Description

Technical Field

[0001] This article belongs to the field of smart energy storage system integration technology, specifically involving a high-efficiency data processing device for a large-scale energy storage system. Background Technology

[0002] Globally, in-depth research and development of new and renewable energy sources, and the active pursuit of advanced methods to improve energy efficiency, have become a primary strategic issue of common concern to all countries. For a large country like China, with its massive energy production and consumption, this trend is particularly significant. On the one hand, China faces increasingly severe pressure to conserve energy and reduce emissions, and urgently needs to reduce energy consumption per unit of GDP and carbon emission intensity. On the other hand, continuous economic and social development is inevitably accompanied by stable growth in energy demand. Against this backdrop, vigorously developing the energy storage industry, especially electrochemical energy storage, which is currently technologically mature and has broad application prospects, has become an indispensable key link. It is not only a technical support for smoothing fluctuations in new energy output and improving the grid's absorption capacity, but also one of the core elements for building a new power system and optimizing the energy structure.

[0003] However, in the actual deployment and operation of large-scale energy storage systems, there are significant efficiency bottlenecks and maintenance pain points in the data acquisition and transmission links. The currently commonly used configuration mode of one device per storage unit, that is, each energy storage unit is equipped with a photoelectric switch, seems straightforward, but it brings many inconveniences: First, the data transmission link is extremely cumbersome. Each storage unit needs an independent switch to process and upload data, resulting in dense cabling, numerous interfaces, and complex physical connections within the system. Second, the management and maintenance costs are high and inconvenient. Maintenance personnel need to independently configure, monitor, and troubleshoot each switch, which greatly increases the workload and time costs. Third, the system has poor scalability and flexibility. When adding or removing storage units, the switch configuration needs to be added or removed simultaneously, which is a complex and error-prone process. This discrete data transmission architecture has become a key bottleneck restricting the efficient and intelligent operation of large-scale energy storage power stations.

[0004] In conclusion, given the global energy transition trend and China's unique energy development challenges, the strategic importance of electrochemical energy storage is undeniable. Addressing the inefficiency and high cost of data exchange in current large-scale energy storage projects is a pressing issue for promoting the healthy and large-scale development of the industry. Given the industry's emphasis on refined operation and cost control, there is an urgent need to explore and apply more efficient and economical measures to optimize the data exchange architecture. Addressing the drawbacks of the one-warehouse-one-machine model, an innovative model of multiple warehouses sharing a single high-performance core switch has emerged as a highly promising solution. This centralized and intensive data exchange method not only significantly simplifies physical cabling and reduces the number and cost of equipment procurement, but also improves data transmission efficiency and management convenience, enabling more unified and intelligent monitoring and maintenance. Therefore, promoting such efficient solutions is of significant practical importance and has broad application prospects for improving the overall economy, reliability, and intelligence of energy storage systems, and meeting the industry's core demands for cost reduction and efficiency improvement. Utility Model Content

[0005] As analyzed above, the currently widely adopted one-warehouse-one-machine configuration mode has many limitations and brings significant inconvenience in practical applications. To solve the above problems, this paper proposes an innovative design scheme that centrally manages multiple energy storage warehouses through a single switch. This intensive architecture significantly improves the flexibility of system deployment and operation, not only greatly optimizes work efficiency, but also effectively reduces overall costs.

[0006] A high-efficiency data processing device for a large-scale energy storage system includes: a first AC-side booster integrated chamber, a second AC-side booster integrated chamber, a third AC-side booster integrated chamber, a fourth AC-side booster integrated chamber, an energy storage unit, a multi-port optoelectronic switch, a physical communication link, a backbone communication line, and a data backend. These core components together construct a complete distributed data processing architecture.

[0007] Each compartment is set up independently, and each compartment is connected to a set of energy storage units, which significantly improves the system reliability and maintainability and simplifies thermal management and layout design;

[0008] The multi-port optoelectronic switch is located in the central area of ​​the four compartments and has a number of access ports corresponding to the number of compartments. This design minimizes the difference in the length of the physical communication link and creates the physical conditions for achieving isochronous transmission of data from each compartment to the switch.

[0009] The two ends of the physical communication link are respectively connected to the local data interface of the corresponding AC side booster integrated compartment and the independent physical port of the multi-port optoelectronic switch, ensuring independent transmission bandwidth and channel isolation for data of each compartment, avoiding data congestion and cross interference, improving transmission reliability, and facilitating fault diagnosis and link maintenance.

[0010] The data backend is connected to the backend communication port of the multi-port optoelectronic switch via the backbone communication line to receive and process data from each warehouse. This provides sufficient bandwidth to carry the massive data streams gathered from all warehouses, ensuring the timeliness and integrity of the data received by the backend processing system, which is a key link in achieving efficient data processing.

[0011] The location of the multi-port optoelectronic switch must ensure that the difference in data transmission delay between the four physical communication links is less than a preset threshold. This is crucial for accurate system status synchronization analysis, power coordination control, and rapid fault location in the background, significantly improving control accuracy and response speed.

[0012] The multi-port optoelectronic switch includes: warehouse access port, expansion port, and back-end communication port;

[0013] The warehouse has four access ports, each of which is connected to one end of a physical communication link.

[0014] The expansion port is used to connect backup monitoring equipment;

[0015] The backend communication port is used to connect to the backbone communication line;

[0016] Multi-port optoelectronic switches ensure data transmission priority and reliability, while reserved expansion ports provide seamless access for future system upgrades and additional monitoring, enhancing the system's flexibility and adaptability.

[0017] The physical communication link is a composite cable structure, including: an inner layer of twisted-pair cores, a middle layer of metal shielding mesh, and an outer layer of waterproof sheath;

[0018] The inner twisted-pair cable provides a reliable transmission foundation, the middle metal shielding effectively resists strong electromagnetic interference, and the outer waterproof sheath ensures long-term protection and durability in outdoor or humid environments. The combination of these three layers greatly improves the stability of the communication link in complex industrial environments.

[0019] The local data interface is located on the outer wall of the integrated AC booster chamber. The interface protection level reaches IP65, which facilitates on-site installation, maintenance and connection, effectively prevents dust intrusion and low-pressure water spray from any direction, and ensures that the interface can work stably for a long time in harsh outdoor or industrial environments, reducing failures caused by environmental factors.

[0020] The extended port connects to the environmental monitoring unit, including temperature and humidity sensors and vibration detectors, enabling real-time monitoring of the energy storage unit's operating environment and equipment mechanical status. This enriches the dimensions of the backend data, providing crucial support for predictive maintenance, thermal management optimization, and safety early warning, thereby improving the level of intelligent operation and maintenance and safety.

[0021] The backbone communication line is connected to the back-end communication port of the multi-port optoelectronic switch and the communication port of the data back-end at both ends, ensuring that the aggregated data of the entire system can be transmitted to the back-end processing center efficiently and without bottlenecks. This is the ultimate physical guarantee for the entire system to achieve efficient data processing.

[0022] Beneficial effects:

[0023] This device adopts a distributed architecture, with four independent AC-side booster integrated compartments connected to the energy storage unit. Equipped with IP65-protected external interfaces, it enhances system reliability, maintainability, and environmental adaptability. A multi-port optoelectronic switch is centrally located, connecting each compartment via composite cables of equal length, ensuring isochronous data transmission, channel isolation, electromagnetic interference resistance, and waterproofing. This lays the foundation for accurate status synchronization, rapid fault location, and power coordination in the background, significantly improving control accuracy and response speed. Dedicated backbone communication ensures bottleneck-free transmission of massive amounts of data. Reserved ports on the switch support the expansion of environmental monitoring units, enriching data dimensions to optimize predictive maintenance, thermal management, and safety early warning, thereby improving intelligent operation and maintenance levels, security, and system scalability.
