摘要
传统方法实现的逆变器并联系统功率分配比例系数都是固定不变的,并不能很好地实现逆变器并联系统的智能化。因此从逆变器并联系统功率灵活分配的性能要求出发,将多智能体技术引入到三相逆变器并联系统中。首先,基于dq0坐标系下三相逆变器输出阻抗的分析,对系统功率加权平均的控制技术进行了研究;接着,根据多智能体系统的主要特征,分析将多智能体技术应用于分布式三相逆变器并联系统的原因和优势。然后,对基于多智能体技术的三相逆变器并联系统功率灵活分配工作原理进行了详细的分析;实验表明多智能体技术能够很好地实现三相逆变器并联系统功率分配的灵活性和自主性。
The power distribution coefficients of parallel inverters system are unchangeabletraditionally,which limits the realization of intelligent parallel inverters system.In this paper,in orderto achieve flexible power distribution,three-phase parallel inverters system is combined withmulti-agent technology.Firstly,the power weighting distribution control technique is investigatedbased on the analysis of three-phase inverter output impedance in dq0coordinate.Secondly,accordingto the primary characteristics of multi-agent system,the reasons and advantages of multi-agents appliedto distributed three-phase parallel inverters system are discussed in detail.Then,the flexible powerdistribution of three-phase parallel inverters system based on multi-agent technology is illustrated.Finally,the experimental results demonstrate that the flexibility and autonomy of power distribution forthree-phase parallel inverters system can be realized well by multi-agent technology.
