【摘要】：通过对TCSC结构和故障模式分析,构建了TCSC及其子模块的可靠性框图,计及部件冗余配置讨论了子模块可靠性;深入分析了TCSC的电抗随电流而变化的运行特性,基于此提出了一种计及TCSC视在电抗约束的线路可靠性模型;根据实时运行条件下故障率参数的时变特性,应用马尔可夫理论推导了TCSC核心部件以及整个线路的状态概率计算公式,并基于运行风险理论建立了条件相关的故障率模型,该模型定量考虑了负荷随机波动、元件老化以及气温变化对元件可靠性的影响。通过对RBTS测试系统可靠性的计算分析,验证了所提模型的有效性和正确性。
[Abstract]:Based on the analysis of TCSC structure and fault mode, the reliability block diagram of TCSC and its sub-modules is constructed, and the reliability of sub-modules is discussed considering the redundant configuration of components, and the operating characteristics of TCSC's reactance varying with current are analyzed in depth. Based on this, a line reliability model with TCSC apparent reactance constraints is proposed, and the time-varying characteristics of failure rate parameters under real-time operation conditions are analyzed. The state probability formula of TCSC core components and the whole line is derived by using Markov theory. A conditional dependent failure rate model is established based on the operational risk theory. The stochastic load fluctuation is quantitatively considered in the model. The effect of element aging and temperature change on component reliability. The validity and correctness of the proposed model are verified by calculating and analyzing the reliability of the RBTS test system.
