摘要:
强磁场科学中心外超导磁体电源为大电感负载的相控整流电源,其电网侧会产生大量的无功与谐波,不仅影响电网质量还可能影响外超导电源本身的控制。针对外超导电源的特性,对各种无功补偿方案进行了分析比较,阐述了选用SVG作补偿装置的原因。搭建了三相三电平的SVG仿真控制模型和30 kvar的样机实验平台,实验表明了该方案的可行性。

Abstract:
The external superconducting magnet power supply of the High Magnetic Field Laboratory is a phase-controlled rectified power supply with large inductive load,resulting in a large amount of reactive power and harmonics on the grid side, which not only affects the quality of the power grid but also affects the control of the external superconducting power supply itself. Aiming at the characteristics of external superconducting power supply, the various reactive power compensation schemes are analyzed and compared, expounded the reason why used SVG compensation device. Built.a three-phase three-level SVG simulation control model and a 30 kvar prototype experimental platform .The experiment shows the feasibility of the scheme.
Key words:  RectifierCircuit  SVG  Static vargenerator  Matlab
