摘　　要：传统12脉波工业整流系统仍会产生大量谐波和无功,研究了一种基于感应滤波技术的新型12脉波工业整流系统,通过仿真分析研究其在谐波抑制方面的优越性。在阐述了感应滤波技术滤波机理的基础上,利用MATLAB/Simulink中电力系统仿真模块(PSB)工具,建立感应型换流变压器及其滤波单元构建的新型12脉波工业整流系统仿真模型,通过与传统12脉波整流系统对比仿真研究,使用感应滤波时仿真结果网侧谐波THD仅为0.73%,表明了感应滤波技术能将谐波抑制于阀侧,避免其经过变压器流入电网并能减少对设备的损耗及谐波对电网的影响。A new type of 12-pulse industrial rectification system based on induction filter technology is studied, and its advantages in harmonic suppression are analyzed by simulation. On the basis of expounding the filtering mechanism of induction filter technology, a new 12-pulse industrial rectification system simulation model of induction converter transformer and its filter unit is established by using the power system simulation module(PSB) in MATLAB/Simulink. Compared with the traditional 12-pulse rectifier system, the simulation results show that the THD of the network side is only 0.73% when the induction filter is used, the utility model can avoid the harmonic wave flowing into power network through transformer and reduce the loss of equipment and the influence of the harmonic wave on the power network.
