Examples

And selecting Daqing by site reference, and selecting a photovoltaic system and fuel cell system power supply design scheme according to the scheme. The electrical appliances used were as follows, see table 1,

TABLE 1

According to the table 1, the daily life electricity consumption of the multifunctional comprehensive energy cabin is estimated to be 11.9 degrees.

According to the statistics of power generation of a system power generation system, the photovoltaic and lithium battery are matched for use, so that the power consumption of daily life in the cabin can be basically met, and the lithium battery can be ensured to be in a full-capacity state every day.

The lithium battery can store 30 degrees of electricity.

When the fuel cell system cannot work, the lithium battery supplies power, air is used for heating, the daily electric quantity of the equipment in the cabin is 17.5kWh, and the lithium battery can continue to supply power for 1.5 days. The lithium battery and the fuel cell power generation system can be used for the normal work of the electric equipment in the cabin for 14.5 to 16.5 days. If the photovoltaic can also be for lithium battery charging every day, the power supply cycle still has certain increase, in addition, when the electric quantity is surplus, can set up the wiring mouth on the lithium cell and supply power to outside.
