Abstract
M.Ing.
This study covers the problem of a periodic distortion and it's electronic compensation. The
description and definition of power transfer in a single-phase electrical network is investigated.
The various techniques for achieving optimal power transfer are then derived. From this the
principle of the compensation of reactive power in an electrical power network is derived using
the definition of power transfer.
In order to evaluate and illustrate this principle a system configuration, consisting of a
controlled source of reactive power is used. Due to the complexity of the system it was initially
decided that a computer simulation would serve as an analytical aid. This provides the
opportunity to conduct a thorough investigation into the functioning of the proposed compensator.
Using the knowledge thus gained. an experimental system was developed. The simulated system
is compared to practically obtained results in an experimentally developed compensator in order
to evaluate the accuracy and reliability of the simulation.
The study then concentrates on the characterization of the two systems as applied in the
compensation of reactive power. This analysis also contributes to the identification of
deficiencies in the system.
The study then concludes with a critical evaluation of the work and suggestions for improvement.
This includes the optimization of the total system and the application in industrial power
networks.
