【摘要】 对一种具有谐波补偿功能的微源逆变器进行研究,即在一套逆变装置上同时实现并网和谐波补偿两种功能。首先,将谐波补偿量引入逆变器控制中,实现谐波补偿功能。并且逆变器直流侧的储能装置,可保证对谐波电流进行长时间补偿。其次,依据逆变器容量、发电单元输出及谐波功率,控制逆变器工作在最佳状态。最后,利用Matlab/Simulink验证所设计逆变器的可靠性及控制的有效性。更多还原

【Abstract】 This paper studies the micro-source inverter having a harmonic compensation function, that is, on an inverter device achieve two functions which are connecting to micro-grid and harmonic compensation simultaneously. First, in order to achieve harmonic compensation, harmonic compensation amount added to the control of inverter. And the storage device of the inverter DC side can make sure that harmonic current can be transmitted longer. Second, the inverter is controlled to work in the best condition, according to the capacity of the inverter, the output of power generation units and power of harmonic. Finally, the inverter is proofed to work reliability and to be controlled effectively by Matlab /Simulink.更多还原
