在电路建模方面,集成滤波电感变压器缺少能完善其表达电量特性的器件,且其建模方式复杂、计算步骤和计算时间冗长。为此,提出了一种利用电感矩阵作为中间桥梁的新型磁场-电路耦合法。首先分析了集成滤波电感变压器的绕组结构;然后以求解数学模型的方式,分析了新型磁场-电路耦合法的实际数学计算过程,并列写多种工况下的变压器端口条件;最后以容量为300 k VA的舰船用集成滤波电感整流变压器及滤波系统为例,开展了仿真研究。通过对实际系统的运行测试发现,所有参数的仿真误差均在7.5%以内,所提出的方法能准确地模拟集成滤波电感变压器的实际运行状态,且耗时短、计算精度高。结果表明基于新型磁场-电路耦合法的集成滤波电感变压器及滤波系统仿真建模方法具有良好的工程应用与推广价值。

英文摘要：

In the modeling of integrated filter inductance transformer, there is few device that can express the features of the transformer, and it is hard to build the complex model. Besides, the calculating steps are too many and the total calcu- lating time is quite long. To solve the above problems, we propose a new field-circuit coupling method by using the inductance matrix to connect the magnetic field. First, the winding construction of integrated filter inductance transformer is analyzed, then actual mathematical calculation processes of the new field-circuit coupling method are analyzed by solving the mathematical model, and a variety of port conditions under different working conditions are presented. Based on a 300 kVA integrated rectifier transformer and filter inductor used for ship system, the simulation research is carried out. By testing the operation on the actual system, the results show that the simulation errors of all parameters are within 7.5%, the method can accurately simulate the actual operation state of the transformer, and it takes shorter time and has high accuracy. The proposed method of the integrated filtering inductance windings transformer and the filtering system based on the new field-circuit coupling has good application and popularization values.
