Telephone network based on IMS technology has been widely applied in
power production and dispatching communication, especially in distributed
power stations. Analysis and positioning failure of IMS network is arduous,
because it’s dependent on IP data communication network. In this paper,
we first introduced IMS switching network architecture and distributed gen-
eration communication network architecture, analyzed and summarized all
kinds of network malfunction. Combining typical IMS network fault con-
nection relations, we introduced an improved Petri net fault handling model
and reasoning method. The diagnosis and positioning results could reflect
the defects of equipment logic functions. This method on fault diagnosis
and location of substation network has been proved to be effective through
practical application.
