摘　　要：《大型汽轮发电机定子端部绕组动态特性的测量和评定》(DL/T 735-2000)标准中对不合格线棒的调频未作具体规定,在标准的实施过程中,频率落入94-115Hz共振范围的线棒处理与否,是根据专业人员的经验判断,主要原因是线棒的调频效果难以保证。针对水轮发电机线棒的具体情况,对调频措施的每个步骤进行分析比较,得出了符合实际要求的调频措施和调频结果,为今后线棒调频工作的开展提供宝贵的经验。Since the standard of Measurement and assessment for the dynamic characteristics of stator＇s end winding for large turbo-generators dose not have detailed stipulations on frequency adjustment for unqualified generator bars, the handling of bars with frequency of 94 - 115 Hz is dependant on people＇s experience. According to the features of the water turbine generator bars, every step of frequency adjustment is analyzed, and the appropriate frequency adjustment measures and effects are obtained.
