摘要
直流输电系统的可靠性水平已成为影响整个电力系统可靠性的重要因素。文章从强迫停运次数、强迫能量不可用率、计划能量不可用率、能量利用率这4个方面,分析了2003年以来国家电网公司直流输电系统的可靠性。直流输电系统的各个可靠性指标相互影响,建立科学合理的可靠性评价体系,可实现电网资产效益最大化。对比国内外直流输电系统的可靠性指标,分析得出国家电网公司直流输电系统可靠性水平位居世界前列。
Reliability level of HVDC power transmission systems becomes an important factor impacting entire power grid. The author analyzes the reliability of HVDC power transmission systems owned by State Grid Corp. of China since 2003 in respect of forced outage times, forced energy unavailability, scheduled energy unavailability and energy utilization efficiency. Different reliability indices of HVDC power transmission system interact one another, thus to implement the maximization of property benefit of the power grid it is necessary to build a scientific and reasonable reliability evaluation system. The results of analysis on reliability indices of HVDC power transmission systems home and abroad show that the reliability level of HVDC power transmission systems owned by State Power Grid Corp. of China is in the forefront in the world.
