Abstract :
In order to verify the feasibility of OH power supply design, simulation study based on Simulink is carried out. The simulation model includes 300MVA six-phase motor generator, transformers, converters, crowbar, cable and load. The models of transformers, converters and the control system are built in detail. The impedance of AC side includes the one of generator, transformers and cables are estimated. The inductance of interphase reactor is calculated and selected to ensure the current balance in parallel mode and restrain circulating current in circulating current mode. The normal operation and protection strategy of possible faults are discussed. The simulation and analysis results show that the circuit topology is feasible. Output curve is reasonable through optimizing control and circuit parameters.
