直流 (DC) 链路以长距离传输和异步互连的形式在世界各地得到越来越多的使用。包含直流母线的复合发电和输电系统的系统可靠性研究涉及直流输电线路可靠性的建模和评估以及直流母线构成组成部分的整个复合系统研究的性能。本文阐述了一种使用意外事件枚举方法进行直流系统可靠性分析的技术。该系统可靠性分析的一个关键要素是从单线图创建可靠性图。开发了一种数字计算机程序来评估直流链路的故障概率、故障频率以及可能性能水平的平均持续时间。该过程和程序在模型直流系统上进行了测试，结果用于说明所提出的技术。
Direct current (DC) links are finding increasing use throughout the world in the form of long-distance transmission and asynchronous interconnections. System reliability studies of a composite generation and transmission system containing a DC link involve modelling and evaluation of the reliability of the DC transmission line and performance of an overall composite system study with the DC link forming an integral part. The paper illustrates a technique for DC system reliability analysis using the contingency enumeration approach. A key element in this system reliability analysis is the creation of the reliability diagram from the single line diagram. A digital computer program was developed to evaluate the probability of failure, frequency of failure, and the mean duration of the possible performance levels for a DC link. The procedure and program were tested on a model DC system, and the results are presented to illustrate a proposed technique.
