Intelligent function associated with a colored Petri net (CPN) inference model is developed for service restoration of power system of semiconductor industry (SI). The CPN models for a four-way switch and other power components are proposed to implement proper restoration plan after the faulted location has been identified and isolated. The unfaulted but out of service areas are restored efficiently...
An operational strategy for secondary power system restoration using grey relational analysis (GRA) is presented. The restoration scheme can be divided into three steps involving fault section determination, recovering process and voltage correction process. Three GRAs are incorporated to design the overall restoration scheme. The first GRA uses the network-switching status to identify the fault....
