Process simulation modeling for sequence switching strategy in substations

Automatic sequence switching has been an important pursuit in the field of substation automation. This paper presents a software process simulation modeling representation and method for sequence switching strategy in substation. It starts with a presentation of sequence switching problem, then, suggests a component-driven pattern recognition model of a substation switch network organized in a logic relationships structure of constraint objects, and reachability of Petri nets suitable for constraint satisfaction. An intelligent optimal sequence switching strategy and component-driven knowledge representations of sequence switching are presented. The software process simulation modeling method provides a platform for further research in terms of intelligent decisionmaking of switching processes.
