以通道运行可用率作为直流输电系统可靠性指标的研究

随着高压直流输电系统的快速发展,传统的可靠性指标在实际的考核应用中暴露出一些问题。通过分析传统能量可用率指标评估存在的问题和缺陷,提出一种基于功率影响的通道运行可用率指标。通过算例解析通道运动可用率指标的算法,并以南方电网公司直流输电系统为例分析新指标的应用效果,从优化检修安排的角度为提高直流输电系统的运行可靠性提供一定的参考信息和决策依据。

Study on Channel Operation Availability as the Reliability Index of HVDC Transmission System

With the rapid development of the HVDC system, the traditional reliability index exists some problems in the actual assess- ment. Through the analysis of the problems and defects of traditional energy available rate, channel operation available index is proposed, which based on the influence of the power. The paper interpret the algorithm of channel operation available index by several examples, then further analysis the application effect on the basis of the historical data of practical HVDC systems in CSG. The result is helpful to provide some reference information on improving the operational reliability of the HVDC system and making decision from the perspective of optimizing maintenance arrangements.
