船舶中频独立供电系统典型负载模型研究

Research on Shipboard Intermediate Frequency Independent Power Supply System Load Model

船舶中频独立供电系统的应用提高了大容量中频供电系统的运行效率、减小了系统体积。由于负载间的干扰,严重制约了该系统的发展。本文以雷达电源作为典型中频负载,对其供电特性进行了研究。通过对三种电流模型的参数研究,建立了相应的仿真模型,从结果中得出中频供电雷达是整流型非线性负载,而不是脉冲类负载以及不同类型的雷达电源模型可以用不同的整流器来替代的结论,实船中频雷达负载的试验结果验证了相关结论。

The application of shipboard intermediate frequency independent power supply system generates great benefits, such as advanced operation efficiency of high-capacity and small volume; however, it is the load interference which severely restricts its development. In this paper, the radar electricity is chosen as the typical intermediate frequency load, and the power supply feature of the electricity is investigated. Through parameter study of the three current models, the respective simulation models are established, from the computation results, the conclusions, according with the results concluded by real equipment experiment, that the intermediate frequency power supply radar is not a pulse load but a rectifier nonlinear load and different radar electricity models can be substituted by different types of rectifiers are obtained.
