The article deals with an improved method of optimization of the usage of electric energy in the object of telecommunications provided constant and variable non-linear load. The mentioned method deals with contradictions, which stands in the need of increasing fundamental harmonic, which causes problems in the practical implementation and reduction of the current with high harmonics of nonlinear variable load. It was established that a weighty part of telecommunication equipment is a non-linear load, operation of which leads to significant network distortions. The classification of negative factors, associated with the emergence of higher harmonics of currents and voltages and methods of their suppression was given. To optimize the transmission of electricity in the nonlinear load it was proposed to use a special power supply, which further need to be enabled in electrical circuit and then it provides compensation of the higher harmonics of nonlinear current. Scheme solutions of optimizers of transmission of electric energy to the non-linear load with constant and variable parameters were presented. The structure and algorithm of the method of optimization of electricity, which deals with determination of the amplitude and phase of harmonics of non-linear load by the method of fast conversion of Fourier and formation of signal control by the active filter of harmonics, were determined. Conclusion. Due to the application of the method of optimization of transmission and usage of electric energy, which takes into account changes in nonlinear load and harmonic current parameters, the quality of electric energy usage is increased and the nominal mode of operation of telecommunication objects is provided.
