Course content

Introduction: Introduction to the basic characteristic features of energy carriers such as electricity in power systems and heat in hydronic systems. Emphasis is placed on similarities and differences between them, and how they can be effectively utilised in supplying the various energy requirements.

Main Modules:

1. Analysis of electric power systems under steady state conditions. This includes:

- Three-phase systems and their equivalent per-phase representation

- Voltage drop, losses and compensation in high voltage transmission networks

- Transformers – characteristics and equivalent circuit

- Per unit systems

- Load flow studies.


2. Sizing of hydronic systems - district heating and cooling: General principles of design of pipe systems, pressure drop, pumping systems, and expansion and safety systems.


3. Gas and transportation of gas: Resource overview, types and properties, energy chains from gas wells to the end-users, purification and processing, pipeline transportation, LNG technology, perspectives for gas utilisation in Norway.

Learning outcome


After completing this course, the students shall:

- have basic knowledge about transmission of electric power (active and reactive power, three-phase), district heating, and natural gas.

- understand the most important physical and technical characteristics of these energy carriers.

- know the basic methods for analysis of energy flow in networks.



The students shall be able to:

- perform power flow calculations

- size district heating network.


The students will also have increased their abilities to:

- work independently and in groups.

- use instruments and equipment in the laboratory.

Learning methods and activities

Lectures. Compulsory exercises, laboratory and project work in groups. The project work includes both district heating and power systems. The project must be submitted to gain admission to the final examination.

Compulsory assignments

  • Øvinger
  • Laboratoriearbeid

Further on evaluation

Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (70%) and project work (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
If there is a re-sit examination, the examination form may change from written to oral.
In the case that the student receives an F/Fail as a final grade after both ordinary and re-sit exam, then the student must retake the course in its entirety. Submitted work that counts towards the final grade will also have to be retaken.
Permitted examination aids, support material code D: No printed or hand-written support material is allowed. A specific basic calculator is allowed. In addition, calculator Casio fx-991EX is allowed.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.

Course materials

Lecture notes. Handouts.
