摘要
对电气元件等效二状态模型进行优化,提出了计及计划检修状态的元件等效三状态模型,使之符合柔性直流输电系统实际运行情况。以广东龙门换流站为例,通过等效三状态模型计算柔直换流站电气主接线中各元件的可靠性参数,使用分区简化方法计算各分区的可靠性参数。在此基础上,利用目标导向(GO)法和动态贝叶斯网络相结合的方法建立了电气主接线的可靠性模型,求解柔直换流站可用度、不可用度以及计划检修概率的时变曲线,验证了所提模型和方法对柔性换流站电气主接线可靠性评估的可行性与有效性。
The equivalent two-state model of electrical components is optimized,and the equivalent threestate model of components considering scheduled maintenance state is proposed to conform to the actual operation of flexible direct current(DC) transmission system. Taking Longmen converter station in Guangdong as an example,the reliability parameters of each component in the main electrical connection of the converter station are calculated by the equivalent three-state model,and the reliability parameters of each partition are calculated by the simplified partition method. On this basis,the reliability model of electrical main connection is built by combining goal oriented(GO) method and dynamic Bayesian network,and the time-varying curves of availability,inavailability and scheduled maintenance probability of voltage source converter-DC(VSC-DC) converter station are solved. The feasibility and effectiveness of the proposed model and method for reliability evaluation of electrical main connection of VSC-DC converter station are verified.
