摘要：
Modeling method and transition time calculation are two important issues in the research of magnetically-saturated controllable reactor. According to the saturation characteristics of magnetically-saturated controllable reactor and by analyzing the small slope magnetization characteristic curve, the quantitative relationship among its rated capacity, rated voltage, turns ratio and winding resistance is obtained and the way for setting the parameters of simulation model based on MATLAB is presented. The small slope magnetization characteristic curve is piecewise linearized to divide the transition from no-load to full-load into two processes: the DC flux increases linearly with time and the control current varies according to the charge law of a linear RL circuit, based on which, a more accurate formula of transition time calculation is derived. Case simulation confirms the effectiveness of the presented analysis method.
