摘　　要：从非全相状态下开断相谐振和邻线谐振的基本原理出发,分析了高抗中性点小电抗器限制谐振的数学模型,并计算了典型线路避开谐振的小电抗器数值解,通过理论推导和实际线路的仿真验证,分析了非全相谐振的影响因素,给出了抑制谐振的措施。Based on the principle of the resonance of the non-full phase and the adjacent line, this paper analyzes the resonance inhibiting mathematical model of the small reactor of the neutral point of the HV reactor and calculates the numerical solution of the small reactor corresponding to the typical line in order to avoid the resonance. Through theoretical analysis and ATP simulation of the actual line, several influencing factors of the non-phase are studied with corresponding measures for resonance suppression presented.
