0.007秒能干啥？新疆的电“闪送”到重庆！

Core Insights - The Hami-Chongqing ±800 kV UHVDC project is a significant infrastructure development that enables the transmission of electricity over a distance of 2260 kilometers, facilitating the transfer of energy from Xinjiang to Chongqing in just 0.007 seconds [3][5]. Group 1: Project Overview - The Hami-Chongqing ±800 kV UHVDC project is the first UHVDC project connecting Northwest to Southwest China, starting from the Barkol Converter Station in Hami, Xinjiang, and ending at the Yubei Converter Station in Chongqing [5]. - The project is designed to support a total installed capacity of 14.2 million kW, with over 70% of this capacity coming from wind, solar, and thermal energy sources, setting a new record for similar projects [7]. Group 2: Energy Impact - The project is expected to deliver over 36 billion kWh of electricity annually to Chongqing, with approximately half of this coming from renewable energy sources, which equates to a reduction of about 6 million tons of coal consumption each year [7]. - The two converter stations are crucial for the "Xinjiang electricity into Chongqing" initiative, enabling large-scale and long-distance transfer of renewable energy while maintaining the stability of power supply by controlling fluctuations within 5% [9]. Group 3: Resource Potential - Xinjiang has a technical potential for wind energy of 780 million kW, accounting for 17% of the national total, and a solar energy potential of 1.6 trillion kWh, representing 40% of the national total, indicating a vast untapped resource [11]. - The UHVDC project addresses the energy supply and carbon reduction pressures faced by central and eastern provinces, making it a key solution for balancing energy distribution across regions [11]. Group 4: Historical Context - Since 2010, Xinjiang has exported over 900 billion kWh of electricity through two AC and two UHVDC channels, with approximately 30% of this being renewable energy, benefiting local communities [13].
