摘要
提出了基于分离模型的考虑独立停运、共因停运和相关停运的双回平行输电线路可靠性评估模型,解决了传统的评估模型计算量大等缺点,在电力系统中双回路使用越来越多的情况下,使可靠性评估计及其他停运模型的影响成为可能。该模型可以很容易地计及不同的停运模型,采用交集的概念计算系统的失效概率和等效故障率,并分析不同停运模型对系统故障率的影响,算例分析验证了分离模型的有效性。
Based on the individual model, a reliability evaluation model for parallel two-circuit transmission lines is proposed which considers independent outage, common cause outage, and dependent outage. The model overcomes the shortcomings of traditional evaluation models such as large amount of calculation, and enables reliability evaluation to involve the influences of other outage models. The model uses the concept of intersection to calculate the system failure probability and equivalent failure rate, and analyzes the effect of different outage models on system failure rate. Calculation example shows the individual model effective.
