摘要/Abstract

摘要：

多逆变器并联运行时,由于各逆变器的设计参数、连线阻抗等都存在差异,各逆变器模块的等效线路阻抗也各不相同,往往会产生系统环流,导致系统不稳定。本文将对逆变器并联运行系统进行分析,并且提出一种基于虚拟阻抗的逆变器并联运行环流抑制方法。

关键词: 并联逆变器, 环流分析, 主从控制, 虚拟阻抗

Abstract:

When multiple inverters are operated in parallel, because the design parameters and connection impedance of each inverter are different, the equivalent line impedance of each inverter module is also different. Therefore, system circulation will often occur, and it will lead to system instability. In this paper, the inverter parallel operation system is analyzed and a method based on the virtual impedance parallel operation of the inverter is proposed to suppress the circulation.

Key words: Parallel inverter, circulation analysis, master-slave control strategy, virtual impedance
