摘要：
Magnetic integrated structure controllable reactor of transformer type (CRT) has the disadvantages of complex structure, high process fabrication requirements, and maintenance difficulties. In order to make up for the deficiencies in structural design, based on the magnetic integration technology, we proposed a new-type magnetic integrated CRT named double control winding basic unit magnetic integrated CRT. Ignoring the leakage reactance and resistance of winding, we established an equivalent magnetic circuit model and the equivalent circuit model of double control winding basic unit magnetic integrated CRT. Thereby, we quantitatively analyed the flux and current, thus deriving corresponding calculation formulas. Then, the magnetic field distribution in the core and the winding current at different loads were simulated by the finite element method (FEM) of field-circuit coupling. Finally the control winding capacity utilization was calculated. The results show that, while meeting the basic design principles of high impedance and weak coupling, double control winding basic unit integrated magnetic CRT can realize the smooth adjustment from non-load to full load, improve the capacity utilization rate of winding, reduce the number of independent basic units, and simplify the structure of magnetic integrated CRT. © 2018, High Voltage Engineering Editorial Department of CEPRI.
