For the airport, electrification is not only to provide power guarantee for the whole airport, but also to cover the safe operation and efficient operation and maintenance of equipment. Schneider Electric believes that the airport itself is a complex infrastructure composed of many equipment and systems, which needs to be operated step by step, and different solutions are deployed in different regions to deal with possible hidden dangers in different regions, so as to achieve more effective life cycle management optimization. Chen Ke, senior department manager of Schneider Electric and application expert of Schneider Electric industry, mentioned in the white paper research on the application scenario of power quality instruments in the airport industry that with the increase of airport monitoring, control and a large number of electronic information collection equipment, the faults caused by voltage sag / rise gradually appear. Therefore, electrical safety, reliable power supply, moderate advance and economic rationality are the primary factors to be considered in the construction of “four type airport”. At the same time, the power quality meter can not completely replace the multi-function meter, and the combination of the two is the best choice.

The safety of power supply and distribution system is particularly important to ensure the uninterrupted power supply of the airport. Author of the white paper “Application of automatic transfer switch in air traffic control system” – senior expert of Schneider Electric Liu Haochuan, head of Schneider wangao industry application, said: “With the rapid growth of aviation business, higher requirements are put forward for the operation stability of air traffic control equipment. The uninterrupted power supply of equipment has become an indispensable link in the guarantee work. All equipment and systems in air traffic control engineering should be based on a safer and reliable power supply and distribution system. Take wbtpc bypass isolation automatic transfer switch with maintenance bypass ATS as an example, which has mechanical connection Lock, electrical interlocking, logic interlocking of control device, double bypass design, safe and convenient operation and maintenance and other characteristics play an important role in both the switching of municipal power supply and emergency power supply and UPS power supply system. They are the key nodes to provide important guarantee for the conversion of ATC power supply system. “

In addition, Guo Liqing, an industry application expert of Schneider Electric airport, also mentioned in the white paper “selective cooperation of low-voltage distribution system of air traffic control center” that the low-voltage distribution system of air traffic control center has two typical characteristics: first, there are many levels of low-voltage distribution protection, and second, the load level is high. Therefore, realizing the full selective cooperation between the upper and lower levels of low-voltage circuit breaker is very important to ensure the uninterrupted power supply of key loads such as data room and control position. Therefore, the ZSI function of the circuit breaker in the main distribution system not only ensures the full selectivity, but also minimizes the risk of damage to the mechanical strength of the busbar caused by the thermal effect of short-circuit current in the whole life cycle of the air traffic control distribution system.

Integrated architecture enables green and efficient airport management

As one of the busiest public places in the world, the uninterrupted operation of the airport has become its unshakable development goal. However, with civil aviation increasing energy conservation and emission reduction, the low-carbon and green development of the airport has become a hard standard. Therefore, while building a four type airport to ensure safety, we also need to take into account the green development goal. Schneider Electric relies on its rich experience in the airport industry and is based on ecostruxure ™ Architecture and platform, focus the digital scheme on three subsystems: intelligent power distribution, building equipment management and intelligent lighting, and adopt the core architecture of medium and low voltage integration, software and hardware integration and strong and weak power integration to enable the construction and operation of green four type airport in the new era.

Author of digital architecture and application scheme for airport industry – Schneider Electric senior solution architect Li Jiandong, head of Digital Scheme Application in Schneider Electric airport industry, said: “Schneider Electric is rich in business operation and technology accumulation of the airport. With digital technology and solutions composed of three subsystems and three core architectures, Schneider Electric has built a large electromechanical operation and maintenance management platform of the airport. In terms of intelligent distribution system, Schneider Electric has developed intelligent distribution products and solutions that meet the operation and maintenance needs with the integration of medium and low voltage and software and hardware as the core Build a safe, stable and efficient airport power supply and distribution system to ensure the safe and continuous operation of business; In terms of building equipment management system, energy, automation and software are integrated to realize the monitoring and control of a variety of electromechanical equipment. Combined with digital technology, an electromechanical equipment operation and maintenance management platform with unified all IP architecture is provided based on the software platform to define the airport building with software and drive the digital transformation of the future airport with data; In terms of intelligent lighting system, Schneider Electric provides the airport with intelligent lighting scheme with the characteristics of connection, linkage, intelligence and energy saving, so as to save energy consumption. ” It is not difficult to see that Schneider Electric not only organically integrates intelligent power distribution system, building equipment management system and intelligent lighting system, but also optimizes and improves operation management and energy efficiency through the integrated strong and weak current integration platform, so as to solve the key needs of safety, energy efficiency and digitization in airport operation and accelerate the construction of green smart airport, Help achieve the “double carbon” goal.

Share data with digital software to realize intelligent upgrading of the airport

In the construction of smart airport, the sharing and effective utilization of internal and external information of the airport with the help of interconnection, digitization and other technologies is the basis for improving the quality of smart airport. With all kinds of power electronic equipment continuously put into the airport power distribution system, the digital software can help engineers analyze and calculate the power quality and ensure the safe operation of the airport system. Zhao Liang, a senior technical expert of etapchina, mentioned in the white paper on the application of ETAP power quality module in the airport industry that there is a dual V certified equipment library in ETAP software. After the engineer converts the overall power supply and distribution system model of the airport into ETAP digital single line diagram, it can be directly dragged into the grid corresponding to IEC / ANSI symbols. ETAP software supports the import and export of DWG format files and the import based on Excel, XML, txt and other standard data formats, which can shorten the drawing time of engineers and improve work efficiency.

In addition, ETAP software can not only define the equivalent power grid, generator, inverter, UPS, frequency converter and other equipment as harmonic source, but also select the harmonic source model of ETAP or the harmonic source model established according to customer data in the library to calculate the harmonic source power flow and provide data support for the selection of filter. The powerful simulation analysis function of ETAP software can improve the accuracy of scheme design and avoid increasing equipment investment due to excessive capacity design. At the same time, ETAP software can also reduce the probability of electrical accidents, improve the security of airport power supply system, and then reduce the cost of maintenance and updating equipment.

Accelerate the construction of type IV airport and welcome a green future together

As a complex public facility, driven by market demand and the application of new technologies, the airport is undergoing digital transformation at an unprecedented speed from design, construction to operation and optimization. Schneider Electric, a global digital transformation expert in the field of energy management and automation, has been deeply engaged in the airport industry for many years and is well versed in China’s development concept of the construction of four types of airports and four strong air traffic control.
