摘　　要：利用Multisim仿真软件对船舶同步发电机并联的实际运行进行仿真;利用向量图分析待并发电机和运行发电机在电压不相等、初相位不相等和频率不相等三种不同条件下的并联运行,实验在条件偏差不大的情况下,可以使待并发电机牵入同步,而不会使线路和发电机有较大损坏。同时仿真显示了发电机和汇流排输出的电压、电流波形,验证了两台发电机之间冲击电流的存在和影响。使用Multisim仿真软件使电路中各种电压波形和冲击电流的大小显示变得更加直观、具体、生动。Multisim simulation software is used to simulate the actual operation of ship synchronous generator in parallel.The parallel operation of the stand-by generator and the running generator is analyzed by using the vector diagram under three different conditions,that is,the voltage is not equal,the initial phase is not equal and the frequency is not equal.Under the condition of little deviation,the experiment can make the stand-by generator pull into synchronization,without causing great damage to the line and generator.At the same time,the voltage and current waveforms output by the generator and bus bar are simulated to verify the existence and influence of the inrush current between the two generators.The use of Multisim simulation software makes the display of various voltage waveforms and inrush currents in the circuit more intuitive,specific and vivid.
