Figure 7.

A bar chart compares relative simulation times for current transformers C0, C2, and C3 using the Jiles-Atherton model and the proposed model, with error bars representing standard deviation.

The image presents a bar chart with relative simulation time on the vertical axis and current transformer types C0, C2, and C3 on the horizontal axis. Two bars are shown for each transformer: one represents the Jiles-Atherton model and the other represents the proposed model. The Jiles-Atherton model shows higher relative simulation times for all three transformer types, reaching nearly 30 for C0, about 24 for C2, and around 22 for C3. The proposed model shows substantially lower times, approximately 10 for C0, 9 for C2, and 6 for C3. Error bars indicate the standard deviation for each value, with the proposed model showing slightly larger variability for C0 and C2 compared to C3.

Comparison of the relative simulation time $T_{r}$ between the Jiles–Atherton model and the control-oriented model

Note(s): The ODE15s variable step-size solver with a maximum step-size of $10^{- 6}$ s is selected. For all representative CTs (⁠ $C_{0} C_{2}$ and $C_{3}$ ⁠), the computation time of the control-oriented model is significantly smaller
