PV/DIESEL HYBRID SYSTEM FOR HIGH ALTITUDE RADIOTELEPHONE

Objective

Provide economic and reliable electric power (1800 W) for a high altitude radio emitter and radio telephone link.

On the top of the Mont Sistron mountain (2610 m) in the Tinee valley a new radio transmitter and radio telephone relais are installed. The power requirement of 1800 W, constant throughout the year, is met by a 7.6 kWp PV system and by a 16 kW (at 2600 m height only 12 kW) Diesel generator (HENNEQUIN, FRANCE). Basic energy supply is by the pv generator (85%), the Diesel generator shall cover the peak and emergency electricity supply (20 starts per year, 250 hours operation, 1250l/year fuel consumption). A data monitoring system (SADO), designed by CNET is available. Special lightning protection is installed.
Alarms and monitoring data are transmitted by radio-telephone to the central control station : intervention is possible within 48 hours (by helicopter).
