Mitigation of Voltage flicker and reduction in THD by using STATCOM

Reduction of Thd in Power Systems Using Statcom

In this paper, an operation methodology of a STATCOM (Static Synchronous Compensator) is proposed for reduction in Total Harmonic Distortion (THD) in power systems. For achieving this objective a comparison is made between two different configurations of Statcom.One is made up of two sets of three-level 12-pulse converter considering magnetic saturation and other is made up of two sets of three...

A Comparison between SVC and STATCOM in Flicker Mitigation of Electric Arc Furnace using Practical Recorded Data

Electric arc furnace (EAF) is one of the largest loads in electric power systems. It is highly time varying and nonlinear. Its reactive power variations cause voltage fluctuations in nearby system which is known as flicker. On the other hand the nonlinear voltage-current characteristic causes strong voltage and current harmonics in EAF. To this end Flexible AC Transmission Systems (FACTS) techn...

Online Tracking and Mitigation of Voltage Flicker Using Neural Network

This paper proposes an on-line neural network based Distributed Static Compensator (DSTATCOM) for a three-phase, three-wire grid connected distribution system to mitigate the voltage flicker. The technique is based on instantaneous tracking of the voltage envelope and phase angle using online neural network based estimator. These estimated values are used by neural controllers to compute inputs...
