Functions and technical parameters of DPS distributed power system. As an integral part of my country's power system, DPS distributed power supply is an important supplement to the large power supply. It is organically unified with the large power supply and the large power grid and is indispensable. Distributed power system DPS refers to a small modular, environmentally compatible independent power supply with a power of several kilowatts to 50MW. The distributed power supply DPS module is directly integrated inside the IDC cabinet.

　　Functions of DPS distributed power system

　　1. DPS distributed power supply is a revolutionary technological breakthrough in uninterruptible power supply UPS power supply system. It adopts ultra-high-speed static switching switch to switch the backup power supply at a speed of <2ms, so that the main power supply circuit and the backup power supply circuit can be completely isolated, effectively extending the Battery life and discharge time. The precision voltage-stabilizing charging unit with dormant duty rotation system can effectively charge and maintain the battery pack, eliminating the hidden danger of soft faults caused by poor charging and maintenance;

　　2. The DPS distributed power supply system solves the energy consumption and soft failure risks caused by many uncertain factors caused by the AC and DC conversion of the UPS uninterruptible power supply system; it also solves the problems caused by the chemical molecular structure characteristics of the battery material and the physical structure of the power supply load. The dynamic changes overcome the problem of resource consumption and avoid potential system disasters caused by hidden faults when the system uses backup batteries for emergency use;

　　3. DPS distributed power supply solves the technical problems of long-term UPS battery monitoring and long-term stable activation of chemical molecular materials; it also solves the system disaster caused by the long switching time of AC UPS to various equipment and devices. ;

　　4. DPS power supply has the characteristics of high system efficiency, low energy consumption; high reliability, low harmonics; long life, low pollution; high performance and low cost. The operating noise of the system is less than 30dB, and it is easy to expand online and maintain. It is a highly reliable energy-saving product.

　　5. Distributed DPS energy is a system that determines unit configuration and capacity scale based on the optimization of resources, environment and economic benefits. It pursues the maximization of terminal energy utilization efficiency and adopts demand-responsive design and modular combination configuration to satisfy users. A variety of energy needs can optimize and integrate supply and demand in resource allocation.

　　6. Distributed DPS power supply relies on advanced information technology and adopts intelligent, networked control and remote control technology to achieve unattended on-site operation. At the same time, it also relies on the socialized energy technology service system of the energy service company system to achieve professional operations in investment, construction, operation and management to ensure the safe and reliable operation of each energy system.

　　Application cases of distributed power system DPS

　　The perfect integration of distributed power system DPS and computer room micro-module. In terms of computer room micro-modules, inter-row refrigeration and mesh cabinet cold aisle closure are used to build high-density, high-efficiency, green and energy-saving operations. According to the power consumption and installation space requirements of IT equipment, configure cabinets, cabinet row-level air conditioners, and row-level power distribution to ensure good heat dissipation of equipment, orderly airflow organization, efficient and energy-saving systems, and easy control and management. In terms of DPS backup source, it adopts the distributed DPS power system solution, lithium battery system, fully modular design, green and energy-saving. There is no need to configure a separate UPS room and battery room, which effectively improves the space utilization of the computer room.

　　The DPS distributed power system is different from the traditional centralized UPS system. In the early stages of customer communication, it has won the trust of users with its distinctive features such as on-demand deployment, flexibility and speed, green energy saving, and improved space utilization. Reduce host equipment investment, no need for 2N configuration, and easily achieve the reliability of 2N configuration. Even if multiple adjacent devices fail, only the corresponding cabinet will lose power, and the scope of impact will be minimal.

　　Distributed power supply DPS is a new energy production system with low pollution emissions, flexibility and convenience, high reliability and high efficiency.
