Abstract
The paper proposes an innovative solution for managing and ensuring high energy efficiency of power supply systems at high non-linear loads (the problem of non-sinusoidal voltage makes up more than 50% of electricity losses). This is realised by maintaining optimal value of reliability indicators and high quality of power supply. The validation is carried out using analyses and tests of the quality of electromagnetic compatibility (EMC) for an increased number of powered frequency converters. It has been proven that the effective use and reduction of energy consumption can be achieved thanks to the unique technological features of the employed electrical devices. This enables a normal operation of the system with decreased power and adequate control of energy processes. The problem of predicting power losses under changing conditions in a decentralised electrical network has been solved based on the theory of electromagnetic compatibility. The influence of the mains mode parameters and the indices of instantaneous distortion of current and voltage waveforms caused by the operation of converters on the resonance phenomena in power supply systems were investigated. Recommendations were developed for the selection of proper parameters of compensators for 6–10 kV and 0.4–0.66 kV circuits based on the analysis of the optimisation problem when minimising active power losses. The results of our findings may aid parties involved in designing and maintaining power networks in various applications, such as mines, etc. Decisions to improve the energy efficiency of electrical networks fully correspond to the Concept of ensuring energy security of Ukraine.
