and evaluate the impacts of measurement errors in the results obtained. 
  • Develop a measure for voltage stability improvement based on wide area monitoring using PSS/E and evaluate its performance under various system conditions. 
  • Collaborate to work in team to manage projects and lab experiment.


The course will cover the following topics:

Part I: Power system protection and grounding techniques
  1. Symmetrical components and unbalanced faults
  2. Power system grounding techniques and effects on faults currents
  3. Relaying instrumentations: voltage transformers, current transformers, and effects of saturations
  4.  Protection of distribution systems (e.g., overcurrent relay)
  5. Protection of transmission systems (e.g., distance relay)
  6. Protection of generators, bus-bars and transformers
Part II: Power system monitoring
  1. Measurement requirements and techniques in power systems
  2. SCADA/EMS design and functionalities
  3. Power system state estimation
  4. Wide-area monitoring and control using phasor measurement units


The course consists of 20 scheduled lectures (20x2 hours), 14 tutorials (14x2 hours), 2 laboratory experiments (2x2 hours) and 7 computer project consultations (7x2 hours).


Lecture handouts will be distributed electronically on the course website. Lectures are mainly based on the following reference books:

Examination including compulsory elements

The examination is based on a traditional closed-book written exam and submitted laboratory and project reports. Students must have the reports of lab and project 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).
