In order to obtain DC bias characteristics of controlled shunt reactors (CSRs) of thyristor controlled transformer (TCT) type in the thyristor abnormal operation state, a DC bias characteristics analysis model for the CSR based on Jiles-Atherton(J-A) theory is proposed. A single-phase prototype for the CSR is developed and tested. The coil currents and magnetic flux densities of the iron core are calculated in time domain and frequency domain based on the model. The experimental results agree well with the calculated results. The DC bias characteristics of the CSR are analyzed.

TCT型晶闸管非正常工作状态下CSR直流偏压特性分析


为了获得晶闸管控制变压器(TCT)型可控并联电抗器(CSR)在晶闸管异常运行状态下的直流偏置特性，提出了一种基于Jiles-Atherton(JA)理论的CSR直流偏置特性分析模型。开发并测试了 CSR 的单相原型。基于该模型，在时域和频域上计算了铁芯的线圈电流和磁通密度。实验结果与计算结果吻合较好。分析了CSR的直流偏置特性。
