|System||Photovoltaic/wind hybrid with battery bank and diesel generator back-up.|
|Location||Lake Bonney, Antarctica (77 42 52 S 162 27 51.0 E
Lake Bonney is located near the head of the Taylor Valley in Antarctica’s Dry Valleys.
|Description||The camps permanent facilities include a Jamesway with
heated kitchen/living space, and three small Laboratories. The
battery/inverter system provides 4 kW of 120 VAC power to all four
Lake Bonney’s power system consists of two manual tracking solar arrays, each supplying 680 watts and a 360-Watt wind generator. The power is stored in a 600-amp hour battery bank that is backed up by diesel generators. The solar power is processed using a maximum power point tracking (MPPT) charge controller, taking advantage of cold ambient temperatures and resulting higher voltage from the PV panels. DC power from the batteries is converted to AC by a 4000-watt inverter/charger that supplies 120VAC power to the camp buildings and labs. The two diesel generators can be manually started as required, to charge batteries and power the camp simultaneously. Real time data is taken measuring solar and wind input, AC output, and battery voltage. The data is logged on site and sent to McMurdo via free wave Ethernet. For camp users, a battery system monitor in the Jamesway monitors the Battery voltage, net amperage and the % battery capacity. This system monitoring enables users to decide when to make adjustments to solar panels, loads or add generator power as necessary.
