Description
  • The paper deals with the possibilities of utilizing series and shunt active filters compensation in order to mitigate voltage fluctuation and flicker caused by Electrical Arc Furnace (EAF) in industrial distribution systems. A voltage fluctuation that results in flicker is caused by EAF power fluctuation. The Unified Power Quality Conditioner (UPQC) belongs to the group of FACTS devices based on power electronics converters, particularly equipped with component with turn-off capability (e.g. IGBT). They offer many compensation functions for power transmission systems and represent the most progressive way to increase power quality in the systems. The UPQC can be an effective means to suppress voltage fluctuation connected with the function of the EAF. Flicker has been compensated for mainly by using Static Var Compensators (SVC) whose capability to eliminate voltage subharmonics is limited by the frequency up to approximately 10 Hz at maximum. Recently, some studies and tests have been done to prove advantages of active filters (AF) over SVC in this field. The UPQC consists of the parallel and series AF. Therefore it offers more possibilities to solve instantaneous active and reactive power fluctuation than either the parallel or series AF alone. A model of a power system with an electric arc furnace was developed for a typical metallurgical plant. There is an important aspect of the suitability to keep the current SVC compensation. The advanced solution is to add SVC by less dimensioned UPQC for sparing investments and improving the system conditions together. The paper would like to emphasize that FACTS devices should have their position not only in large transmission system but for specific tasks also in local distribution systems.
