Abstract: A method for preparing iron alloy and a cement material, in the field of solid waste recycling, provides an efficient, synergistic effect between main components of carbon, calcium and heavy metal in municipal solid waste incineration (MSWI) fly ash and main components of iron, aluminum and silicon in red mud, so that the iron alloy and cement material can be readily obtained. By using waste to treat waste and using the complementarity of the components of two waste streams, carbon in the MSWI fly ash may provide a reductant to accelerate an iron mineral in the red mud to reduce into metal iron. With the formation of the metal iron, a siderophile heavy metal element in the MSWI fly ash is also accelerated to enter an iron phase. Meanwhile, the cement material is formed by Al2O3 and SiO2 in the red mud and CaO in the MSWI fly ash.

Abstract: The present invention discloses a voltage reference reconfiguration fault-tolerant control method for a cascaded multi-level inverter. The fault-tolerant method for the inverter automatically reconfigures the three-phase voltage amplitudes and phases of the three-phase total voltage in accordance with the fault diagnosis, thus realizing three-phase voltage balance. On the basis of the reconfiguration of the total voltage signal, re-reconfiguration of reference voltage inputted into the various H-bridges is conducted in accordance with the fault signal vectors, thereby realizing removal of the fault bridges and fault-tolerance of the normal bridges, while guaranteeing the integral sinusoidal characteristics of the actual reference voltage. The inverter realized maximum three-phase balanced line voltage in a fault occurrence, has the advantages of requiring no redundant modules and algorithms and the advantages of ease of removing fault bridges, and is applicable for reduced load operable electrical equipment.
