摘要:

为准确评估中国昆柳龙混合直流工程送端换流站电气主接线的可靠性,建立了昆北换流站电气主接线中静态元件、动态元件和附属元件的等效二状态模型。以减少计算复杂度为目的,针对元件的故障后果及位置将送端换流站进行了分区简化。将GO法与模糊动态贝叶斯网络相结合建立了系统的可靠性模型。所构建的模型能直观反映系统可靠性的时序变化过程,并可利用后验概率进行电气主接线的脆弱性分析。仿真结果的分析证明了所提模型和方法的可行性与有效性。

Abstract:

In order to accurately evaluate the reliability of the main electrical connection for the sending-end converter station for Kunliulong hybrid DC project of China, the equivalent two-state models of static components, dynamic components and auxiliary components in the main electrical connection of Kunbei converter station are built. In order to reduce the computational complexity, the sending-end converter station is partitioned according to the fault consequence and location of the components. Then, the GO method and fuzzy dynamic Bayesian network are combined to built the reliability model of the system. The proposed model can directly reflect the time-sequential change process of the system reliability, and can use the posterior probability to analyze the vulnerability of the main electrical connection. The feasibility and effectiveness of the proposed model and method are proven through the analysis of simulation results.
