Huawei Modular UPS Inserts Reliable Wings into Chongqing Airport
The development of new generation information technology, such as big data, cloud computing and Internet of Things, has promoted the transformation and upgrading of airports to intellectualization. On the premise of ensuring information security, air traffic management, airline operation management, airport operation management and other business are gradually developing to "business cloud, data integration, innovative application".
As a hub of modern transportation, the airport undertakes the important mission of people's convenient travel and cargo air transport. Once the airport is paralysed, the consequences are unimaginable and the economic losses are huge.
Chongqing Jiangbei International Airport (Chongqing Jiangbei International Airport), located in the two streets of Yubei District, Chongqing City, China, 19 kilometers from the city center, is a 4E class Civil International airport. It is one of the eight major hub airports in China and is the fifth airport in China to implement a 72-hour transit visa-free policy in 2013.
The airport has two terminal buildings, T1 (International, Hong Kong, Macao and Taiwan) and T2 (Domestic) with a total of 200,000 square meters. In 2015, Chongqing Jiangbei International Airport completed 32.4 million passenger throughput, an increase of 10.72% over the previous year. Passenger throughput ranked ninth in domestic airports and sixth in China's top ten airports.
Airport terminal is the "central nervous system" of modern airport. It has a complex and complete network system. It is an important consideration for airport managers to ensure the uninterrupted power supply of the terminal's data room and related key infrastructure. UPS uninterruptible power supply equipment used in the airport is one of the most critical security equipment in the whole aviation system, which directly affects the stable, reliable and efficient operation of the airport. Therefore, how to select a reliable UPS is a difficult problem faced by the Construction Department of the new terminal of Jiangbei International Airport in Chongqing.
The primary concern of the Construction Department of the new terminal building is the power supply system of the equipment. Traditional power supply system uses decentralized power supply, that is, one equipment corresponds to a small UPS. For example, security access, check-in island, boarding gate, baggage transfer and other original use of 20-80 kVA UPS power supply. Not only is decentralized maintenance inconvenient, but once a failure occurs, it requires the maintenance of the manufacturer and maintenance time can not be guaranteed, which brings great trouble to the airport mechanical and electrical maintenance department. Decentralized small UPS is inefficient, most of the current network UPS efficiency is less than 90%, can not meet the current demand for energy conservation and emission reduction.
After investigating the existing scheme and discussing it fully, the airport construction department decided to adopt regional centralized power supply to replace the original decentralized power supply system. The original security channel, check-in island, boarding port, baggage transfer and other decentralized small capacity UPS power supply were regionally supplied by large capacity UPS centralized power supply. Considering the voltage drop and other issues, the power supply distance of regional load could not exceed. Over a certain range, UPS centralized power supply capacity is generally more than 200 kVA. Through centralized power supply, the power supply efficiency of the system will be greatly improved, and the target of energy saving and emission reduction will be achieved. At the same time, centralized power supply also solves the problem of decentralized maintenance. Centralized power supply requires higher reliability of the system. The reliability of power supply system can be improved by using 2N power supply system architecture and redundant double bus system. No downtime risk will occur for a single fault.
The Construction Department of Chongqing Jiangbei International Airport terminal passed strict bidding examination, and finally chose Huawei UPS5000-E modular UPS solution to escort the new terminal building.
High reliability: Huawei modular UPS5000-E adopts the most advanced topology structure in terms of reliability, adopts full modular design and provides high reliability N+X distribution scheme, which can achieve the shortest MTTR (average fault repair time) industry.
Low load and high efficiency: This is another important reason why Huawei modular UPS5000-E has won the favor of Chongqing Airport Group. 20% load efficiency is up to 95%, 40% load efficiency is up to 96%. Compared with the traditional UPS with about 90% efficiency in the industry, Huawei UPS5000-E will bring millions of RMB-level electricity savings to Chongqing Jiangbei Airport every year.
Easy Maintenance: High density modular N+X system replaces the original 1+1 tower crane, which saves at least half of the area, supports hot plugging and plugging of functional components, and can be replaced by ordinary engineers in 5 minutes, and the fault can be quickly eliminated.
As the world's leading provider of information and communication solutions, it took only a few years for Huawei to enter the UPS market and become the "leader of modular UPS". Now it has been widely used in the world. The industry covers many key business areas such as transportation, ISP, finance, government, energy, and other key loads such as medium and large data centers, security systems and automation production equipment. Provide uninterruptible power supply to provide users with all-round power guarantee.
Today, with the vigorous development of China's civil aviation industry, Huawei UPS solutions will provide reliable wings for flight.
