Shenyang Shenyang Power Information Room Power Supply Scheme

Liaoning Electric Power Co., Ltd. is a large-scale state-owned enterprise formed on the basis of the former Northeast Electric Power Group Corporation. It was established in 1999 and belongs to the State Grid Corporation of China. The company takes the construction and operation of Liaoning Power Grid as its core business, and assumes the responsibility of providing strong, safe, high-quality, convenient and clean power supply for the sustainable economic development of Liaoning, and shoulders the responsibility of maintaining and increasing the value of state-owned assets. There are 14 municipal power supply companies, 1 ultra high voltage branch company, 6 construction companies, 4 mechanical construction companies, 2 training centers, 1 staff hospital, and 1 power survey and design institute. The power supply service area is 148,000 square kilometers and the service population is more than 43 million.

Shenyang Power Supply Company's communication center room serves as the central station of Shenyang Power Communication Network, and is also an important communication hub for the State Grid Corporation of China, Northeast Power Grid Corporation, and Liaoning Province. It provides special channels for the dispatching, command and control of power grids, marketing networks, and information networking systems in Shenyang, and it also carries centralized and tandem services for various information networks.

Project proposals:

The bureau's information room has installed 12 sets of server racks and uses two 120KVA (1+1) UPS mainframes for power supply. The actual load is about 400A (88KW). With the continuous increase of business, the existing power capacity does not meet the actual needs. Transform the communications room.

According to the actual situation, it is planned to use 240V DC power supply mode independently for some server devices in the bureau's information room to be stripped from the existing UPS power supply system. The actual operating current of equipment currently planned for cutover in the equipment room is 130A, and the operating power is 29KW. The current new equipment (1 minicomputer and 12 servers) is configured according to 50KW; the planned capacity expansion (9 server cabinets) is the total nominal value. Power consumption 84.8KW.

Taking into account the need for redundancy and capacity expansion in the later period, the equipment power of the entire computer room company is calculated based on the total capacity of 150 KW. The project uses a set of 150KW240V DC power supply system.

Configuring the Delta HVP Discrete DC system with a four-cabinet configuration. The AC input power distribution screen is independently configured. The monitoring and rectifier modules are integrated in the two rectifier cabinets, and the DC power distribution is separately listed. The other information room is configured with DC. Column head cabinet 2 sets; 48 48A modules are configured in advance, the system capacity is 240V/960A; 12 modules can be expanded in the later stage, and the total capacity is up to 1200A.

Adopting the advanced and mature technology and design concept of Zhongda Dentsu, it provides Zhongda Dentsu 240V HVDC power supply solution, which can not only be quickly established, but also can be flexibly planned and applied according to actual needs to help customers create a new generation of high efficiency. Energy-saving green room.

Project Summary:

The 240V HVDC power supply is recognized and applied by power customers with its advantages of high reliability and high efficiency. At the same time, this project is the first time that the power industry users have adopted the 240V HVDC power supply solution from Zhongda Dentsu. Under the background of the global hot big data era, 240V HVDC power supply solutions will be accepted, applied and promoted by more industries, providing a strong driving force for the data center business to take off.
