| 摘 要： | 磁阀式可控电抗器(Magnetic-valve controllable reactor, MCR)具有直流偏磁、绕组电流谐波大和磁路中磁通密度不同的特点,这些特点不仅导致其损耗计算方法与电力变压器不同,而且使准确计算MCR的铁芯和绕组损耗比较困难。本文将铁芯分区与J-A动态逆模型相结合,提出MCR铁芯损耗的计算方法;考虑漏磁和谐波的影响,分析推导得到MCR的绕组损耗系数的计算方法和表达式。最后,通过实例的仿真和实验,验证了提出的铁芯损耗计算方法和绕组损耗系数的正确可靠性。

| Abstract: | Magnetic-valve controllable reactor(MCR)has characteristics of DC bias and different types of magnetic flux density in the magnetic circuit and winding current distortion.These characteristics not only lead to loss calculation method of MCR different from that of power transformer,but also make it more difficult to calculate the core loss and wingding loss of MCR accurately.Our study combines core partition method with dynamic inverse J-A model to calculate the core loss of MCR.The winding loss coefficient of MCR is proposed,which takes into account the influence of harmonics and magnetic flux leakage on the winding loss of MCR.The result shows that the proposed core loss calculation method and winding loss coefficient are effective and correct for the loss calculation of MCR. |
