Hybrid Power Systems for Remote Sites - Solar, Wind and Mini Diesel

This paper describes a hybrid power supply system for remote sites, ERICSSON SUNWIND, consisting of solar, wind and mini diesel generators. As the system uses both solar and wind generators the particular advantages of this combination are discussed. A highly reliable wind generator of vertical axis type will be described. It is virtually maintenancefree and equipped with unique lightning and overspeed protections. Also it is equipped with a microprocessor-based control system for output power optimization, which will be described in another paper presented at this INTELEC Conference. The system includes two reserve energy sources, i.e. the station battery and the mini diesel generator set. The minidiesel which uses DC-generation will be described together with its control equipment. Its most important characteristics are the simple auxiliary system and the start up safety.
