电网故障模型中贝叶斯网络和DS证据理论的应用

Application of the Bayesian network and the DS evidence theory in power grid failure model

由于电网的复杂性和多变性,导致电网故障中存在信息不确定性问题,这就需要依靠贝叶斯网络和DS证据理论的自动生成方法。文章主要描述了这两种方法的原理,讨论了贝叶斯网络和DS证据理论在电网故障模型领域应用的可能方式和情况,并运用一些实例证明了这种方法的可靠性。

The complexity and variability of the power grid led to the problem of information uncertainty in power grid failures,which needs to rely on the automatic generation method of Bayesian networks and DS evidence theory.This paper mainly describes the principles of these two methods,discusses the possible way and situations of the application of the two methods in power failure model field,and demonstrates the reliability of the methods by some actual examples.
