摘要
在快周期同步加速器中,为避免无功能量存取对电网的扰动,磁铁电源系统通常采用怀特电路结构。在并联型怀特电路中,降低磁铁电流的高次谐波含量,即电流总谐波畸变率(THD)是保证磁铁电流跟踪精度的关键所在。本文基于一单元并联型怀特电路模型,详细分析了在不同激励源模式下磁铁电流的动态特性,并获得实验验证。结果表明,连续激励模式更有利于改善磁铁电流的THD指标。
In order to avoid drawing a large reactive power from the alternating current line,the White circuit type resonant network is adopted widely as the structure of the magnet power supply system of the rapid-cycling synchrotron.Reducing the total harmonic distortion（THD）of the magnet current in the parallel resonant network is the key technique for the magnet current tracking accuracy.Based on the dynamic response analysis of a single mesh parallel resonant circuit in the paper,it shows that the continuous power excitation is of great benefit to reducing the magnet current harmonics.The paper also gives a description of our experimental studies on the dynamic response with the pulse and continuous power excitation in a parallel resonant network model.
