Design and Simulation of 11/0.4 kV Distribution Transformer Using ANSYS

Abstract

This work presents a Finite Element Method (FEM) modeling of a 3-phase, 11/0.4 kV, 50 Hz, oil immersed, core (stack) type distribution transformer. In this work The ANSYS package is used to build the finite element model of the transformer, using actual transformer parameters. To investigate transformer performance several analyses are accomplished on this model such as; static analysis, transient analysis, harmonic analysis. Two types of analysis are considered; the linear analysis (using constant permeability) and the nonlinear analysis using the B-H curve of iron. The results are presented in 2D vector and contour colored plots of the FE model, the voltage and current curves, the magnetic flux lines, flux density, field intensity, current density, and magnetic forces. ‫ﺣﺎﺳﻮﺑﻲ‬ ‫ﻧﻤﻮذج‬ ‫وﻋﻤﻞ‬ ‫ﺗﺼﻤﯿﻢ‬ ‫ﻟ‬ ‫ﺗﻮزﯾﻊ‬ ‫ﻤﺤﻮﻟﺔ‬ 11 \ 0.4 ‫ﺑ‬ ‫ﻓﻮﻟﺖ‬ ‫ﻛﯿﻠﻮ‬ ‫ﺎ‬ ‫ﺳﺘﺨﺪام‬ ‫ﺑﺮﻧﺎﻣﺞ‬ ANSYS ‫ا‬ ‫ﻟﺨﻼﺻﺔ‬ ‫ﺪدة‬ ‫اﻟﻤﺤ‬ ‫ﺮ‬ ‫اﻟﻌﻨﺎﺻ‬ ‫ﺑﻄﺮﯾﻘﺔ‬ ‫ﻧﻤﺬﺟﺔ‬ ‫ﯾﻘﺪم‬ ‫اﻟﻌﻤﻞ‬ ‫ھﺬا‬ FEM ‫ﻮر‬ ‫اﻟﻄ‬ ‫ﺔ‬ ‫ﺛﻼﺛﯿ‬ ‫ﻊ‬ ‫ﺗﻮزﯾ‬ ‫ﺔ‬ ‫ﻟﻤﺤﻮﻟ‬ , 11 \ 0.4 ‫ﺖ‬ ‫ﻛﯿﻠﻮﻓﻮﻟ‬ , 50 ‫ﺰ‬ ‫ھﺮﺗ‬ , ‫ﺐ‬ ‫اﻟﻠ‬ ‫ﻮع‬ ‫ﻧ‬ ‫ﻦ‬ ‫ﻣ‬ ‫ﺖ‬ ‫ﺑﺎﻟﺰﯾ‬ ‫ﺔ‬ ‫ﻣﻐﻄﺴ‬. ‫ﺎت‬ ‫اﻟﺒﺮﻣﺠﯿ‬ ‫ﺔ‬ ‫ﺣﻘﯿﺒ‬ ‫ﺘﺨﺪﻣﺖ‬ ‫اﺳ‬ ‫ﻞ‬ ‫اﻟﻌﻤ‬ ‫ﺬا‬ ‫ھ‬ ‫ﻲ‬ ‫ﻓ‬ ANSYS ‫ﻟﻠﻤﺤﻮﻟﺔ‬ ‫اﻟﻤﺤﺪدة‬ ‫اﻟﻌﻨﺎﺻﺮ‬ ‫ﻧﻤﻮذج‬ ‫ﻟﺒﻨﺎء‬ , ‫ﻓﻌﻠﯿﺔ‬ ‫ﻟﻤﺤﻮﻟﺔ‬ ‫ﻣﺘﻐﯿﺮات‬ ‫ﺑﺄﺳﺘﺨﺪام‬. ‫ﻦ‬ ‫ﻣ‬ ‫ﻖ‬ ‫ﻟﻠﺘﺤﻘ‬ ‫أداء‬ ‫اﻟﻤﺴﺘﻘﺮة‬ ‫اﻟﺤﺎﻟﺔ‬ ‫ﺗﺤﻠﯿﻞ‬ ‫ﻣﺜﻞ‬ ‫اﻟﻤﻮدﯾﻞ‬ ‫ھﺬا‬ ‫ﻋﻠﻰ‬ ‫ﺗﺤﻠﯿﻼت‬ ‫ﻋﺪة‬ ‫اﺟﺮاء‬ ‫ﺗﻢ‬ ‫اﻟﻤﺤﻮﻟﺔ‬ , ‫اﻟﻌﺎﺑﺮة‬ ‫اﻟﺤﺎﻟﺔ‬ , ‫اﻟﺤﺎﻟﺔ‬ ‫و‬ ‫ﺔ‬ ‫اﻟﺘﻮاﻓﻘﯿ‬. ‫ﻲ‬ ‫اﻟﺨﻄ‬ ‫ﻞ‬ ‫اﻟﺘﺤﻠﯿ‬ ‫ﺎ‬ ‫وھﻤ‬ ‫ﻞ‬ ‫اﻟﺘﺤﻠﯿ‬ ‫ﻦ‬ ‫ﻣ‬ ‫ﻮﻋﯿﻦ‬ ‫ﻧ‬ ‫ﺎد‬ ‫اﻋﺘﻤ‬ ‫ﻢ‬ ‫ﺗ‬) ‫ﺔ‬ ‫ﺛﺎﺑﺘ‬ ‫ﻤﺎﺣﯿﺔ‬ ‫ﺳ‬ ‫ﺘﺨﺪام‬ ‫ﺑﺎﺳ‬ (‫ﻞ‬ ‫اﻟﺘﺤﻠﯿ‬ ‫و‬ ‫ﻣﻨﺤﻨﻰ‬ ‫ﺑﺄﺳﺘﺨﺪام‬ ‫اﻟﻼﺧﻄﻲ‬ B-H ‫ﻟﻠﺤﺪﯾﺪ‬. ‫ﺛﻨﺎ‬ ‫ﻮم‬ ‫رﺳ‬ ‫ﻲ‬ ‫ﻓ‬ ‫ﮭﺎ‬ ‫ﻋﺮﺿ‬ ‫ﻢ‬ ‫ﺗ‬ ‫ﺎﺋﺞ‬ ‫اﻟﻨﺘ‬ ‫ﻮذج‬ ‫ﻟﻨﻤ‬ ‫ﺔ‬ ‫ﻣﻠﻮﻧ‬ ‫ﺎد‬ ‫اﻻﺑﻌ‬ ‫ﺔ‬ ‫ﺋﯿ‬ ‫اﻟﻤﺤﺪدة‬ ‫اﻟﻌﻨﺎﺻﺮ‬ , ‫ﺎر‬ ‫واﻟﺘﯿ‬ ‫اﻟﺠﮭﺪ‬ ‫ﻣﻨﺤﻨﯿﺎت‬ , ‫ﻲ‬ ‫اﻟﻤﻐﻨﺎطﯿﺴ‬ ‫ﯿﺾ‬ ‫اﻟﻔ‬ ‫ﻮط‬ ‫ﺧﻄ‬ , ‫ﯿﺾ‬ ‫اﻟﻔ‬ ‫ﺔ‬ ‫ﻛﺜﺎﻓ‬ , ‫ﺎل‬ ‫اﻟﻤﺠ‬ ‫ﺪة‬ ‫ﺷ‬ ‫اﻟﻤﻐﻨﺎطﯿﺴﻲ‬ , ‫اﻟﺘﯿﺎر‬ ‫ﻛﺜﺎﻓﺔ‬ , ‫اﻟﻤﻐﻨﺎطﯿﺴﯿﺔ‬ ‫اﻟﻘﻮى‬ ‫و‬ .
