Objectives:Students understand basic principles of asymmetrical steady state behavior in components electrical energy systems. Furthermore they understand basic principles of asymmetrical supply of symmetrical energy systems as well as punctual asymmetrical systems fed symmetrical.
Students are able to build and to calculate single line models of specific asymmetrical situations in electrical energy systems.
Students are able to differ between positive, negative and zero sequence and know about specific differences.
Course contents:The lecture starts with an introduction in transformation into positive, negative and zero sequence and gives a brushing-up of the knowledge in single line representations of components in electrical energy systems (supply, loads, lines, transformers). The behavior of these components is investigated theoretical in the light of asymmetrical operation. Their single line representations are enhanced by reflecting these effects.
Based on these component models basics in modelling of asymmetrical steady state energy systems by use of single line diagrams are shown. Basic principles of asymmetrical supply of symmetrical energy systems as well as punctual asymmetrical systems fed symmetrical are considered.
The focus in punctual asymmetrical systems is on single phase to earth faults and consequential on neutral point treatment.
