The aim of the research presented in the article is to develop methods and means for integrated modeling of compact expanded capacity power lines. Algorithms for determining modes of electrical energy systems were used based on phase coordinates based on application of elements models in form of lacelike equivalent networks with fully-meshed topology. These models and methods were implemented in Fazonord-APC software application, ensuring modeling of EES sta-tionary modes, and determining strengths of electromagnetic fields generated by power lines of different design. We demonstrate results of modes and electromagnetic fields modeling on routes of 220 kV compact overhead power supply lines (COPL) with horizontal positioning of wires. For the purpose of comparison, similar calculations were performed for a typical overhead power line (TOPL). The modeling results allowed to formulate the following conclusions: when overall sections of COPL and TOPL are equal, the losses of active power in compact OPL are significantly lower; thus, when transmitted power is 375 MW, the losses in COPL are reduced by 45% compared to a typical 220 kV OPL; at compact OPL receiver end a lower unsymmetry is observed; COPL ensure better electromagnetic safety conditions; electrical field strength at a height of 1.8 m for COPL axis is less than a similar index for TOPL by approximately 1.5 times; magnetic field in the same point is reduced to 60%.
