Conference center standby power system and power supply control method

Abstract

The invention discloses a conference center standby power system and a power supply control method. The invention belongs to the technical field of new energy power storage and supply. The system comprises a plurality of methanol-water reforming hydrogen fuel cell generators which are connected in parallel and a power distribution cabinet; a lithium iron phosphate battery pack, a busbar and a grid-connected inverter are arranged in the power distribution cabinet; the anode and the cathode of each methanol-water reforming hydrogen fuel cell generator are respectively connected with the anode and the cathode of the busbar through cables; the anode and the cathode of the lithium iron phosphate battery pack are respectively connected with the anode and the cathode of the busbar through cables;the anode and the cathode of the busbar are respectively connected with the anode and the cathode of the grid-connected inverter; the output of the grid-connected inverter is connected with a mains supply transmission line to supply power, and the frequency and the phase of alternating current output by the grid-connected inverter are synchronous with those of mains supply respectively. When themains supply is powered off, the lithium iron phosphate battery pack provides electric energy for a short time, the generators provide long-time power supply, the whole system is relatively independent and easy to assemble and move, and compared with the prior art, the system has the advantages of safety, reliability, energy conservation, environmental protection and quick response.

Description

technical field [0001] The invention relates to the technical field of new energy storage and power supply, in particular to a conference center power backup system and a power supply control method. Background technique [0002] With the development of society and the increasing frequency of international exchanges and cooperation, various conferences, technical exchange meetings, and press conferences are increasing; for some high-level, important, or influential conferences, the organizers will definitely prepare for them system. If the mains power fails, the backup power system will start immediately to provide uninterrupted power supply for the hardware facilities necessary for the meeting (such as: air conditioning, video system, communication system, audio system, lighting system, etc.). Make sure the meeting runs smoothly. [0003] In the prior art, people first consider the use of diesel generator sets. However, diesel generators have many obvious disadvantages: 1...

Problems solved by technology

[0003] In the prior art, people first consider the use of diesel generator sets. However, diesel generators have many obvious disadvantages: 1. The smoke generated by generator fuel seriously pollutes the air; 2. Noise and vibration pollution generated during generator operation environment; 3. The generator set takes a long time to start; the above reasons determine that diesel generator sets are not suitable for use under many conditions

The world's problem with hydrogen application today is storage
