摘要
通过国外1998年—2002年和国内2001年—2005年高压直流输电工程运行可靠性统计资料的分析比较,归纳出影响其可靠性水平的主要因素及其变化趋势。利用这些结果,结合国外高压直流输电工程运行资料,对单12脉接线方式和双12脉接线方式直流输电系统的可靠性进行了综合分析,为高压直流输电系统可靠性的研究、运行管理提供一定的参考信息和决策依据。
The statistical data about the operation reliability indices of the nationalHVDC transmission projects during the years of 200l to 2005 and the historical data abroad from 1998 to 2002 are summarized. Through analyzing and comparing among reliability indices of these HVDC projects, the main factors influencing reliabilities of systems and the tendencies of these factors are clarified. Using the resulting information including HVDC projects abroad, the paper then makes a comparison among reliability indices of HVDC projects with two converters per pole and single converter per pole, respectively. The statistical analysis and conclusions are capable of being used as reference to decision making for the operating, planning and management of HVDC projects.
