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.
