New power systems mainly using new energy are becoming an important choice for sustainable development of energy. The energy storage system can be used for transient electric energy quality management, and through rapid adjustment and compensation of voltage and power of the electric power system, regional oscillation caused by abrupt load change and interconnection of a power grid is eliminated, and transient stability of the power grid is improved. Meanwhile, the high-capacity energy storage system with quick response can be used as an energy buffer to decouple power generation and power utilization in time and space, so that the power utilization self-regulating capacity of a regional power grid can be enhanced, the power transmission and transformation capacity can be improved, and the contradiction between regional supply and demand can be solved.

The novel high-voltage direct-current direct-hanging energy storage technology integrates a voltage source type converter (voltage source converter, VSC), a converter valve and a direct-current energy storage valve, and has the advantages of high modularization degree, low system network loss, good economic benefit, high operation reliability and the like. By integrating the direct current energy storage valve on the direct current side of the VSC converter valve, alternating current-direct current power conversion and energy storage are realized at the same time. Compared with the traditional energy storage technology, the novel high-voltage direct-current direct-hanging energy storage system is higher in voltage level and larger in capacity, has stronger power grid adjustment capability and power grid supporting function, and has important research significance on novel power systems taking new energy as a main body.

At present, the energy storage valve tower frames of the high-voltage direct-hanging energy storage valves are designed by referring to the valve tower of the conventional flexible direct-current converter valve to a certain extent, and the valve tower structures of the high-voltage direct-hanging energy storage valves are fresh.

The high-voltage direct-current direct-hanging energy storage system has the advantages that the number of battery cells required by each phase is huge, and the battery cells are integrated in a plurality of energy storage electric cabinets in series-parallel connection, so that the number of the energy storage electric cabinets is large, and the size of each energy storage electric cabinet is large. At present, a valve tower of a conventional flexible direct current converter valve mostly adopts a multi-layer plate-shaped supporting frame structure, adjacent plate-shaped supporting frames are supported by insulators with limited length sizes, and therefore the interlayer distance of the supporting frames is small, and a large-size energy storage electric cabinet is difficult to accommodate. In addition, the number of the energy storage electric cabinets in the high-voltage direct-current direct-hanging energy storage system is increased, so that the design of the valve tower structure has higher requirements on bearing strength.

Further, in the valve tower structure of the conventional flexible direct current converter valve, the width of the supporting frame is very wide, which can reach several meters, but the interlayer distance of the frame is limited, so that the installation space in the middle of the frame is very small, and the insulator is difficult to install. In some current technical solutions, the installation of the insulator in the middle of the frame is eliminated. However, the weight of a single energy storage electric cabinet is very large and can reach 2 tons to 3 tons, if the middle part of the frame is not supported by an insulator, the stress concentration of the frame structure can be caused, and further, the bearing strength of the middle position of the frame is insufficient, so that the frame is easy to damage. Although the frame can be reinforced by adding reinforcing members, this approach tends to add significant weight to the valve tower.

Based on the above consideration, the application provides a valve tower structure suitable for a high-pressure direct-hanging energy storage valve, which comprises a multi-layer frame. The energy storage valve tower frame that this application formed through providing the multilayer frame improves the ability that energy storage valve tower frame held energy storage electricity cabinet under the unit area. This application is through regard as the frame with the space frame that holds the chamber, avoids adopting the insulator to support the mode that forms the frame among the prior art, improves the accommodation space of frame to do benefit to and hold the energy storage electric cabinet of jumbo size.
