Abstract
Modules for calculating and increasing power factor and efficiency, which characterizes efficient energy use, as well as coefficients of voltage nonsinusoidality and current distortion, which characterizing the quality of electricity, and a reversible module of total power and its active and reactive components, are proposed for implementation in the MATLAB environment. By means of the proposed modules, an investigation of electrical complex with the ability to discharge electrical networks and maintain consumed voltage at a given level was performed. The measurement modules are constructed on elements taken from the Library Browser and are compatible with MATLAB. Block structures were examined in order to calculate the energy efficiency of the complex. The process of energy exchange via a direct-current link between the electric drives was analyzed. One of the drives operated as an energy consumer, while the other operated as a generator; herewith, the energy consumption of the electric drives decreased. The use of voltage boosters with a directcurrent link based on static converters of electric energy allows the energy efficiency of the electrical complex to be increased significantly.
