| 中文摘要 | LCL作为三相电压型有源整流器的输入滤波器存在稳定性问题,通常安置阻尼电阻以避免系统发生谐振。为使LCL滤波的有源整流器在无阻尼电阻的情况下稳定运行,以电压空间矢量控制为平台,提出引入交流滤波电容电流环的主动阻尼控制策略,改变了系统原本不稳定的极点。考虑采样保持、运算及PWM更新引入的延时,建立了包括电流控制环和LCL滤波器在内的存在一个采样周期延时的简化离散模型,并在z平面分析系统的稳定性,优化滤波电容电流环的放大系数。LCL滤波的电压型有源整流装置实验结果表明,整流器未发生电流谐振现象,证明了所提出的主动阻尼控制策略及稳定性分析方法的正确性。; Three-phase VSR(Voltage Source active Rectifiers)with LCL-filter as its input filter usually has stability problems,for which the damping resistors are used to avoid resonance.In order to stabilize the ope- ration of VSR without damping resistors,the active damping control strategy is proposed for AC capacitor current loop of voltage oriented control,which changes the unstable poles of LCL-filter.A simplified dis- crete model including the current control loop and LCL-filter is established with the time delay of one sam- pling period,induced by S/H(Sampling and Holding),processing and modulation.Its system stability is analyzed in z-plane and the amplification coefficient of AC capacitor current loop is optimized.The experi- mental results of a three-phase VSR with LCL-filter demonstrate no resonance occurs in rectifier,which validates the correctness of proposed control strategy and stability analysis. |
