Product Description


1. Product Introduction of The AC / DC Integrated Power Supply


HDHY2000 integrated AC/DC power supply system is introduced by Huadian Hongyuan Company. The power supply system integrates the design, configuration and monitoring of AC power supply (AC), DC operating power supply (DC), special AC uninterruptible power supply (UPS), special power inverter power supply (INV) and communication DC converter power supply (DC-DC) for substation stations.


The system integrates the station power supply comprehensively: The station AC power supply system, DC power supply system, inverter power supply system, communication power supply system unified design, monitoring, production, debugging, service.




Through the integrated monitoring module, all subsystems of the station power supply are networked. Realize the information sharing of the station power supply, and establish the digital power supply software platform. By intelligently modularizing all switches of the station power supply, Decentralization of centralized functions, no secondary wiring outside the module and no cross-screen secondary cable are realized, and a digital power supply hardware platform is established. The integrated monitoring module communicates with the upper computer system through Ethernet interface and IEC61850 protocol, which makes the station power supply system become an open system.


2. Product Parameter (Specification) of The AC / DC Integrated Power Supply


Compared with traditional AC/DC power supply, take two AC incoming cables+two groups of charging modules+two groups of power storage (300A) as an example.


AC and DC integrated power system is not a simple mixture of AC and DC power system. Its main technical characteristics are as follows: Comparision of AC/DC integrated power integrated power supply configuration with traditional AC/DC power supply.

Comparison of Functional Differences


(Ac and DC separate design, respectively equipped with AC monitoring, DC monitoring, no unified communication interface;

Set and operate battery packs, communication battery packs and UPS;

Operation mode adjustment: AC, DC respectively;

No intelligent secondary power distribution management;

The surge protection is configured separately. Waveform interference cannot be treated comprehensively.

Ac and DC integrated monitor is responsible for AC and DC monitoring, to the last communication interface;

Cancel the communication battery group, by DC/DC directly hanging on the operation battery group instead; Cancel the UPS and connect the inverter power supply to the operating battery instead.

The station power supply operation mode is unified, and the integrated monitor automatically adjusts each operation mode according to the change, so as to make the system run well.

Intelligent secondary power distribution: intelligent lighting system, intelligent fan system, intelligent access control system, intelligent air conditioning system and other auxiliary equipment system to achieve intelligent.

Unified lightning protection configuration and waveform management for station power supply,


Integrated monitor = AC monitor + DC monitor;

Integrated battery = Operation battery + communication battery +UPS battery;

Automatic adjustment of station power supply operation mode;

At the same time, the intelligent auxiliary equipment system is realized in the integrated design.

Integration to solve the problem in a unified and comprehensive way, the solution is more effective.

Monitor cost saving: about 10,000 yuan; Commissioning fee.

Battery pack integration, deducting capacity increase factor, can reduce at least communication charging module, communication battery room.

Cost saving: communication charging module 5000 + communication battery room 25000 = about 30000;

Automatic adjustment of station power supply operation mode: it can reduce operation cost;

Intelligentization of auxiliary equipment system can reduce operation cost and improve operation reliability;

Can save the auxiliary equipment system intelligent transformation cost 20,000 yuan;

Power surge protection and waveform management can reduce repeated configurations and save some costs.





Subtotal: functional investment can be calculated cost savings: about 60,000 yuan;  Fees cannot be calculated.

Panel To Compare

Ac panel: 2

Dc panel: a total of 10 charging screens, two feeder screens and six battery screens.

Communication battery room: 1 room, 2 sets of 48V/ cell 2 v100ah batteries

UPS: 1 for computers and printers

A total of 12 screens are required

Ac screen: 2 + integrated monitor + accident lighting;

DC screen: charge screen + two feeder screens, feeder + insulation test screen 1, communication DC/DC+ inverter screen 1, battery + battery inspection screen 6, a total of 10.

A total of 12, all feeders to achieve four remote, at the same time due to load difference to achieve intelligent management of auxiliary equipment. 


The integrated connection is simple and convenient, reducing the workload of construction personnel.

Save cable cost of 2,000 yuan.

Supply Manufacturers



Simplify contact and maintenance

Save 10 working days *100 yuan/day = 10,000 yuan


Installation cost 4 x 2000 = 8000 YUAN

(The total maintenance cost for one person/time is 2000 YUAN)

Installation cost: 2000 yuan

Convenient installation and maintenance, long-term maintenance costs greatly reduced.

Initial installation cost savings of nearly 0. 60000 yuan.

Greatly reduce operation and maintenance personnel, save money.

Save personnel expenditure of 0.75 million yuan/month (calculated according to 2500 yuan/person monthly salary) save personnel salary of 900,000 yuan in 10 years


The system is configured with two ac incoming cables, two charging modules, and two batteries (300A),based on the above comparison results, it can be found that the initial investment cost of integrated power supply is 60,000-90,000 yuan lower than that of traditional station power, and the salary of long-term maintenance personnel can be saved 900,000 yuan in 10 years.The above are conservative estimates for reference only. Because of ac-DC integration brings intelligence, security and other recessive savings, social benefits can not be estimated.

HDHY2000 intelligent station power supply AC-DC integration system is a model technology to practice the "two types one" design.



3. Product Feature And Application of The AC / DC Integrated Power Supply
