Polaris Smart Grid Online News: At the end of December, 4 new subway lines will be put into operation. The number of Beijing subway lines will reach 16, and the total mileage will exceed 440 kilometers. Subway operation is inseparable from the power supply. How to ensure the safety of subway lines? To this end, the reporter yesterday followed the study and implementation of the spirit of the 18th National Congress of the People's Liberation Army. The fifth branch of the report group came into the State Grid Corporation of Beijing and the Songjiazhuang substation, and conducted an on-site interview on the construction of Beijing's rail transit supporting power facilities. According to the introduction of Beijing Electric Power Company, Beijing rail transit adopts internationally advanced decentralized power supply, and even if a power station stops completely, it will not affect power supply. Decentralized power supply is to build a 110-kilovolt substation near the track, distribute the main power distribution room with double-trip 10kV power, and then distribute power to the power distribution rooms on both sides of the station via the main power distribution room. This has the advantage of achieving mutual support between different power points on a single track line. In other words, when one side is equipped with a fault, the closing is provided by the other side. Yesterday, the reporter went to the Songjiazhuang transformer station on the ground to see that, in the equipment room on the ground floor, 110 kV transformer equipment is operating in a quiet and orderly manner, each of which shows the name of the power supply object, there are two sets of power supply system. Our substations use the most advanced equipment and technologies in the country. Zhang Kunming, deputy chief engineer of Fengtai Power Supply Company, told reporters that rail transit power supply is currently the main load of Songjiazhuang substation, which can account for 70% of the load of the entire substation, mainly including Yizhuang Line Parking Lot, Songjiazhuang Gonglian, Line 10 Songjiazhuang Station and 10 Line parking lot construction.
