The study first introduces the causes of power grid fluctuation and its impact on SSRF in order to solve this problem. Through the analysis of former cases, the basic recovery process of SSRF accelerator affected by power grid fluctuation is sorted out and optimized. This paper also analyzes the different performance of each hardware system in the face of the power grid fluctuation. In addition, it discusses how to optimize the processing flow and establish a perfect machine recovery program. Several suggestions and measures are put forward in response to the fluctuation of the external power grid, so as to minimize the impact of the power grid fluctuation on key equipment such as cryogenic compressor and superconducting radio-frequency cavity, shorten the actual failure time, speed up the machine recovery, and ensure the stable operation of SSRF. Based on the operation data in the past ten years, it is found that there are several important thresholds for the impact of power grid fluctuations on SSRF, and these thresholds have an indicator effect on machine recovery. The secondary faults that are caused by voltage sags are analyzed and discussed in this paper, and some guidance and suggestions are put forward.
