Regulating steady-state voltage deviation using fuzzy logic [PDF]

PRZEGLĄD ELEKTROTECHNICZNY
A model of regulation of steady voltage deviation using fuzzy logic was proposed for the problem of normalizing voltage quality in the network. On the basis of simulation, the effectiveness of the proposed algorithms is shown. The control algorithm based on fuzzy logic is considered as an alternative to the transition from analogue control to the ...
