The invention discloses an electric energy quality control analysis system of a low-voltage power grid, and belongs to the technical field of power generation and supply. The damage of a pipeline water hammer effect of a pumped storage power station can be reduced. The system comprises the pumped storage power station, the pumped storage power station comprises a controller, a reservoir, a water turbine and a pipeline, wherein the two ends of the pipeline are in butt joint connection with a water outlet of the reservoir and a water inlet of the water turbine correspondingly, and the pipeline can guide water of the reservoir to the water turbine. A plurality of side holes are formed in the pipeline along the pipeline, and the side holes are arranged at different heights of the pipeline. Each side hole is provided with a pressure regulating device. Each pressure regulating device comprises a connecting pipe and a pressure regulating cavity, wherein the pressure regulating cavity is vertically arranged, the side
