Water electrolytic hydrogen production and minitype gas turbine-switch reluctance motor united generating set

Abstract

The invention pertains to the field of water-electrolytic hydrogen making and power generation by a micro turbine and relates to a combined water-electrolytic hydrogen making and power generating machine made up of a micro turbine and a switched reluctance motor, including the micro turbine, a high-speed switched reluctance motor and water-electrolytic hydrogen making equipment; wherein the micro turbine is directly connected with the high-speed switched reluctance motor by a shaft and the current of the switched reluctance motor is connected with the grid through an inverter. The input end of the inverter is also connected with a DC-DC converter, which provides electric energy for the water-electrolytic hydrogen making equipment. The hydrogen produced by the water-electrolytic hydrogen making equipment serves as the fuel of the micro turbine. The combined power generator makes use of the direct connection between the micro turbine and the high-speed switched reluctance motor and simultaneously adopts the power generating method by which the water-electrolytic hydrogen making equipment is adopted to improve the efficiency of the micro turbine system so as to realize more proper recycling use of the energy.

Problems solved by technology

However, the existing micro gas turbines generally adopt the direct coupling or indirect coupling with the permanent magnet synchronous motor for power generation. The permanent magnet synchronous motor is prone to loss of magnetism at high speed, the reduction gearbox is expensive, and the mechanical characteristics of the rotor are poor, and the permanent magnet synchronous motor is used. AC-DC-AC or AC-AC power converters are generally required for electric motors to generate electricity

At the same time, the storage and transportation of fuel for power generation by micro gas turbines also limits its application in more occasions
