能量回馈型四象限电力电子负载在船舶电力系统动模试验中的应用

目前，随着船舶综合电力系统的发展，船用负载设备类型的增多导致目前交直流动模试验室无法真实模拟系统动态特性。为研究和分析能量回馈型四象限电力电子负载船舶电力系统动模试验的应用，本文通过分析四象限电力电子负载的拓扑结构和控制方式，在Matlab/Simulink仿真平台和动模试验室中分别进行了能量回馈型四象限电力电子负载相关功能试验。仿真和试验结果表明，能量回馈型四象限电力电子负载能够模拟不同类型的负载以及不同电压、功率等级的电源，并且在模拟负载时，能够将吸收的电能高效地反馈回电网，不仅可以提高工作效率，还能够起到节约电能的目的。

Application of Energy Feedback Power Electronic Load Based on the Four-quadrant in Ship Power System Dynamic Physical Simulation

With the development of the ship integrated power system, the increase in the type of marine load equipment has led that the AC/DC laboratory cannot realistically simulate the dynamic characteristics of the system. In order to research and analysis application of energy feedback power electronic load based on the four-quadrant in ship power system dynamic, by analyzing the topology and control mode in this paper, functional experiment of the energy feedback power electronic load is carried out in Matlab/Simulink simulation platform and dynamic model laboratory. The simulation and experimental results different types of loads and power source of different voltages and power levels can be simulated in energy feedback power electronic load. In addition, when in the load mode, the absorbed energy can be efficiently fed back to the grid, which not only improves work efficiency, but also saves energy.
