逆变器能耗与其功率分配之间存在直接联系,当功率分配不合理时,逆变器的能耗较高.为了降低逆变器能耗,提升负荷波动环境下逆变器能量转换的可靠性,提出面向功率灵活分配的逆变器能耗控制方法,分析逆变器运行特性,在此基础上构建两个逆变器并联的等效电路,根据下垂控制方程设计用于能耗控制的逆变器下垂控制器,采用控制器对逆变器运行过程中的有功、无功功率展开灵活分配,以此控制逆变器的运行能耗.实验结果表明,所提方法的功率分配效果好、在负载波动环境下控制适应性和可靠性强、能耗较低.
Research on Energy Consumption Control of Inverters for Flexible Power Allocation
There is a direct connection between the energy consumption of the inverter and its power distribution.When the power distribution is unreasonable,the energy consumption of the inverter is higher.In order to reduce inverter energy consumption and improve the reliability of inverter energy conversion in load fluctuation environments,a flexible power allocation oriented inverter energy consumption control method is proposed,and an inverter operation model is established.Based on this,an equivalent circuit model of two inverters in parallel is constructed.According to the droop control equation,an inverter droop controller is designed for energy consumption control.The controller is used to control the active power Flexible allocation of reactive power to control the operational energy consumption of the inverter.The experimental results show that the proposed method has good power allocation performance,strong control adaptability in load fluctuation environments,and low energy consumption.
