"The length of the power supply line of 10 thousand volts and above in Chengdu is more than 420,000 kilometers, ensuring the safety and reliability of power supply is the most basic and important work. Liu Yanqin, deputy to the Municipal People's Congress and Secretary of the Party Committee of the Substation Maintenance Center of the State Grid Chengdu Power Supply Company, said.
As the "power grid doctor" of the substation maintenance center, Liu Yanqin has long been concerned about the health of the power grid, "Among the factors about the safety of the power grid, the hidden dangers of construction such as the contradiction of tree lines are more prominent, and the suggestion I bring is to strengthen the control and governance of these two aspects." ”
Liu Yanqin said that many areas of the city are lush with seedlings, and there are a large number of hidden tree barriers in the power channel, and for a long time, the operation safety of power grid equipment needs to coordinate and deal with more than 4,000 hidden tree barriers every year; According to incomplete statistics, there are more than 3,000 external hidden dangers of power facilities with a voltage level of 10 thousand volts to 500 thousand volts in Chengdu, and the control work is still difficult.
To strengthen the control and governance of these two aspects, my suggestion is to establish a normalized collaborative work mechanism, clarify the specific work responsibilities and work processes of relevant functional departments, and at the same time unify the standard for the disposal of hidden dangers in the tree line, and implement the construction operation permit system in the power facility protection area, which can greatly reduce the risk of large-scale power outages in regional cities caused by faults. Liu Yanqin said.
In addition to the management of hidden dangers, the promotion of key projects is also related to the stable power supply of the city. According to Liu Yanqin, the State Grid Chengdu Power Supply Company is currently making every effort to promote the construction of 220 thousand volt Houzimen substation, as the first 220 thousand volt underground substation in the western region, after the completion of the project, it will provide 720,000 kilowatts of power support for Chunxi Road, IFS, Kuanzhai Alley, Wenshufang and other important commercial and living areas in the second ring road, improve the power supply capacity of the central urban area by 75%, and provide important energy security for the international financial highland, high-end business gateway and Tianfu Cultural Center in the core area of the city.
