| 摘 要： | 变频器等电力电子设备在船舶电网中的使用,将使变频器输入回路产生大量谐波.为减小谐波对电网的污染,对6脉波、12脉波、24脉波整流器的输入侧电流谐波进行了分析,对船舶电力推进系统不同工况下的网侧电流谐波进行了仿真研究.仿真结果表明,多相整流技术是抑制谐波的有效方法,整流相数越多,变频器注入电网的谐波含量越小;24脉波整流应用在船舶推进系统上可大大减小船舶电网的谐波含量,有效地提高电网品质.

| Abstract: | The usage of power electronic devices in ship power grids will produce a large number of harmonics in the input circuit of converters.To reduce the harmonic pollution,the input current harmonics of six-pulse,twelve-pulse and twenty-four-pulse rectifiers were analyzed.The net side current harmonics were separately simulated when ship electric propulsion system in different operating modes.The results verify that multi-phase rectifier technology is an effective way to suppress harmonics.The phases of rectifier are more,the harmonic content of inverter into the grids is smaller.Using twenty-four-pulse rectifier in ship electric propulsion system can greatly reduce the harmonic content,and improve the quality of grids effectively. |
