摘要
针对直流偏磁影响下换流变压器的运行状况,通过有限元数值模拟分析了铁心磁通密度的变化规律。基于硅钢片中损耗与磁密的拟合关系,利用半波平均算法求解了不同偏磁情况下产品的空载损耗。
Aiming at operational condition of converter transformer under DC bias, the rules of core magnetic flux density are analyzed by numerical simulation of finite element method. Based on fitting relation of magnetic flux density and loss inside the silicon steel sheet, the no-load loss of product is solved with different DC bias conditions in accordance with half-wave average algorithm.
