摘要 通过对影响串联补偿线路发生铁磁谐振的因素的分析,选取激发铁磁谐振产生的主要故障类型和影响因素作为评价对象,构建评价指标体系。以铁磁谐振的影响因素建立判断矩阵,计算各影响因子的权重,并结合线路防振措施提出防护系数的概念,确立评价模型进行综合分析,计算线路铁磁谐振发生的概率,从而实现串联补偿线路铁磁谐振的风险评估。最后,通过案例分析验证了方法的正确性和可行性,可以更准确、可靠地对串联补偿线路发生铁磁谐振的风险进行评估。方法对串补线路铁磁谐振的抑制措施选定具有重要的指导意义,有效避免铁磁谐振的发生。 The factors of affecting ferromagnetic resonance occurred in series compensation line of distribution network were analyzed.The main failure types and influence factors generated by ferromagnetic resonance were selected as the evaluation objects to construct the system of evaluation index.The influence factors of ferromagnetic resonance were used to construct the judgement matrix and calculate the weight of each influence factor.And the conception of protection coefficient was proposed combining with the anti-vibration measures of the line.Then the evaluation models were established for comprehensively analyzing and calculating the probability of occurrence of line ferromagnetic resonance.Thereby the risk assessment of the ferromagnetic resonance was achieved in the series compensation line.It is testified by an instance that the method is correct and feasible.The selection of the suppression measures for ferromagnetic resonance of the series-compensated line has important guiding significance and it can effectively avoid the occurrence of ferromagnetic resonance.
