The invention provides a hydropower station security power supply based on a hydrogen energy fuel cell. The hydrogen source is transported to a hydrogen storage device through a pipeline for storage.Hydrogen in the hydrogen storage device is transported to a hydrogen fuel cell through the pipeline as a raw material. The output end of the hydrogen fuel cell is electrically connected with the inputend of an inverter device. The output end of the inverter device is electrically connected with the AC voltage bus of a hydropower station power system. The AC voltage bus of the hydropower station power system is electrically connected with the input end of a security load. The direct current outputted by the hydrogen fuel cell is converted into alternating current by the inverter device and then outputted to the AC voltage of the hydropower station power system to supply power to the security load. A hydrogen transmission control unit is arranged on the pipeline between the hydrogen storagedevice and the hydrogen fuel cell. The hydropower station security power supply also comprises a hydrogen-electricity combined control device which is electrically connected with the hydrogen transmission control unit, the hydrogen fuel cell, the inverter device and the AC voltage bus. The new security power supply mode for the hydropower station has completely zero emission and is clean and environment-friendly.
Description
technical field [0001] The invention relates to the technical field of water conservancy and hydroelectric power, in particular to a safety power supply for a hydropower station based on a hydrogen energy fuel cell. Background technique [0002] In order to obtain the water energy drop, medium and large-scale hydropower stations generally have water storage and flood control facilities such as dams. The normal opening and closing of gates of these facilities is directly related to the safety of the entire power station. Therefore, the hydropower station sets up security power sources for these important electricity loads to ensure the normal operation of these facilities. In addition, fire-fighting equipment, leakage and drainage equipment, elevators, etc. in the hydropower station are also security loads. At present, the security power supply of the hydropower station adopts the cold standby mode of diesel generators. [0003] The security power supply of diesel generator...
