摘要
在分析双绕组变压器的差动保护算法的基础上，提出了适用于三相三绕组变压器的比率制动式算法，并对判据进行了简化。同时利用二次谐波制动防止变压器在励磁涌流情况下误跳闸。
Based on the analysis of the differential protection of the double winding transformer,the paper presents a simplified ratio restraint algorithms for the three phase,three winding transformer.The second harmonic restraint principle is adopted to prevent the false tripping during magnetizing in rushcurrent.
