Communication base stations distribute broadly and the power supply environment is complex. Due to these reasons, there are plenty of places which cannot connect the mains, connect the extremely unstable mains or keep the expensive costs of connection. For these area, it is very common to use hybrid power system to provide normal power supply.
Wind-solar-diesel hybrid power system is a kind of integrated energy development power supply system. The system is a combination of diesel generator, solar panels, wind turbines, system controller, storage battery and inverter, etc. It brings together the output electrical energy of wind turbines and solar photovoltaic cell array. The power supply of diesel generator is charged to storage battery as supplement.
If it is sunny or windy, the power supply of system and the electricity of storage battery will be provided by solar and wind. If severe weather conditions persist, with lack of wind, solar and the power shortage of storage battery, the system will start diesel generator quickly to supply power and charge the storage battery after the genset self-starting module detects the starting condition of battery voltage.
Wind-solar-diesel hybrid power system can reduce the dependence of the system on weather and greatly improve the system reliability.
