变压器式可控电抗器的新型磁集成结构分析
|
摘要
目前,磁集成变压器式可控电抗器(CRT)存在结构复杂、工艺制作要求高和维护困难等缺点。为此,基于磁集成技术,提出了一种新型磁集成CRT本体结构,即双控制绕组基本单元磁集成CRT;在忽略绕组漏抗与线阻的条件下,建立双控制绕组基本单元磁集成CRT的等效磁路模型与等效电路模型,并据此进行磁通和电流的定量分析及计算式推导;基于场路耦合的有限元分析(FEM),对不同负载时铁芯中的磁场分布和各绕组电流进行仿真,并计算控制绕组容量利用率。算例结果表明,双控制绕组基本单元磁集成CRT在满足高阻抗、弱耦合的基本设计原则的同时,能够实现从空载到满载的平滑过渡,提高了绕组容量利用率,减少了独立基本单元的个数,简化了磁集成CRT的结构。
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.
