Fault detection method based on intelligent power distribution environment

The invention discloses a fault detection method based on an intelligent power distribution environment. The problem of singularity-free cloud terminal network fault detection of a singularity-free cloud terminal network structure time-delay control system is researched. Considering the state of interval variable predication on an intelligent power grid, a cloud model network structure time-delay singularity-free cloud terminal network fault predication filter is designed. A perception recognizing method that a non-deterministic non-linear structure time-delay feedback filter structure comprises a cloud theory model used for predicating the relevant information of the intelligent power grid is used. Based on the singularity-free cloud terminal network structure time-delay control system filter method, dependence sufficient conditions existing in the singularity-free cloud terminal network fault detection filter are executed, and an iterative method for designing the system weight of the filter is provided.
