In the next few years, more than 80% of AC power is to be processed through power converters owing to their benefits of energy conservation, flexibility, network interconnection, and weight and volume reduction in a number of equipment such as lighting arrestors, HVAC computers, fans, and so on.This paper gives an introduction on power quality (PQ), causes and effects of power quality problems. It also deals with power quality definitions, terminologies, standards, bench-marks, monitoring requirements, financial loss, and analytical quantification. It also discusses various types of nonlinear loads, which cause these power quality problems, they are illustrated, classified, modeled, quantified, and analyzed forassociated power quality issues.

Electric Traction

The traction systems for electric vehicles have advanced considerably over recent years, with the application of different topologies of power converters for the control of various types of electric induction motors and permanent magnet. Furthermore, the evolution of power semiconductor elements of Si to SiC wideband have opened up lines of research and development in this area. The trend of manufacturer’s traction systems is to reach compact systems where the power dissipation is high and the reduction of losses is minimal, for it the implementation of topologies of converters with SiC devices seems to be a good alternative of use to improve the performance of these systems. This paper studies the basic topologies of back to back converter in traction systems als well as the powr quality issues arriving in these systems.

Quality Measurements

Microgrids integrating distributed motor-generator units are commonplace in locomotive and industrial applications. The behavior of these systems is dependent upon various design-operating parameters. However there is a distinct relation between power quality and power flow within these units. This paper presents an analysis of power quality measurements, depicting this interdependence. Respective results can be taken under consideration during power flow programming, enabling enhanced system operation.
