Abstract:

The electric power theory is of fundamental importance in most aspects of electric power engineering, enabling to analyze and control the grid based on an unambiguous physical interpretation of the power and current flow. The futuristic SmartGrid concept will include scenarios of potentially very challenging network conditions, due to large impact of non-linear loads, combined with unsymmetric and non-sinusoidal voltage regimes. New and more advanced power theories are needed, in order to maintain correct physical understanding of the power grid, independently of voltage conditions. Moreover s

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: The use of power electronic converters provides a more efficient, accurate and dynamic solution to reactive compensation. In this thesis the application of power electronic converters to shunt reactive compensation will be discussed. In particular voltage dips and voltage unbalance are considered as both can be mitigated by means of shunt reactive compensation. A pre-existing uninterruptible power supply is adapted to operate as a shunt reactive compensator. The uninterruptible

Abstract:

It is specifically important to focus on voltage stability analysis of the power system to avoid worst case scenarios such as voltage collapse. The purpose of this thesis is to identify methods for enhancing the steady-state voltage stability using FACTS devices and determining their impact on real and reactive power losses, improvement of bus voltage magnitude, and transmission line loadability. To achieve this, FACTS devices such as Static VAR Compensator (SVC), Static Synchronous Compensator (STATCOM), and Thyristor Controlled Series Capacitor (TCSC) are used in the test system as three sep

Electrical Power distribution systems suffer from power quality (PQ) problems such as poor power factor, load unbalancing, harmonics, distortion in voltage etc. The contribution of non linear loads incorporating power electronics devices viz. switch mode power supply, variable frequency drive (VFD), lighting loads (CFL, LED) etc. in power distribution systems is high. This leads to higher PQ problems into the system such as harmonics injection in voltage and current, high neutral current etc. Since the continued presence of PQ problems deteriorates the quality of power at the end u

Not only do harmonics increase the extra losses in the transmission process, but they also pollute the source side of distribution system which would make the original three-phase sinewaves voltage become three-phase imbalance or generate harmonic distortion. One of the solutions to harmonics is the use of active power filter (APF) for nonlinear loads.

Abstract:

The management of parallel and series resonance conditions is important for ensuring that harmonic levels are managed on utility networks, and that shunt compensators are able to operate without constraints for various network conditions (states). For these and similar problems, harmonic impedance assessment of the ac network is required for the design of ac filter or shunt capacitor bank installations. This is particularly important for large installations connected to HV or EHV systems, because resonances at these voltage levels tend to be highly un-damped resulting in potentially damaging v
