Gapon D. Methods and tools of improving the quality of operation of automatic power system load shedding in emergency mode

The object of study - the process of performing automatic load shedding in power system in emergency situations involving transient frequency. The aim - to develop methods and computer hardware automatic load shedding, which can react quickly and reliably if distortion of input signal, characteristic for different objects energy systems. Methods. When conducting research used theory methods of digital signal processing, measurement theory, mathematical statistics and logic algebra. Theoretical and practical results - increased speed devices discharge, reduced likelihood of false positives. Novelty - the first time the methods of measuring frequency, speed of change and the level of distortion of input signal, is proposed to use interval estimates of frequency and speed of change to eliminate false positives. The degree of implementation: SE "NPC" UE "(Kyiv), National Technical University" KPI "(Kharkiv). Scope: electricity.
