日前，随着大同—怀来—天津南1000千伏特高压工程成功跨越1000千伏特高压锡廊一线、锡廊二线，该工程大规模集中跨线施工作业全面完成，标志着这条“西电东送”新通道进入全面架线阶段。这是国网冀北电力有限公司推进电网提档升级、加快新型电力系统构建的又一重要举措。

Recently, with the successful crossing of the 1000-kilovolt ultra-high voltage transmission line between Datong - Huailai - Tianjin South by the 1000-kilovolt ultra-high voltage transmission line between Xilang and Xilang II, the large-scale concentrated cross-line construction work for this project has been fully completed. This marks that this new "West-to-East Power Transmission" channel has entered the stage of full-line erection. This is another important measure taken by State Grid Hebei North Power Company to promote the upgrading of the power grid and accelerate the construction of the new power system.

冀北地区是“西电东送”“北电南送”能源交通要道。可靠电网是将新能源送出冀北，抵达负荷中心的重要枢纽。“十四五”时期，国网冀北电力持续加大电网建设力度，先后建成投运2项特高压工程，完成10项500千伏新能源配套电网工程，形成以京津冀北1000千伏特高压大环网为支撑的骨干网架，张家口、承德两大新能源基地构建起多层级、多通道的清洁能源外送格局。

The Hebei North region is a key transportation route for "electricity transmission from the west to the east" and "electricity transmission from the north to the south". A reliable power grid is an important hub for delivering new energy from Hebei North to the load centers. During the "14th Five-Year Plan" period, State Grid Hebei North Power Company has continuously strengthened power grid construction, and has successively completed two ultra-high voltage projects and 10 500-kilovolt power grid projects for new energy, forming a backbone grid structure supported by the 1000-kilovolt ultra-high voltage large ring network in the north of Beijing-Tianjin-Hebei region.

越织越密的电网骨架，如何将清洁能源送得更稳、更远？数字化、智能化赋能是关键。

The increasingly dense grid structure: How to deliver clean energy more steadily and over greater distances? Digitalization and intelligence empowerment are the key.

在设备运维领域，国网冀北电力依托“空天地”一体化智慧运维体系，融合卫星遥感数据、线路杆塔可视化设备和无人机采集图像，在人工智能技术辅助下实现线路隐患秒级识别，巡检效率较传统模式提升6倍，有力保障了特高压骨干通道的安全稳定运行。

In the field of equipment operation and maintenance, State Grid Hebei Electric Power relies on the "space-ground-air" integrated intelligent operation and maintenance system, integrating satellite remote sensing data, line pole tower visualization equipment and drone-collected images. With the assistance of artificial intelligence technology, it can achieve second-level identification of line hazards in an instant. The inspection efficiency has increased by 6 times compared to the traditional mode, effectively ensuring the safe and stable operation of the ultra-high voltage backbone channel.

在工程建设领域，国网冀北电力针对特高压工程交叉跨越复杂、作业窗口期短等难题，创新采用集控可视化牵张机系统，地面操作人员通过高清大屏即可实时掌控高空导线展放全貌，动态微调牵引力与弧垂参数，成功破解了导线上扬、跳槽、卡线等技术瓶颈。

In the field of power engineering construction, State Grid Hebei Electric Power has innovatively adopted a centralized control visual tensioning machine system to address the complex issues of cross-over in ultra-high voltage projects and the short operation window period. Ground operators can directly monitor the entire process of the conductor extension through high-definition screens, dynamically adjust the tension force and sag parameters, and successfully overcome technical bottlenecks such as conductor uplift, jumping, and entanglement.

在技术研究领域，国网冀北电力依托张北柔直工程建立“虚拟实验室”，在数字世界完整复现工程运行细节，可对柔性直流电网12类复杂工况进行智能化模拟，实现运行特性深度分析、典型故障复现、控制策略验证。

In the field of technical research, State Grid Hebei Electric Power has established a "virtual laboratory" based on the Zhangbei Flexible DC Project. In this digital world, the operational details of the project can be fully replicated. It can conduct intelligent simulations of 12 types of complex conditions for the flexible DC power grid, enabling in-depth analysis of operational characteristics, reproduction of typical faults, and verification of control strategies.

电网建设的加速与科技创新的突破，正转化为实实在在的发展成效。截至“十四五”末，冀北地区风光新能源装机容量突破8000万千瓦，比“十三五”末增长近1.86倍，装机占比达74%。“十四五”时期，冀北电网绿电交易量累计达1001.62亿千瓦时，交易规模连年位居全国前列。

The acceleration of power grid construction and the breakthroughs in technological innovation are translating into tangible development achievements. By the end of the "14th Five-Year Plan" period, the installed capacity of wind and solar power in Hebei North Region exceeded 80 million kilowatts, an increase of nearly 1.86 times compared to the end of the "13th Five-Year Plan". The installed capacity accounted for 74% of the total. During the "14th Five-Year Plan" period, the cumulative volume of green electricity transactions in Hebei North Power Grid reached 100.162 billion kilowatt-hours, and the transaction scale has consistently ranked among the top in the country year after year.

面向“十五五”，国网冀北电力将建成“两纵一横、六落点”的交流特高压布局，通过两项柔直工程将清洁电力向京津冀鲁辐射，推动大规模清洁能源基地交直流电网互联互济格局基本形成。在新能源消纳方面，预计到2030年，冀北地区风光新能源装机占比将达75%以上，新型储能装机达1400万千瓦以上，建成最大负荷20%以上的可调节负荷资源池。

For the "15-18" period, State Grid Hebei Power will establish an "two longitudinal and one horizontal, six key points" layout for AC ultra-high voltage transmission. Through two flexible direct current projects, clean power will be radiated to the Beijing-Tianjin-Hebei region. This will promote the basic formation of a pattern where large-scale clean energy bases are interconnected and mutually supportive through AC and DC power grids. In terms of the consumption of new energy, it is expected that by 2030, the installed capacity of wind and solar power in Hebei region will account for more than 75%, and the installed capacity of new energy storage will exceed 14 million kilowatts. A resource pool with a maximum load adjustment capacity of more than 20% will also be established.
