Design, simulation and implementation of an intelligent power management system for a battery supported power distribution system

摘要

In this paper, a practical Fuzzy controlled power distribution system (PDS) for supplying telecommunication sites, mobile and satellite Base stations is designed, simulated and experimentally tested. The system consists of a fuzzy controlled power management system (FCPMS), several paralleled switching mode rectifiers (SMR), batteries and other appropriate equipments. The SMR units supply load and charge batteries in normal conditions and batteries should supply the load in an AC power outage via an online control with FCPMS. The FCPMS performs two intelligent operations. Firstly provides an online current sharing capability for paralleled SMR units during their normal condition of supplying load and charging batteries. Secondly, maintains a fast and stable charge for battery set while battery voltage and temperature is kept safe and stable during the charge process using a fuzzy based algorithm. The simulation results confirm experimental responses.
