Abstract

The invention provides a hydropower station hydrogen energy uninterrupted alternating current power supply system, which comprises a hydropower station hydrogen production system, a hydropower stationhydrogen storage system, a hydrogen conveying pipeline, a hydrogen fuel cell stack, a UPS main cabinet, a UPS power distribution cabinet and a power station service alternating current, wherein the output end of the power station service alternating current is electrically connected with the input end of a rectification module and the input end of the UPS main cabinet; the output end of the rectification module is electrically connected with the input end of the hydropower station hydrogen production system; the output end of the hydropower station hydrogen production system is communicated with the input end of the hydropower station hydrogen storage system through the hydrogen conveying pipeline; the output end of the hydropower station hydrogen storage system is communicated with the input end of the hydrogen fuel cell stack through the hydrogen conveying pipeline; the output end of the hydrogen fuel cell stack is electrically connected with the input end of the UPS main cabinet; the output end of the UPS main cabinet is electrically connected with the input end of the UPS power distribution cabinet; the output end of the UPS power distribution cabinet is electrically connectedwith the input end of the rectification module. According to the invention, the requirements of zero emission and zero pollution can be realized in the long-term operation and maintenance process.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydroelectric machines, in particular to a hydrogen energy uninterrupted AC power supply system of a hydropower station. Background technique [0002] Important equipment such as computer monitoring hosts, servers, communication equipment, and fire alarms in hydropower stations need to provide reliable uninterruptible power supplies (hereinafter referred to as UPS). Under normal operating conditions, the UPS rectifies the AC power into DC power, and then inverts the DC power into a stable and impurity-free AC power; when the AC power is interrupted (accidental power outage), the UPS immediately converts the DC power of the battery through the inverter switching method Continue to supply 220V AC to the load to keep the load working normally. At present, UPS batteries generally use lead-acid or nickel-cadmium batteries. Lead-acid and cadmium-nickel are corrosive and toxic to a certai...
