Simulation Analysis for Controllable Reactor of Transformer Type with Multifold Magnetic Materials Integration

This paper presents a construction of a controllable reactor of transformer type (CRT) with multifold magnetic materials, and the construction based on the magnetic-integration techniques is used to weaken the magnetic coupling effect among control windings and eliminate requirement of series current limiting reactance. At last, based on the proposed equivalent circuit of integrated magnetic structure, a simulation model is fabricated by MATLAB/SIMULINK. Simulation analysis of winding current and control characteristic show that this construction meets the design requirements of “high impedance and weak coupling”, the harmonic content of the work winding is small, also the construction can realize the smooth reactive power regulation and react with a high speed. The validity of the construction and the correctness of the simulation model are proved by the results of simulation. This multifold magnetic materials integration method offers a reference to the integration of complex electromagnetic equipment.
