Спосіб компенсації взаємовпливу неоднорідних електричних мереж

Abstract

A method for compensation of mutual influence of inhomogeneous electric networks comprises measurement of voltage in electric network controlled nodes, determination of transient and system-wide losses of electric power in power transmission lines, determination of compensating electromotive force; selection of parameters of a cross-transformer being mounted, determination of system mode parameters to load changing. According to the method a complex inhomogeneous factor is determined; also sensitivity of complex inhomogeneous factor to a mounting point, a point for transformer mounting are determined, the cross-transformer is installed. One determines capacities neutral zone in nodes, a neutral zone of power losses distribution coefficients in the circuit branches, complex value of compensating electromotive force at buses of controlled substation are determined, checking calculation of complex inhomogeneous factor, real influence of the cross transformer to total power losses in electric system and losses caused by transit flows are determined.
