An unknown fault identification method based on PSO-SVDD in the IoT environment
When a new fault occurs, how to determine whether the new fault is a known fault or an unknown fault outside the fault pattern base. If a new unknown fault is identified, adding the unknown fault to the fault pattern base for adaptive updating the fault diagnosis model has become a new problem in th...

If a new unknown fault is identified, adding the unknown fault to the fault pattern base for adaptive updating the fault diagnosis model has become a new problem in the field of fault diagnosis. In order to solve this problem, we take Box transformer substation (BTS) widely used in power distribution equipment as an example, propose an unknown fault identification method.
