Problems solved by technology

The above situation leads to a long time required to complete a nonlinear transient magnetic field analysis of the 3D model of the core reactor. In the case of large-scale data, relying only on manual operation and using the traditional GUI interface simulation method, it is inevitable that there will be Cause waste of human resources and increase the risk of errors in simulation

Description

technical field [0001] The embodiments of the present invention relate to the technical field of reactor design, in particular to a method for batch simulation of core reactors. Background technique [0002] Reactor is an important electrical equipment in the power system, which plays the role of suppressing harmonics, reactive power compensation, and limiting short-circuit current in the system. Compared with air-core reactors, iron-core reactors have the advantages of small footprint, low cost, good electromagnetic compatibility, and large inductance, and are widely used in occasions that require large-capacity reactive power compensation. To ensure the system's demand for large inductance, the iron core material of the iron core reactor is made of silicon steel sheet, its magnetic permeability has nonlinear characteristics, and there is a phenomenon of hysteresis saturation. It is necessary to set an air gap between the iron core cakes to improve the inductance. linearit...
