Faglig innhold
Course Objective: Proliferation of non-linear and time variant loads in the power system calls for advanced compensation equipment and operation aimed at improved power quality and efficient use of resources. Power electronics is one candidate solution provided that use of the device is done on the basis of a proper understanding of the complex problem. The aim of the course is to provide a theoretical platform for developing a solid criteria for compensation of the non active component of the power in the context of the power theory discussions.
Syllabus:
Introduction- Historical review of the reactive power theory for non sinusoidal conditions. Presentation of the updated discussion in the scientific community.
Importance of reactive power control in electric power systems. Advantages and disadvantages of different types or reactive power compensation systems: passive/active, fixed/regulated series/shunt compensations.
Principle of Reactive Power control. General capabilities of voltage source converters and current source converters in providing reactive power (HVDC, variable speed motor drives, distributed generation interfaced by power electronics). Evaluation of distributed versus centralized compensation.
Discussion of the following reactive power comensating devices:
- Static Var Compensator(SVC): Principle of operation, configuration and control capabilities
Static Compensator(STATCOM): Principle of operation, configuration and control capabilities
Stability Issues:
- Issues of steady state and transient stability control with SVC and STATCOM: SVC, STATCOM control strategy, rating considerations
Læringsutbytte
To acquire a good understanding of the capabilities of power electronic technology for reactive power compensation,in the light of the instantaneous power defintion theory.
Læringsformer og aktiviteter
The course will be based on introductory lectures followed by discussion of selected papers by each participant of the course. The dynamics will be the following: a list of selected papers will be given at the begining for each student to present during one lecture and to be discussed openly by each participant. The student will have assigned a paper and will have to prepare the presentation/discussion of that paper according to a calendar that will be provided in the second lecture day.
The exam will consist on the preparation of a scientific paper in which the knowledge acquired during the course will be implemented by the student using as platform for the discussion his/her PhD research topic. The course is given every second year, next time spring 2012.
