Influence and analysis of power grid fluctuation on the operation of shanghai synchrotron radiation facility

  • 摘要: 电网波动对上海光源加速器的正常运行有较大影响。针对该问题,展开了系统的分析和研究工作。首先介绍了电网波动的成因以及电网波动对上海光源的影响情况。通过对具体事例进行分析,优化了上海光源加速器受电网波动影响后的基本恢复流程。分析了各硬件系统在发生电网波动时的不同表现,并依此探讨了如何优化此类故障的处理流程,建立完善的机器恢复程序。针对外电网波动提出若干建议,并提出了面对电网波动时需要采取的措施,尽可能降低电网波动对如低温压缩机、超导高频腔等关键设备的影响。以期缩短实际故障时间,加快机器恢复速度,保障上海光源稳定运行。以近10年运行数据为基础,研究发现电网波动对上海光源的影响存在若干重要阈值,这些阈值对机器恢复具有指标性作用。对因电压暂降产生的二次故障进行分析讨论,并提出若干建议。
