摘要
文中主要针对影响输电线路运行可靠性的外部因素并结合输电线路负载水平,建立基于马尔科夫过程的输电线路运行可靠性评估模型。在建立的概率论与数理统计评估模型的基础上,通过PSCAD/EMTDC仿真分析可控串连补偿装置在0、10%、30%串补条件下,对应的输电线路运行风险为0.8538、0.5138、0.0918,结果表明,可控串联补偿装置可以有效提高输电线路的运行可靠性。
This paper focuses on the external factors that affect the reliability of transmission lines and the load level of transmission lines,and establishes a Markov process-based reliability evaluation model for transmission lines.Based on the established probability theory and mathematical statistical evaluation model,PSCAD/EMTDC simulation analysis of the controllable series compensation device under 0、10%、30%series compensation conditions,the corresponding transmission line operation risk is 0.8538、0.5138、0.0918,the results show that the controllable series compensation device can effectively improve the operation reliability of the transmission line.
