摘要:

在中国经济发展和能源分布不平衡的情况下,直流输电在实现节能减排和资源优化配置中发挥着越来越重要的作用。为不断提高直流输电系统的运行可靠性,全面掌握国家电网公司直流输电系统运行情况,以国家电网公司经营区域内的特高压直流、高压直流及背靠背直流输电系统为研究对象,以直流输电系统实际运行数据为基础,对强迫停运情况进行统计分析。并从极端天气、设备故障、外力破坏等角度展开讨论,结合典型故障案例说明国家电网公司直流输电系统面临的安全形势,分析现有系统的薄弱环节并提出相关建议。

Abstract:

Under the condition of unbalanced economic progress and geographical distribution of natural resources in China, high voltage direct current (HVDC) transmission is playing a more and more important role in energy saving, emission reduction, and optimization of resource allocation. To steadily improve the reliability of the operating HVDC systems and provide a full view of the operating HVDC conditions in State Grid Corporation of China (SGCC), this paper takes the HVDC systems, ultra high voltage direct current (UHVDC) systems and back-to-back HVDC systems as the research objects, and a statistical analysis is made of the forced outages using the yearly operation data. An assessment is made of the systems’ operating conditions from the perspective of the extreme weather, equipment fault, and external damages. By referring to typical case studies of faults, the security situation the SGCC is in is made clear. The weak links in the systems available are analyzed and relevant suggestions are made.
