Research of Ice-melting Path Selection Based on Graph Theory
Icing of overhead power lines is a serious problem for electric utilities. Among various deicing approaches, short circuit based de-icing is one of the most frequently used approaches. Whereas, formation of short circuit based de-icing scheme is not a simple task since transmission lines are tripped and system topology varies notably in ice storm. Based on thorough investigation of pre-established de-icing schemes, rules to set up de-icing schemes are concluded. An expert system combining the power of graph theory has been developed in the paper to enumerate all ice-melting paths. Based on the ice-melting paths enumerated by the system, dispatch staffs can form optimal de-icing scheme easily.
