摘　　要：在对原有的单台二极管整流系统采用感应滤波方式的新型整流系统改造后,与原有的另外2套6脉波整流系统一并构成了一个包含新型晶闸管整流及常规二极管整流的混合型18脉波工业整流系统。在介绍新型整流系统主电路的基础上,分析了此混合整流系统的数学模型,结合负载实际需求,对混合系统的动态重组及相应的控制模式进行了研究,并通过对比研究确定了各种工况下的最优运行方式。仿真与工程测试研究表明此混合系统具有良好的电能质量及动态稳定特性;同时,基于感应滤波的新型直流供电系统在谐波抑制、功率因数补偿等方面具有优势。Renovating original single diode rectifier system by new type of rectifier system adopting inductive filtering mode and composing the renovated rectifier system with other two original conventional 6-pulse rectifier systems,a hybrid 18-pusle industrial rectifier system containing diode uncontrolled rectifiers and thyristor controlled rectifiers is constituted.Based on the presentation of the main circuit of the hybrid 18-pusle industrial rectifier system,the mathematical model of this hybrid rectifier system is analyzed and combining with actual requirement of the load the dynamic restructure of the hybrid rectifier system and corresponding control modes are researched,and through comparative study the optimal operating modes for different working conditions are determined.Results of simulation and engineering tests show that this 18-pusle industrial rectifier system possesses good dynamic stability,meanwhile due to the superiority of the new type of inductive filtering-based DC supply system in harmonic suppression and power factor compensation the demand on power quality can be satisfied.
