Abstract

The invention relates to an upper liquid accumulation system for a liquid gravitational potential energy storage power station. The upper liquid accumulation system comprises liquid accumulation containers, a pipeline, a valve, a monitoring control device, an anti-freezing and deicing facility and a mountain body, wherein the upper liquid accumulation system is positioned on the mountain body; each liquid accumulation container is a closed or semi-closed tank body located on a foundation; when the ground is bumpy, each liquid accumulation container can adopt a closed or semi-closed tank body structure which is supported by a support so as to be suspended on the ground; a liquid level monitoring device is arranged on each container; the containers are connected through the pipeline; the valve is arranged on the pipeline; the monitoring control device controls inflow and outflow of liquid and liquid level in each container by controlling opening and closing of each valve; the upper liquid accumulation system is provided with the anti-freezing and deicing facility; during a power load valley period, the liquid in a lower liquid accumulation device is lifted to the liquid accumulation container, and energy is stored; and during a power load peak period, the liquid orderly flows out of each liquid accumulation container through the pipeline under the coordination of the monitoring control device, a power generation device is driven, and the gravitational potential energy of the liquid is converted into kinetic energy. The upper liquid accumulation system is large in energy storage scale and low in requirements on terrain and geology conditions.

Description

technical field [0001] The invention relates to an upper liquid storage system of a liquid gravitational potential energy storage power station, which belongs to the field of energy storage power stations. technical background [0002] Definition of Terms - Zero Potential Energy Plane: In the expression E=mgh of gravitational potential energy, since the height h is relative, the numerical value of the gravitational potential energy is also relative. An object has gravitational potential energy mgh, which is relative to a certain horizontal plane, that is, the height of this horizontal plane is taken as zero. When the object is located on this reference plane, the gravitational potential energy is zero, so it is called the zero potential energy plane. [0003] With the development of my country's industrialization level and the increase of people's daily electricity consumption, the peak-to-valley difference of power grid electricity load is getting larger and larger, and wit...
