NTNU Electric Power Engineering Smart grid ET8304 Instantaneous Power Theories and Compensation with Power Electronics Autumn 7,5
Course objective: Pervasive proliferation of non-linear and time-varying loads and distributed generation make the power system operate under conditions that are substantially different from traditional sinusoidal ones. This calls for advanced compensation equipment and coordinate operation to improve power quality and efficient use of resources. Power electronics is the best candidate solution, provided that the use of any device is based on a proper understanding of the complexity of the new scenario. The aim of the course is to provide a theoretical background to correctly approach the problem of reactive, harmonic and unbalance compensation, in the context of the power theory debate still open today.
Syllabus: -Introduction -Historical review of the main power theories for electric networks operating under non-ideal conditions.-Presentation of the updated discussion in the scientific community. -Correct definition of the compensation problem. Evaluation of distributed/centralized and average/instantaneous compensation. -Characteristics, potential and limitations of different types of compensation systems: passive/active, fixed/regulated series/shunt compensations. -General capabilities of voltage source converters for instantaneous 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.
