چکیده
-This paper proposes a new industry custom power system with a new static var compensator (SVC) main circuit topology, and then introduces the wiring scheme of the new rectifier transformer, the harmonic suppression mechanism of the inductive filtering different from the traditional passive filtering (PF) and the active filtering (AF), and the dynamic reactive compensation at the third side of the new rectifier transformer. Based on this, the operation mechanism of the inductive filtering and the reactive compensation that the new SVC has are theoretically analyzed in detail. The simulation results verify the correctness of the theoretical analysis mentioned above, and expressed the good effects of the unique inductive filtering and the reactive compensation that the new SVC has.

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...

متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
