| 摘 要： | 针对电网发生故障时，故障信息不完整或不确定，难以得到正确结论，以及贝叶斯理论虽在解决不完整数据上具有优势但不能大规模建模的问题，定义了贝叶斯Petri网(BPN)，提出了基于BPN方法的电网故障诊断算法。利用某电网对该算法进行验证，结果表明，该算法能够快速准确诊断故障元件，提高了诊断的容错性。

| Abstract: | Focused that fault information lost or distorted lead to get inaccurate conclusion when power net is in fault,and Bayesian theory is not able to resolve the problem of large scale modeling though solving incomplete data effectively,the paper defines Bayesian Petri Net(BPN).And then it proposes a fault diagnosis algorithm of power net based on BPN.The result of verification of the algorithm through some power net proves that the algorithm is able to locate the fault area and identify fault unit accurately an... |
