Pumped Storage
★Exhibit Content: Pumped Storage ★Interaction: Mechanical Interaction ★Operation: Pull the handle back and forth to make water flow to the top tank, and observe the power generation phenomenon when the water falls. ★Exhibit Description: Through fun water-pressing interaction, the exhibit helps visitors understand the principle of pumped storage. The main body of the exhibit is a pumped storage device, which mainly consists of a water-pressing structure, water turbine, power meter, water storage tank, and light bulb. The exhibit allows two people to interact simultaneously. Participants drive a piston via the handle to lift water from the bottom to the top. When the water level in the top tank reaches the warning line, the water in the tank flows down, driving the runner inside the acrylic cover. At this time, visitors can see the light bulb in front light up. ★Scientific Principle: Pumped storage power stations can resolve the supply-demand contradiction between peak and off-peak periods of the power grid, and are a way of indirectly storing electrical energy. A pumped storage unit consists of a reversible pump-turbine and a motor-generator set. During the low load period of the power system at midnight, the reversible pump-turbine uses surplus electrical energy from the power system to pump water from the lower reservoir to the upper reservoir, converting electrical energy into potential energy and storing this water in the form of potential energy. When the power system experiences peak load overload, the gates are opened to release the water stored in the upstream reservoir, and the generator set is used to generate electricity, supplementing the power deficit of the generation system during peak periods and meeting the peak-shaving needs of the power system.

★Exhibit Content: Pumped Storage Energy Conversion Demonstration ★Interaction: Electromechanical Interaction ★Operation: Press the handle, and the water pump starts to fill the upper tank with water; when the water level reaches the scale line, the start button lights up; press the button to release the water from the tank, and watch the water drive the turbine to generate electricity and light up the LED beads. ★Exhibit Description: This exhibit consists of an operation console cabinet, water-pressing handle, water pump assembly, upper water storage tank, transparent pipes, visible turbine mechanism, indicator LED beads, water level detection sensor, release button, and a 5mm thick acrylic UV-printed instruction sign. It is a recommended exhibit from the KexMall exhibit mall. Visitors press the handle to drive the water pump, lifting water from the lower part to the top storage tank to complete water storage. When the water level reaches the set scale, a light prompt is triggered. Press the release button, and the high water flows down through the pipes to impact the turbine. The turbine rotates to drive a micro-generator, lighting up the LED beads. The exhibit replicates the complete working process of a pumped storage power station in miniature, intuitively demonstrating the entire energy conversion process of electrical energy-gravitational potential energy-electrical energy, helping visitors understand the practical significance of energy storage and peak shaving. ★Scientific Principle: Pumped storage is an important means of energy storage and peak shaving in the power grid, achieving indirect storage of electrical energy. During low power consumption periods, surplus electrical energy from the grid is used to drive water pumps, pumping water to a high-level reservoir, converting electrical energy into gravitational potential energy of water for storage; when the grid load is tight during peak periods, the high-level stored water is released to impact the turbine, driving the generator to produce electrical energy again and feed it back to the grid, thereby smoothing the supply-demand gap between peak and off-peak periods of the grid and achieving stable dispatch of the power system.
