摘　　要：广东省韩江高陂水利枢纽龙湖水电站水轮发电机组在发电机模拟并网过程中发生故障,针对故障发生的过程,结合现场作业条件,对铁磁谐振原理进行了理论定量分析,并根据H.A.Peterson谐振分布原理,得出了故障原因,提出了对应的消谐措施,分析成果可为应对铁磁谐振事故提供借鉴。The hydro-generator unit of Longhu Hydropower Station of Hanjiang Gaopi Water Control Project in Guangdong has a fault in the process of generator simulation and grid connection.Combined with the on-site operating conditions,a theoretical quantitative analysis of the ferromagnetic resonance principle is carried out.According to the H.A.Peterson resonance distribution principle,the cause of the fault is obtained and the corresponding measures are proposed.The results can provide reference for dealing with ferroresonance.
