Beijing's new airport supporting electric multinomial black science and technology

The reporter understands from its recently Beijing electric power company, to meet the large international aviation integrated transport hub the requirement of the high reliability of power supply, the company built & other; 1 + 2 + 2 + 2' 7 auxiliary transformer substations, the expansion of daxing international airport in Beijing 500 kv double loop network power supply system, into the distance clean electricity; The forward, planning & other; 1 + 2 + 3 + 4' Ten substations, realize the source of two 500 kv, 220 kv, 110 kv chain structure partition running, providing strong grid support and abundant power supply capacity. Distribution network, formed in the terminal area, airfield, public area such as the area 25 them open and close, 15 three power station power supply structure, power supply reliability of 99. 9999% to the international first-class standards.

　　“ 1 + 2 + 2 + 2' Which is 1, 2, 500 kv substations 220 kv substation, 2 red lines - kv Yang area, zhang household substation in early July and put into production; Red line with zhang hua, built substations in September 2017 and put into operation in early July 2018; Red line with the new airport east, and west substation will be put into production, in the years after the two substations put into production power generation, for Beijing daxing international airport terminal, the airfield area directly provide abundant and reliable power supply guarantee.

the construction aspect, Beijing electric power innovation adopted the assembly of prefabricated steel structure construction. Among them, the new airport west substation during the process of civil prefabricated steel structure in alternative reinforced concrete pouring construction, the steel structure by manufacturer production ahead of schedule, transportation to the scene assembly directly, no dust homework, environmental protection and energy saving, compared with the traditional operation project cycle save nearly 2 months.

in addition, the Beijing electric power innovation adopted aluminium magnesium manganese outside wall construction technology, the new airport west substation wallboard has self rust resistance, service life can reach more than 50 years. Not only can effectively prevent wall cracks, and the construction is influenced by season. Compared with the traditional external wall, working procedure and process more simple and save project cycle for nearly three months.

Beijing daxing international airport for the first time in domestic by electric power company is responsible for the overall internal substation construction and operational work late at the airport. So far, in the construction of new airport form a complete set of power grid, has a number of black technology application in operational aspect.

　　“ New airport west substation each cable is equipped with optical fiber longitudinal protection channel, in the event of failure, can be achieved within of a second 10 kv cable fault isolation, greatly shorten the worth a power outage time, & throughout; The characteristic of the new airport west substation main control indoor players Yuan Baochao introduction, & other; Beijing electric power innovation using the intelligent inspection system, prevention and control of relying on & lsquo; Internet + & rsquo; Concept, in the construction phase synchronization built variety, full time and comprehensive prevention and control of intelligent inspection system, mainly including industrial TV monitoring, intelligent security, face recognition and tracking, etc. ”

it is understood that in the process of the new airport substation running late, Beijing power also will use the distribution network automation, & other Big Internet + data + mobile operation & throughout; And other advanced means and cable ultra-low frequency dielectric loss test and other advanced equipment, power grid equipment 24-hour monitoring of disposal, operation risk assessment, power grid fault accurate positioning and quickly isolate self heal and repair one-stop services, guarantee of the airport customers electricity security and stability.

the new matching grid operational innovation is one of the biggest bright spot inspection robot adopts intelligent, to achieve automatic and intelligent inspection work, network, informationization. Inspection robot intelligent inspection with high efficiency, high inspection accuracy, high efficiency, high operation safety management, inspection coverage.

in the center of the new airport substation 104 kv switch room, reporters saw a orange robot in sliding around, head up and down adjustable, can turn the arm. “ The application of intelligent inspection robot, promote efficiency of the inspection. A single check points about 1 - artificial inspection time 2 minutes, and the robot in 10 - single point inspection time 30 seconds, and can synchronize data record, analysis and alarm etc, at the same time inspection accuracy is higher, the identification accuracy of intelligent inspection system based on robot stay above 90%, accurate and reliable, no human, environment and so on subjective and objective factors interference, implement the visualization and intelligent management of the station equipment and display. ” Yuan Baochao is introduced.

in addition, the intelligent inspection system based on robot can collect multidimensional testing data, a simultaneous analysis, management, alarm and fault prediction, put an end to the traditional manual inspection data dispersed, deal with the problem of low efficiency, formed a comprehensive smart new test mode.

Yuan Baochao said: & other; Manual inspection is mainly on the voltage, current and other main meter and environmental view, intelligent inspection system can realize to all equipment, meter, switch state, indicator light, such as universal coverage and intelligent recognition, coverage, greatly increasing the equipment. ”
