摘要:

为抑制下垂控制的逆变器并联运行时产生的环流,通过分析传统下垂控制的基本原理及引入虚拟电感下垂控制技术的缺陷,提出在无功功率调整环节加入积分项的控制策略。经仿真验证,所提策略实现了并联逆变器间无功功率的均分,对瞬态和稳态时的环流均有显著的抑制作用。

Abstract:

In order to suppress the circulating current generated during the parallel operation of inverters with droop control.By analyzing the basic principle of traditional droop control and the defects of droop control technology with the introduction of virtual impedance,a control strategy adding an integral term into the reactive power adjustment link is proposed.Simulation results verify that the proposed strategy achieves reactive power the equal sharing among parallel inverters and has an obvious inbitory effect on the circulating currents in both transient and steady-state.

Key words: inverter, droop control, parallel operation, circulating current
