消谐装置在500kV东坡站的应用

摘要

The application of resonance-eliminator in 500kV Dongpo substation is researched in this paper.The FR's harm and installing resonance-eliminator in 500kV Dongpo substation's necessity is pointed out.The advantage and disadvantage of eliminate resonance measures are also analyzed.In neutral grounded system,not only has zero sequence resonant,but also has positive and negative sequence resonant,then a FR's eliminate measure is proposed.The resonance eliminator's operating principle is analyized and maintenance announcement is pointed out.%研究了消谐装置在500kV东坡站的应用.指出了铁磁谐振的危害和东坡站安装消谐装置的必要性,分析了各种消谐措施的优缺点.在中性点直接接地系统中,不仅存在零序谐振,还存在正序/负序谐振,进而提出了适合东坡站的消谐措施,分析了消谐装置的工作原理,并指出了维护注意事项.
