摘　　要：为研究直线式移相变压器整流系统二极管故障时的运行情况,建立了基于有限元场路耦合仿真的直线式移相变压器系统模型,设计了小功率实验样机,分别对直线式移相变压器整流系统中二极管开路故障和短路故障进行仿真与实验。对二极管开路故障时系统输出电压及短路故障时各绕组的相电流进行仿真分析和实验验证,阐明了二极管开路故障和短路故障对系统造成的影响。研究结果可为二极管开路时系统带故障运行的可行性以及二极管短路时系统保护装置的设计提供了理论参考。In order to study the operation of rectilinear phase-shifting transformer rectifier system with diode faults,a rectilinear phase-shifting transformer system model based on finite element field-path coupling simulation is established,and an experimental prototype is built to simulate and experiment the rectilinear phase-shifting transformer rectifier system with diode open circuit faults and short-circuit faults.The output voltage of the system and the phase current of each winding in the case of diode open circuit fault are simulated and verified by experiment.The influence of diode open circuit fault and short circuit fault on the system is illustrated.The results can provide a theoretical reference for the feasibility of the system running with fault when the diode is open and the design of the system protection device when the diode is short.
