摘要
为了解决传统弱电网逆变器谐波控制方法控制效果差的问题,引进现场可编程逻辑门列阵(Field Programmable Gate Array,FPGA),设计了一种全新的逆变器谐波控制方法。建立逆变器等效控制模型,提取弱电网逆变器谐波峰值,对逆变器的开环与闭环调节,对谐振频率偏移进行补偿,实现弱电网逆变器谐波的精准控制。实验结果表明,所设计的控制方法在实际应用中的效果较好,可以实现对谐波的有效控制。
In order to solve the problem of poor control effect of traditional inverter harmonic control method in weak current network,Field Programmable Gate Array(FPGA)is introduced to design a new inverter harmonic control method.The equivalent control model of the inverter is established,the harmonic peak value of the weak grid inverter is extracted,the open-loop and closed-loop adjustments of the inverter are made,and the resonance frequency offset is compensated,so that the harmonic of the weak grid inverter can be accurately controlled.The experimental results show that the control method designed in this paper has a good effect in practical application,and can achieve effective control of harmonics.
