摘　　要：文章利用PI调节器融合积分反馈的方法,改善逆变器输出特性的同时,实现逆变器的电容特性;基于容性逆变器在微电网中具有类似无功补偿器的特点,设计逆变器的容性深度为可调,按实际需求调整控制参数进行无功补偿;并对目前逆变器电容特性验证方式的不足,提出一种更加简单、直观、有效的验证方法。通过MATLAB建模,证明了PI调节器融合积分反馈实现的容性逆变器,可改变控制参数补偿无功,同时输出电压波形满足电能质量要求。The method of PI regulator fusion integral feedback is used to not only improve the inverter output characteristics,but also achieve the capacitance characteristics of inverter.Because the capacitive inverter has similar characteristics with reactive power compensator in micro grid,capacitive depth of the inverter is designed to be adjustment,which can adjust the control parameters for reactive power compensation to meet actual requirement.A simpler,more visualized,and more efficient verification method is proposed to improve the current verification method for capacitor property of inverter.On the basis of modeling and simulation using MATLAB,it is demonstrated that PI regulator fusion integral feedback can realize capacitance inverter and change the control parameters of the reactive power compensation,and the output voltage waveform can meet the quality requirements.
