METHOD FOR DETERMINING INSTANT VALUES OF PARAMETERS (OF CURRENTS AND VOLTAGES) OF DIRECT AND REVERSE SEQUENCES

摘要

FIELD: electrical engineering.SUBSTANCE: field of application: electrical engineering. According to the method, the currents and voltages of direct sequences are determined as half the sum of the parameter of one phase without a zero component with a reduced value in √3 times the difference in the parameters of the other two phases, shifted in time by a quarter of the period of the network frequency beyond the above phase. And the currents and negative sequence voltages are defined as half the difference of these quantities.EFFECT: technical result is to ensure the filtration of aperiodic components.1 cl, 1 dwg
