Abstract

This paper is to introduce a more effective and flexible restoration algorithm composed to the fault preventing and restoring system now in use. This was possible by considering the changes that can occur by the proper or the improper run of the Feeder, which the power system restoration method now using didn't consider. The new algorithm uses the method minimizing the loss with respect to the load changes occuring when the power system is restored, rather than just simply following the SOP that is only composed of a single Feeder On/off combination. This can present the more effective power system running method for the safer subway running and passenger transport, by giving the system operator the chance to choose between the SOP and the minimum loss method.
