紧凑型三相立体式磁控配电变压器研究
Research on Compact Three-phase Three-dimensional Magnetically Controlled Distribution Transformer
摘要
Abstract
In view of such issues as large voltage fluctuations at the end of long transmission lines and the difficulty of urban power grid expansion,a compact three-phase three dimensional maganetically controlled distribution trans-former that combines a controllable reactor with a distribution transformer is proposed.Its working process and ad-vantages are analyzed through theoretical derivation and finite element simulation.The iron core of this compact magnetically controlled distribution transformer consists of three identical single frames,with each phase winding wound on two single frames.Each single frame iron core has a magnetic valve with a smaller cross-sectional area at the upper and lower transverse yokes,and each small cross-sectional iron choke with an air gap is wound with a DC excitation winding.Both theoretical analysis and finite element simulation results show that the compact magnetical-ly controlled distribution transformer,on the condition of maintaining footprint of original power distribution trans-former,can not only output reactive power and improve the reactive power and voltage control ability,but also trans-form voltage and transfer electric energy normally without distortion and imbalance of voltage and current wave-forms,which is suitable for urban distribution stations with high proportion of new energy access,high cable utiliza-tion rate with limited space.关键词
