METHOD DETERMINING PARAMETERS OF COMPLEX RESISTANCE OF ELECTRIC NETWORK FROM POINT OF CONNECTION OF POWER TRANSFORMER TO POINT WITH INFINITE POWER OF SHORT-CIRCUIT

摘要

FIELD: electric measurement technology, experimental measurements. SUBSTANCE: method makes it possible to determine parameters of electric network in experimental- computation way without interruption of power supply. Measurement of electric parameters with various transformation ratios of reference element-power transformer is conducted in agreement with method in electric network composed of reference and measured sections connected in series. Parameters of complex resistance of section of network from point of connection of power transformer to point with infinite power of short-circuit are found by solution of equations of electric network. Number of equations is determined by number of established transformation ratios of reference power transformer and more accurate values of parameters of complex resistance is obtained as average computed by results of solution of system of difference equations. EFFECT: improved authenticity of method. 2 dwga
