Modeling of MHD (Magnetohydrodynamic Electrical Power Generation) Generators for Transient Stability Analysis

摘要

The objectives of the study were to: (1) model the Magnetohydrodynamic Electrical Power Generation (MHD) channel and power conditioning components in a lumped parameter fashion suitable for transient stability analysis and compatible with channel flow phenomena, particularly shock behavior; and (2) incorporate these models into an appropriate power system to predict the effect of a typical fault on the transmission system connecting the MHD plant to a major network. Modeling work included development of MHD channels in a form suitable for electrical power system analysis and development of time domain models of the inverter and alternator. These models enable shock phenomena to be studied in the MHD channel and diffuser and the effect of system faults on the inverter to be assessed, particularly with regard to its ability to remain in a commutating mode.
