Liquid-cooled string energy storage converter and booster integrated cabin launched

With the global emphasis on green energy and sustainable development, new energy construction has gradually become an important means to promote economic growth and environmental protection. In this context, energy storage systems, as key technologies in new energy construction, have received widespread attention. As an important component of the system, the energy storage converter and booster integrated cabin integrates the two major functions of converter and boost, realizes efficient storage, conversion and utilization of energy, and is of great significance to the achievement of dual carbon goals.

Aiming at new energy distribution storage, regional energy storage, and shared energy storage power stations, we have launched a liquid-cooled string energy storage converter and booster integrated cabin. The single cabin capacity of this product can reach 5MW and 6MW. Through the flexible module string method, it can achieve a larger capacity expansion to meet the needs of energy storage projects of different scales. In addition, this product has a strong load capacity. The rated power of the string-type 2.5MW, 5MW and other power level cabinets can be increased by 5.6%, which can meet the long-term 115% overload output.

The significant features of the energy storage, conversion and boosting integrated cabin are:

Flexible configuration and efficient energy storage

The PCS single module of the energy storage conversion and boosting integrated cabin has a high capacity of 220kW and a strong power conversion capability. Through the precise management of one-to-one battery clusters, each cluster is ensured to operate independently, which improves the battery power utilization rate of each cluster and the charging and discharging capacity by more than 6%. At the same time, the energy storage conversion and boosting integrated cabin can support flexible stringing of 24 and 28 modules, realize diversified capacity specifications of 5MW and 6MW, and meet the needs of different specifications of battery cells in different scenarios. This not only improves the overall performance of the system, but also provides users with a more flexible and efficient energy solution.

Stable and reliable, widely used

The transformer of the energy storage conversion and boosting integrated cabin adopts a double-split structure, which improves the energy utilization efficiency while also improving the stability and reliability of the power system. The string-type PCS adopts a liquid cooling solution design, which can be used in harsh environments such as high wind and sand, high salt fog, etc., to provide customers with more reliable products. At the same time, the PCS using a liquid cooling system has a stronger overload capacity and provides a stronger conversion module for the energy storage system. These characteristics make the product have a wide range of application prospects in the field of energy storage.

Comprehensive functions and excellent technology

The integrated energy storage and conversion boosting cabin can meet the functional requirements of grid-type converters. The product has powerful functions such as inertia response, damping control, frequency modulation and peak regulation, multi-machine parallel connection, system black start, phase angle mutation tolerance, and strong short-circuit support. In addition, it can also support GOOSE high-speed communication, and can achieve a single-machine full-station communication response of less than 5ms, ensuring fast information transmission and response speed. With its excellent technical performance and functional integration, the integrated energy storage and conversion boosting cabin provides strong technical support for the stable operation and efficient management of the power grid.

The launch of the integrated energy storage and conversion boosting cabin marks an important breakthrough of Yapai Technology in the field of energy storage technology. On the road of promoting the development of energy storage technology, Yapai Technology has always kept pace with the times, actively invested in research and development, and explored new technical paths and application scenarios. At the same time, Yapai will also actively seek cross-field cooperation to promote the application and development of energy storage technology in more fields and contribute more to the sustainable development of the energy industry.
