摘要:
电网作为电力传输的基本途径，是重要的能源基础设施，关系到国民经济命脉和国家能源安全。文章首先介绍了中国交、直流输电电压等级的演变历程和电网技术发展取得的成就，其次从大型能源基地输送需要、分布式能源接入的挑战、节能环保及资源约束、智能化与信息化潮流、用电侧的新要求和电网技术“走出去”等方面分析了当前中国电网技术面临的挑战。最后从大容量远距离输电技术、智能电网、柔性输电、分布式能源接入和配用电及微电网、新形势下的先进调度、设计施工与运维的信息化、节能环保与资源高效利用、设备国产化与标准的国际化等八个方面探讨了现代电网技术的发展方向。 Abstract:As the basic approach of the power transmission, power grid is the critical energy infrastructure related to lifelines of the national economy and national energy security. Firstly, this paper presents the evolution process of AC and DC transmission voltage grade, the development power grid technology. Then the challenge for the current China's power grid technology is analyzed with transmission demand of huge energy base, access challenge of distributed energy sources, energy conservation, environmental protection and resource constraints, trend of intelligence and information technology, new requirement of power demand side and "going-out" of China power grid technology. Finally, high capacity and long distance power transmission, smart grid, flexible power transmission, access, distribution and utilization of distributed energy sources or microgrid, advanced electric power dispatch under new situation, information management of design, operation and maintenance, energy conservation, environmental protection, high efficient utilization of resource, nationalization of electrical equipment and internationalizing of the technical standards are presented to propose the strategies for future power grid development in China.
