| 摘 要： | 针对有源电力滤波器负载谐波电流的控制,考虑到逆变器开环运行时动态性能差和电流检测所带来的一些误差,可能导致逆变器的输出电流发生过电流而损坏功率器件。在分析注入式混合有源滤波器的基础上,对传统谐波电流单闭环控制增加一个电流负反馈来控制逆变器的输出电流,实现对谐波电流的双闭环控制。保证了逆变器安全可靠运行,提高了整个系统的抗扰性能以及对给定参考谐波电流的跟随性能,仿真结果验证了谐波电流双闭环控制的可行性与优越性。

A Novel Control Strategy of Double Closed Loop for Harmonic Current |
| |
| Abstract: | Aiming at the control of harmonic current of the load,in consideration of the bad dynamic performance of inverter with open-loop operation and some error caused by current detection,may cause the output current of the inverter accessed and then damage power devices.This paper based on the foundation of traditional single closed-loop control increase a current negative feedback to control output current of the inverter,in order to achieve the double-closed loop control of harmonic current.The method ensures the safe and reliable operation of the inverter,improving immunity performance of the entire system as well as the follow performance of a given reference harmonic current.Simulation results show the feasibility and superiority of harmonic current double closed-loop control. |
