Abstract

The invention provides a power supply method used for emergency or short-time power supply in local power utilization areas, and relates to the fields of clean energy technology and distributed energy supply. The power supply method comprises the following steps that S1) the power supply state of an external electrical network is monitored in real time, and when the external electrical network is disconnected or fluctuates, a storage battery is used to supply power, and a direct carbon fuel battery is started; S2) after the direct carbon fuel battery is started, the direct carbon fuel battery is used to replace the storage battery to supply power to the local power utilization area; S3) when the external electrical network recovers, the external electrical network is responsible for supplying power to the local power utilization area, the direct carbon fuel cell starts a shutdown program, and needed electrical energy is provided by the external electrical network; and S4) the external electrical network is used to charge the storage battery, and the step S1 is repeated after charging is completed. According to the power supply method, characteristics of the direction carbon fuel cell are combined with those of the storage battery, requirements for the starting performance of a power supply in emergent power utilization can be met, and the requirement of long-term large-power power supply by power users can be also met.

Description

technical field [0001] The invention relates to the field of clean energy technology and distributed energy supply, and in particular provides a power supply method. Background technique [0002] With the deepening of my country's urbanization process, the aggravation of urban environmental problems and the improvement of urban public infrastructure requirements for power equipment. The development of clean and efficient distributed power generation-energy storage integrated devices with Chinese characteristics has become an important way to solve urban energy and environmental problems. [0003] Direct carbon fuel cells (Direct Carbon Fuel Cell, DCFC) can directly use solid carbon-based fuels instead of hydrogen, which is difficult to obtain and store. Through the electrochemical reaction between oxygen in the air and pulverized coal (or other carbon sources such as biomass fuels), the chemical energy in carbon fuels can be directly converted into electrical energy in a cl...
