Study of the possibilities for optimization of reactive power according to the criterion "electric power quality" in the power supply system of a port complex

The paper presents an opportunity to optimize the reactive powers in the power supply system (PSS) of the port complex of Burgas. Based on the general energy characteristic of the object and synthesized theoretical statement, in the conditions of asymmetric and non-sinusoidal loading. Instrumental measurements and analyzes were performed, with the help of which quantitative ratios for the different partial losses were established and finally the total losses of active power were determined. It was found that the compensation of reactive loads in the conditions of deteriorated electric energy (EE) quality does not ensure good results. In this regard, a significantly better and more efficient technical solution developed according to the criterion of "high quality EE" is proposed. The practical implementation of the proposal guarantees the achievement of energy efficiency, significant EE savings and a payback period of the facilities within (1.8 ÷ 3.1) years.
