摘要
通过对铁磁谐发生原理、频率及不同频率下的谐振特性的理论分析,结合220 kV红旗堡变电站66 kV配电网铁磁谐振典型事例,尤其是运行部门操作处理不当,致使事故严重扩大的原因进行分析,对铁磁谐振防范及事故处理具有借鉴意义。
This paper is based on theoretical analysis and research on the occurrence of ferro-resonance principle, frequency range and relevent characteristics, combined with 66kV distribution grid typical ferro-resonance case on the 220kV Red Flag substation, espe-cially with improper manual operation procedure causing widespread accident. It has reference to ferro-resonance prevention and meas-
