Abstract
THE SUCESSFUL UTILIZATION OF A NEW ELECTRIC GENERATING TECHNOLOGY DEPENDS CRITICALLY ON ITS INTEGRATION WITH EXISTING UTILITY GRIDS FROM THE VIEWPOINTS OF CONTROL, PROTECTION AND STABILITY. THE PROPOSED STUDY DEALS WITH THE INTEGRATION OF ONE NEW SOURCE TECHNOLOGY - MAGNETOHYDRODYNAMIC (MHD) ELECTRICAL POWER GENERATION - THOUGH THE METHODOLOGY WILL BE APPLICABLE TO OTHER NEW SYSTEMS. THE TRANSIENT STABILITY REGIME, THE TIE PERIOD OF 50 MILLISECONDS TO 10 SECONDS AFTER A DISTURBANCE, WILL BE ADDRESSED BECAUSE OF IMPORTANCE RELATIVE TO THE STABILITY OF THE POWER SYSTEM. THE MHD GENERATOR WILL BE MODELED, TAKING INTO ACCOUNT COMPRESSIBILITY EFFECTS SUCH A SHOCK FORMATION. THE MODELING WILL BE IN LUMPED PARAMETER FORM SUITABLE FOR POWER SYSTEM ANALYSIS AND WILL INCLUDE THE POWER CONDITIONING SUB-SYSTEM BY WHICH THE DC OUTPUT OF THE MHD GENERATOR IS CONNECTED TO THE UTILITY GRID. A TYPICAL OPERATIONAL SITUATION WILL BE CONSIDERED AND THE BEHAVIOR OF AN MHD/STEAM COMBINED CYCLE PLANT WILL BE COMPARED WITH ITS CONVENTIONAL COUNTERPART. THE OVERALL MODEL OF THE MHD GENERATOR AND POWER CONDITIONING SYSTEM DEVELOPED IN THE STUDY WILL BE COMBINED WITH EXISTING ALTERNATOR AND INFINITE BUSBAR MODELS TO PREDICT THE EFFECT OF A THREE-PHASE FAULT ON THE TRANSMISSION SYSTEM CONNECTING THE MHD PLANT TO A MAJOR NETWORK.
