Abstract:
1. A method for managing power at an unmanned remote site having at least one battery and at least one generator, said method comprising the steps of: determining whether site temperature at the remote site meets a predetermined upper limit for initiating battery discharging; determining whether battery charge of the at least one battery at the remote site meets a predetermined lower limit for initiating battery discharging; initiating discharge of the at least one battery to power the remote site if commercial power is unavailable at the remote site, the site temperature is below the predetermined upper limit for initiating battery discharging, and the battery charge is above the predetermined lower limit for initiating battery discharging; initiating operation of the at least one generator to power the remote site if commercial power is unavailable at the remote site and at least one of the site temperature is not below the predetermined upper limit for battery discharging and the battery charge is not above the predetermined lower limit for initiating battery discharging; transferring load from the at least one generator to the at least one battery to power the remote site if the at least one generator is operating, the site temperature is below the predetermined upper limit, and the battery charge is at full charge; and transferring load to commercial power if commercial power becomes available at the remote site when one of the at least one battery and the at least one generator is powering the remote site.
