| 摘 要： | 结合基于瞬时无功功率理论的ip-iq检测方法和基于传统功率理论的闭环自适应检测方法两者的优点,设计一种新的检测方法,该方法具有较好的鲁棒性和动态响应速度。同时由于逆变器采用三桥臂电容中点式结构,对其直流侧电压的稳定和上下电容的均压控制作了分析,与无功和谐波电流检测结合起来形成了双闭环结构,进一步增强补偿效果,然后对指令电流的合成和其跟踪控制作了简要阐述。最后利用Matlab/Simulink对系统进行了仿真,验证了该方法的正确性和有效性。

| Abstract: | This paper adopts a detection method that combines the advantages of both ip-iq detection method based on instantaneous reactive power theory and closed-loop adaptive detection method.This method is better compared to both in terms of robustness and dynamic response speed.And as the inverter adopts three bridge-arm capacitor mid-point structure,the inverter’s DC voltage stability and upper and lower capacitor’s uniform voltage control are analyzed.And it is with the reactive and harmonic current detection combine to form a double-loop structure to further enhance the compensation effect,then the synthesis of instructions current and tracking control are briefly described.Finally,the system is simulated with Matlab/Simulink,and then the simulation results validate the correctness and validity of the method. |
