基于ANASYS的磁控电抗器场路耦合模型研究 Research of Magnetically Controlled Reactor Field-Circuit Coupled Model Based on ANASYS

本文对380 V/13A磁控电抗器样机耦合物理场进行了理论分析。基于有限元分析理论，在ANSYS中建立了精确的样机2-D场路耦合模型。该场路耦合模型将电磁场方程和电磁装置所满足的电路方程直接耦合起来，反映了磁控电抗器实际的电磁瞬态过程。根据建立的2-D场路耦合模型，对小截面的磁场强度与磁感应强度进行了计算，仿真结果与理论分析基本相符，验证了磁路耦合仿真方法的正确性。本文所建立的380 V/13AMCR样机2-D场路耦合模型，对电抗器的设计及性能分析有重要的指导作用。 The physical coupled field of the 380 V/13Aexperimental prototype is systematically analyzed in this paper. A precise 2-D field-circuit coupled model is established in ANASYS platform which is based on finite element theory. Both magnetic circuit equations and electric circuit equations obeying specific circuit configuration are included in this field-circuit coupled model upon which it explicates the real electromagnetic transient process; and upon which an accurate computation of electromagnetic field intensity and electric magnetic induction intensity is given. Simulation results coincide with that of the basic principle’s derivation through which the correctness of the field-circuit coupled model is substantiated. The 2-D field-circuit coupled model of 380 V/13AMCR prototype presented here is a solid foundation for reactor design and its performance analysis.
