Total Harmonic Distortion and Effects in Electrical Power Systems

Introduction The power quality of distribution systems has a drastic effect on power regulation and consumption. Johan Lundquist of the Chalmers University of Technology in Goteberg, Sweden put it best, stating “The phrase ‘power quality’ has been widely used during the last decade and includes all aspects of events in the system that deviates from normal operation.” This has been especially tr...

A Practical Approach to Harmonic Compensation in Electrical Power Systems – Using Shunt Active Power Filter

The Shunt active power filters are used in power systems for the compensation of harmonic currents generated for non linear loads. A reference current estimation method for control of SAPF using a digital filter based synchronous reference frame theory is presented. To extract the fundamental component of source current, the synchronous reference frame (SRF) theory is suitable because of its ea...

Optimum PI Controllers of Active Power Filters for Harmonic Voltage Mitigation in Multibus Industrial Power Systems

The bus voltage and branch current detection control strategies of the active power filters used in multibus power systems for harmonic voltage mitigation are analysed in terms of the optimum gains of PI controllers.

A Heuristic Approach to Distributed Generation Source Allocation for Electrical Power Distribution Systems

The recent trends in electrical power distribution system operation and management are aimed at improving system conditions in order to render good service to the customer. The reforms in distribution sector have given major scope for employment of distributed generation (DG) resources which will boost the system performance. This paper proposes a heuristic technique for allocation of distribut...
