| 摘 要： | 提出了一种逆变器无互连线并联系统的基准信号同步和均流控制解耦的控制思想，研究了基于电力线通信(PLC)的基准同步先行的并联控制方法以及基于数字信号处理器(DSP)的实现。研究了基于PLC的各模块基准信号相位判断方法和同步调节算法，实现了各基准信号始终保持同频同相。在基准同步先行的基础上，提出了基于PLC的均流控制策略，经PLC通信得到无功功率差信息，采用累加算法实现了无功功率的均分。在逆变器双机并联系统中进行实验，证实了控制策略的有效性和可行性。

| Abstract: | A novel voltage reference synchronization and output current distribution decoupling control for wireless parallel inverters is proposed. Based on power line communication (PLC) and digital signal processor (DSP), the pre- synchronized voltage reference signal is generated beyond the current distribution control in each module. The reference phase differentiation and synchronization regulation algorithm are researched. The current distribution control based on PLC is proposed, and the reactive power distribution is realized by implementing the accumulative power regulating algorithm. Experimental results are obtained in the dual-module parallel system to verify the validity and feasibility of the proposed control. |
