Controllable reactor is the common equipment in the modern power system, which plays an important role in voltage control and reactive power compensation. The core structure of reactor effects the magnetic field distribution in the core and the loss of reactor. In this paper, the models of two kinds of classic reactors are built by the ANSYS command flow method, and explain the differences between magnetic valve controllable reactor and common reactor. This paper points out the advantages of command flow compared with the graphical user interface and the important role of ANSYS finite element analysis in the structural design of reactor.

Simulated Analysis

Aiming at the condition that the exciting power is bigger when the orthogonal magnetizing controllable reactor adjusts the flux in wide range and there is coupling between the alternate current(AC) magnetic circuit and the direct current (DC) circuit. This paper proposed a kind of orthogonal magnetizing controllable reactor based on DC memory flux. The aluminum nickel cobalt alloy (AlNiCo) magnet with low coercive force and high residual flux density was used so that the DC flux could be online tuned without additional copper loss. This paper designed the new type of orthogonality magnetic structure without coupling between the AC-DC circuit and magnetic circuit. The simulated analysis result shows that this electric reactor realizes the unidirectional control from the DC magnetic circuit to AC magnetic circuit, which makes the inductor of electric reactor controllable more easily.

Ferromagnetic Steel

We investigated effects of contact gap on magnetic nondestructive evaluation technique using a magnetic single-yoke probe. Firstly, we evaluated hysteresis curves and impedance related to permeability of the material measured by a single-yoke probe, when an air gap length between the probe and specimens changes. The hysteresis curve gradually inclines to the axis of the magneto-motive force and magneto-motive force at which the magnetic flux is 0 decreases with increasing the gap length. The effective permeability also decreases with increasing the gap thickness. The incremental of gap thickness increases the reluctance inside the magnetic circuit composed of the yoke, specimen and gap, which results in the reduction of flux applying to specimen.

The Relationship

This paper proposes a computation method using the equivalent magnetic circuit to analyze the driving force for the non-contact permanent magnet linear drive system. In this device, the magnetic driving force is related to the rotation angle of driving wheels. The relationship is verified by finite element analysis and measuring experiments. The result of finite element simulation is in good agreement with the model established by the equivalent magnetic circuit. Then experiments of displacement control are carried out to test the dynamic characteristic of this system. The controller of the system adopts the combination control of displacement and angle. The results indicate that the system has good performance in steady-state error and response speed, while the maximum overshoot needs to be reduced.
