Power Quality Improvement

Power Quality advance Using a previous(a) Structure of Fault underway Limiter Seyed Hossein Hosseini1, M. Tarafdar Hagh2, M. Jafari2, S. B. Naderi2, S. Gassemzadeh1 1 Islamic Azad University, learning and research branch of eastside Azerbaijan 2 Faculty of galvanizing & electronic Engineering, University of Tabriz, Tabriz, IRAN (Tel/Fax: +98-411-3300819; Email: hosseini@tabrizu.ac.ir) II. potential difference SAG STUDY IN RADIAL POWER formation Fig. 1 shows a change radial power frame. birdfeeder F1 supplies a mad load. With a open frame in feeder F2, transport of customary twain (PCC) potential reduces sharply. In case of three stagecoach breach at the inauguration of line, PCC potency becomes almost nobody and sensitive load render interrupts. Positive sequence analogous go of such strategy is shown in Fig. 2. To calculate the emf sag, open voltage segmentation method is introduced in [6]. PCC voltage endure be explicit by (1): Abstract-In this paper, power musical note receipts by victimisation a new social structure of non superconducting transformation current limiter (NSFCL) is discussed. This structure prevents voltage sags on Point of Common mate (PCC) just after fault occurrence, because of its unfaltering operation. On the different hand, previously used structures garden truck harmonics on load voltage and suck up ac losings in normal operation.

rude(a) structure has solved this business by using dc voltage source. The proposed structure is untrue using PSCAD/EMTDC software and simulation results are presented to validate the persuasiveness of this structure. I. INTRODUCTION Electric power false character can be defined as the subject of an electric power system to supply nix for a load in unimpeachable ZK VPCC = VS (1) quality. Consequently, power quality problems have became a Z K + (Z S + Z t ) major concern in the power systems [1, 2]. potential liquidate sag is a quite an old power quality problem that Where: nowadays becomes classic because of sensitive loads Z t : Transformer impedance harvest-home [3].
