Abstract

The invention provides a zero-carbon-emission hydropower station comprehensive energy system. The system is characterized by comprising a hydrogen production device, a hydropower station power generation system, a hydrogen storage system and a hydrogen fuel cell, wherein an alternating current output end of the hydropower station power generation system is electrically connected with a power inputend of the hydrogen production device to supply power, hydrogen generated by the hydrogen production device is outputted to the hydrogen storage system, the hydrogen stored in the hydrogen storage system is outputted to the hydrogen fuel cell to be used as a cell raw material, and the direct current generated by the hydrogen fuel is outputted to the hydropower station system to supply power to direct current loads in the hydropower station system. The system is advantaged in that the hydrogen energy is used as an energy storage and energy conversion medium, energy supply and zero carbon emission in the hydropower station are achieved, and an environment-friendly hydropower station in the complete sense is constructed.

Description

technical field [0001] The invention relates to the field of water conservancy and hydroelectric power technology, in particular to a comprehensive energy system of a zero-carbon emission hydropower station. Background technique [0002] Hydropower is a kind of clean electricity, which is basically non-polluting to the environment, but it has not yet achieved zero carbon emissions in the true sense. Within the scope of the hydropower station hub, the main sources of carbon emissions are: [0003] (1) Diesel generators for hydropower stations. The diesel generator is used as the security power supply and the black start power supply of the hydropower station (if there is such an operation mode), which uses the diesel engine to drive the generator to realize electric energy generation. In the case of failure of other power sources in the power station, ensure the safe operation of the hydropower station or start the hydroelectric generator set. During operation, CO will be ...
