摘要: |
通过分析智能变电站监控系统的工作机制,提出运用动态贝叶斯网络评估其可靠性。首先,将监控系统的功能划分为三类,并建立了相应的功能可靠性框图。其次,在建立的功能可靠性框图的基础上,构建了监控系统动态贝叶斯网络模型及其求解方法。最后,以算例验证了所提方法的有效性。结果表明,该方法能较好地描述监控系统的动态特性,为系统的优化配置、故障诊断提供参考。 |

Abstract: |
Based on analysis of operating mechanism of smart Substation Supervision and Control System (SSCS), Dynamic Bayesian Network (DBN) is introduced to evaluate the reliability of SSCS. First, the function of SSCS is divided to three types and the corresponding functional Reliability Block Diagrams (RBD) are established. Secondly, the DBN model and its solution of SSCS are implemented based on the functional RBD. Finally, a study case is presented to demonstrate the effectiveness of the proposed method. The results show that dynamic characteristics of SSCS could be well described by DBN and hence provide reference for the system configuration optimization and fault diagnosis.
