摘要:
 中压传动三电平变流器广泛应用于工业传动领域,在某些超大功率场合,需要多重化应用,而网侧谐波指标一直是网侧变流器重点优化的目标。文章分析了一次侧串联绕组变压器的谐波最优实现原理,提出了一种基于单电流闭环的两重化网侧变流器谐波优化控制策略及变压器直流偏磁综合补偿方法,最终在两重化中点箝位型三电平IGCT 变流器机组上进行了对比试验验证。试验结果表明,采用该控制方式显著降低了网侧电流谐波含量和幅值。
Abstract:
 High-power three-level voltage source converters are widely used in high performance AC drive systems. In some superpower occasions, it is very important to reduce the harmonics at grid side by using multiple rectifying applications. In this paper, the
principle of harmonic optimal realization of a series winding transformer on the primary side is analyzed, and a harmonic optimal control strategy based on single current closed-loop and a comprehensive compensation method for DC bias of transformer is proposed. The experimental results show that the proposed control strategy can reduce the converter input current harmonics significantly.
