Chinese Abstract

為了計算和分析輸電線路對大電網可靠性評估的影響,提出一種計及雙回平行輸電線路獨立停運、共同模式停運和相關停運的大電網可靠性評佑模型和算法。計及共同模式停運和相關停運時,雙回平行輸電線路的兩回線實際上是一個具有多個狀態的元件。提出的算法可以在形成可靠性指標時,同時計算這種多狀態元件造成系統失效狀態下獨立停運、共同模式停運和相關停運的概率和頻率,減少了計算複雜性。通過對RBTS系統、IEEE-RTS96區域A系統和一個實際電力系統進行的可靠性計算分析,驗證了提出的算法的正確性和有效性。

English Abstract

In order to calculate and analyze the effect of two transmission lines in parallel on the reliability evaluation of bulk power system, a model including independent outage, common mode outage and dependent outage of these lines is deduced and a new algorithm corresponding to the model is presented. Two transmission lines in parallel including common mode outages and dependent outages can be really simulated as a multi-state component. While reliability indices are calculated, the probability and frequency of independent outage, common mode outage and dependent outage of a system failure state can be calculated at the same time, and computation complexity is reduced. The proposed model and algorithm are applied to the RBTS system, IEEE One Area RTS96 system and a real power system for reliability computation and analysis. Results show that the new algorithm is credible and validity.
