摘要
Abstract
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.关键词
