BEHAVIOR OF He-Cs CLOSED-CYCLE DISK MHD GENERATOR CONNECTED TO ELECTRIC POWER SYSTEM THROUGH LINE-COMMUTATED INVERTER

摘要

The basic characteristics of He-Cs closed-cycle disk MHD generator connected to an electric power system through a line-commutated inverter are investigated in detail by carrying out time-dependent numerical simulations for the whole interconnecting system. The simulation model is assumed to consist of the closed-cycle disk MHD generator with 100 MW thermal input and 40 MW electrical output, the double-bridge line-commutated inverter, the a.c. filter, the phase modifier, the double-circuit transmission line and the infinite bus. It is made clear that the generator is stable, and its performance is excellent at the nominal operating condition.
