对提高电网输电能力的认识与思考

Thoughts of improving the transmission capacity of power grid

通过分析影响我国电网输电能力的主要因素及受限原因,和对国内、外提高电网输电能力先进经验,尤其是电网新技术、新材料、新方法应用的研究,提出了为提高电网输电能力而应采用的实用化技术和措施,主要包括:紧凑型输电、FACTS技术、动态增容、采用耐热铝合金导线、高压直流输电、加强电网建设等。

Analyzes the main factors and limited reasons of affecting the transmission capacity for power grid, and discusses the domestic and overseas advanced experiences improving transmission capacity of power grid, especially studies the advanced techniques, new materials and advanced methods, bring forwards the practicable technic measures for improving transmission capacity of power grid including： compact transmission line, FACTS, dynamic capacity-increase, using heat-resistant aluminum alloy line, High Voltage Direct Current Transmission （HVDC） and strengthening the power grid construction, etc.
