Компенсація взаємовпливу неоднорідних електричних мереж з використанням лінійних регуляторів

Abstract

The thesis is devoted to the solution of the problem of improving the operating efficiency of the electric grids of the energy supply companies by means of the optimal control of power flows, phase-shifting angles and voltages in the electric grids using transformers with top-charging and cross-transformers. The dependence of power losses, which are caused by mutual and transit flows between the main electric grids and distribution grids, on the change of transformation ratio of the cross-transformer located in the electric distribution grid has been determined. The method to determine the reasonable joining place for the cross-transformer in the electric distribution grid and the optimal value of the cross-transformer angle at which the voltage vector is moved has been developed. This method is based on the compensation of the nonuniformity of the electric grids working in parallel.
