Current nonlinear models of transformers (the EMTP model for example) are inadequate to accurately predict the effects of physical phenomena such as ferroresonance, inrush currents, saturation due to geomagnetically- induced currents, and transformer deration due to power quality problems. Better modeling of complex flux - current relationships is needed. Techniques from nonlinear dynamics and the newly emerging field of chaotic systems are proposed to validate the improved models and gain more insight into the observed phenomena.

当前的变压器非线性模型（例如 EMTP 模型）不足以准确预测铁磁谐振、浪涌电流、地磁感应电流引起的饱和以及电能质量问题引起的变压器降额等物理现象的影响。 需要对复杂的通量-电流关系进行更好的建模。 提出了非线性动力学和新兴混沌系统领域的技术来验证改进的模型并更深入地了解观察到的现象。
