摘要/Abstract

摘要： 本文使用新型中点箝位型（NPC）三电平储能变流器作为研究对象,结合矢量控制原理,在abc自然坐标系下提出一种用于三电平储能变流器的新型矢量控制方法。首先建立了储能变流器的数学模型,结合对矢量控制的原理分析,提出一种abc自然坐标系的新型矢量控制方法。然后在MATLAB /Simulink仿真软件中搭建了仿真实验平台。实验结果表明本文方法可以在无坐标变换和锁相环的情况下,实现有功、无功电流的独立控制,系统运行稳定良好。

关键词: 三电平储能变流器, abc自然坐标系, 矢量控制, 锁相环

Abstract: A new type of neutral point clamped (NPC) three-level energy storage converter is studied in this paper. Combined with the vector control principle, a new vector control method for the three-level energy storage converter is proposed in abc natural coordinate system. A mathematical model of energy storage converter is established, and a new vector control method of abc natural coordinate system is proposed with the aid of principle analysis of vector control. Then a simulation experimental platform is built in MATLAB/Simulink simulation software. The experimental results show that the method proposed in this paper can achieve independent control of active and reactive current without coordinate transformation and phase-locked loop, and can ensure stable operation of the system.

Key words: three-level energy storage converter, abc natural coordinate system, vector control, phase-locked loop
