Abstract
Reliability and efficiency of electrical equipment depends on the quality of electrical energy in distribution networks. The key issue of power quality assurance is the problem of higher harmonics. The problem arose due to the widespread introduction of power electronics as the most effective means of ensuring the required modes of operation of electromechanical and electrotechnological complexes. In this paper the influence of higher harmonics on the power quality is analyzed by means of MATLAB Simulink system, the principle of parallel active filter based on the algorithm of direct current control is considered.
