摘    要:双回平行输电线路在大电力系统中使用越来越多。为了便于在大电网可靠性评估中计及这种线路各种停运模式的影响,本文运用马尔可夫随机过程理论导出了一种较现有方法更为完整的双回平行输电线路可靠性评估统一模型。该模型可以计及独立停运、相关停运和共同模式停运,并可考虑各种修复方式对双回平行输电线路运行可靠性的影响。算例分析验证了本文提出的模型及算法良好的适应性和有效性。

关 键 词:双回平行输电线路  可靠性  计算模型  电力系统  马尔可夫随机过程理论

Abstract:Two transmission lines in parallel are used more and more in bulk power systems. In order to involve conveniently the kinds of outage modes of these lines in the reliability evaluation of bulk power systems, utilizing the theory of Markov stochastic process, a reliability evaluation unity model for two transmission lines in parallel is deduced in this paper, which is more sophisticated than existing methods. Independent outages, dependent outages and common mode can be included, as well as various effects of repair mode on operation reliability of two transmission lines in parallel can be considered in the model. Example analysis shows that the proposed model and algorithm take on better adaptability and effectiveness.
Keywords:Power system  Two transmission lines in parallel  Reliability  Markov stochastic model  Dependent outages  Common mode outages
