New Power Consolidation-Inversion-Control System for Faraday MHD Generator.

The authors propose a new power consolidation-inversion-control system for the Faraday MHD generator using the voltage source PWM inverters. The dc output power for each electrodes pair of the MHD generator is at first inverted into three-phase ac power by a voltage source PWM inverter, and then the ac powers are consolidated by transformers. The proposed system does not need such expensive equipment as an ac filter or phase modifier and can independently and simultaneously control the active and reactive powers provided to the electric power system. Numerical simulations of the whole system, including the Faraday MHD generator, the proposed system can stably and steadily transit and control the electric power from the MHD generator to the electric power system. It is also confirmed that the proposed system can be independently and simultaneously control the active and reactive powers and can be used as a fast power controller. [ABSTRACT FROM AUTHOR]
