Simulation and Analysis of Electromagnetic Transient Characteristics of Controllable Reactor of Transformer Type
Authors: , , ,
Abstract: This paper analyzed the winding construction of Controllable Reactor of Transformer Type (CRT), based on the duality theory a new transient model of CRT is proposed. It can reflect the electric circuit coupled with magnetic circuit correctly. Fitting the magnetization curve with the function fitting method and the simulation results prove the accuracy of the model. Proposing divide CRT’s working process into operating process and grade-changing process. And analyze and research the transient processes of the two processes respectively. According to the transient model build CRT no-load switching-in mathematical model, do simulation research with ATP-EMTP, analyze the phenomena of magnetizing inrush current in operating process. And analyze current of each winding in grade-changing process, the simulation results verify the correctness of the model and analyze the transient characteristic of CRT.
