WindKinetic hybrid off-grid power trailer for a WiMax emergency repeater in a copper mine in Aktogay, Kazakhstan
The trailer supplies continuous and reliable electrical energy to the emergency communication and video surveillance system in the Aktogay mine, in an extremely challenging environment with temperatures from -40°C to +50°C, dust, and mud.
Windkinetic designed and engineered the system to operate in these harsh conditions without downtime.
The system consists of a customized off-road trailer with a special structure and a telescopic tower. The system includes one Windkinetic Magellano 500 W wind turbine and 2 solar arrays (1000 W total). A diesel generator is installed as a back-up.
The wind turbine is on top of a stainless steel telescopic mast, where Siemens Wimax devices are also installed. The solar panels are mounted on the side and on the top of the trailer structure, to be easily and safely oriented.
The trailer chassis has 2 separated compartments. All the charging electronics are inside the first one, as well as the battery bank and the telecom devices. The genset, diesel heater and fuel tank are in the second compartment.
The compartments are thermally controlled both at low temperatures by the diesel heater and at high temperatures by cooling fans.
The entire system can be installed and be operational in less than 1 hour.
The evaluation of the state of health of the system is performed by a remote monitoring and control system.
This power trailer system is designed to minimize the downtime and is intended to be used in extremely demanding applications, such as telecommunication, mining, oil&gas, disaster relief and everywhere there is a need of a reliable yet easy deployable source of power.
