Jiquan DC transmission power breaks world record
Time of issue:
Aug 25,2022
Since the beginning of summer,the East China region has been affected by continuous high temperatures, resulting in a significant increase inelectricity consumption. During the critical period, state Grid Corporation of china adhered to the national"one game" strategy and plaved a rolin resource allocation ofthe large power grid. t has twice increased the load of Jiquan Dc transmission, bundled Xiniang's abundant coal powel and cdean enerey such as wind nower photovoltaics, and solar enery, efectively aleviating the tense situation of nower supply in Fast china to the greatest extent possible,fuly demonstrating the responsibility and responsibility of being a "maior power tool and a central enterprise "capable of withstanding".
Jiquan DC transmission power breaks world record
Since the beginning of summer,the East China region has been affected by continuous high temperatures, resulting in a significant increase inelectricity consumption.

Xinjiang Electric Power has formulated a special guarantee work plan established a station and emergency linkage mechanism for leaders and experts at all levels, and selected more than 20 professional backbone personnel in maintenance and testing to strengthen on-site supply guarante forces. since Augut,the operation and inspection personnel of stat Grid xinjiang Electric Power Organization have fully utilized online monitoring,live detection, and inteligent inspection platforms to carry out joint special inspections and maintenance ofsupporting transmission and transformation equipment, The focus has been on precise temperature measurement,ultraviolet detection, data analysis, etc, for the converter valve, converter, Dc field equipment, and transmission lines in Changji Converter station, The stationed fire brigade has been organized to conduct pracical emergency drills, fully ensuring the safe and stable operation ofequipment. Under the condition of no reference for reference, the Northwest Branch of State Grid organized and carried out rolling calculatior and took the lead in building a full electromagnetic simulation model for the Ac/Dc power grid in chinaand analysis work for nearly three years Using the fullelectromagnetic transient simulation tool, stability characteristics and control scheme verification were carried out, and the stabilit characteristics of the Northwest power grid after the high-power operation of Jiquan Dc were analyzed in detail. Hami Wind Power was evaluated The impact of spatiotemporal distribution changes of diferent new energy sources such as Hexi wind power and Haixi photovoltaic on the impact of Jiguan Dc fault.
In order to ensure the operation and maintenance of eguipment at a power of 11 milion kilowatts, State Grid Power has increased investment in personnel, technoloev, and equlpment, As a deep patner of state Grid corporation ot china, Ambes has asisted more than ten substations multiple times, using high-precision design operation consoles and high torque multi degree of freedom operation consoles, combined with innovative modular design, to provide new products that are in line with the current trend, high standard and epidemics, carefully monitor, inspect, and maintain, fully ensuring the safe and stable operation of the Xinjiang Electric Power Dc artery, and contributing xiniang's strength to the national power supply guarantee. The transmission power of changi Guquan + 1100 kv ultra-high voltage direct current transmission proiect has been increased to 1. milion kilowatts for operation, with a daily transmission capacity of241,9 milion kilowatt hours, setting a record for the world's highest transmission power of direct current transmission projects.
