Abstract

Ways of searching for optimal ways to improve the quality of electric energy in electric networks with dispersed unbalanced loads using zero-sequence current filters are considered, which take into account the possibility of ensuring the desired performance with minimal cost and taking into account the peculiarities of operation in emergency network conditions and ensuring electrical safety of consumers. Corresponding calculations were carried out using simulation modeling. References 6, figures 4.

Key words: power quality, voltage unbalance, zero-sequence current filter, emergency modes, safety.
