ANALYSIS OF METHODS FOR CONTROLLING INPUT SIGNAL PARAMETERS IN ADAPTIVE MICROPROCESSOR CURRENT PROTECTION OF TRANSMISSION LINE

Abstract

The paper considers and analyzes various methods for determination existing values of input phase currents in an adaptive microprocessor current protection of transmission lines. While using a method of a calculative experiment dependences for changing relative existing values of currents determined by various approaches. Every method has been studied from the point of its positive protection operation and stability in determination of short circuit mode, in other words from the point of realization of an adaptivity principle.
