Abstract

The paper considers the frequency load shedding of an electric power system. The objective of this paper is to enhance the structure and algorithms of frequency load shedding-1 (AUFLS-1) using cutting-edge technologies, namely Wide Area Measurement System. We model the operation of the system of complex power supply when various emergencies in the Power Factory software occur. We aim at revealing the fact of the voltage corner reaction on the emergency occurrence and elaborating the algorithm of detecting the emergency by speed of voltage corner change. The result and novelty of this research is that we propose how to upgrade the system AUFLS-1 by introducing the additional starting block reacting to the speed of the voltage corner change which increases the speed of AUFLS-1 system operation. As a result the system AUFLS-1 starts up not only by achieving “frequency” set point but also by analyzing the speed of voltage corner change.
