摘要
针对当前控制方法在对谐振注入式有源滤波器进行控制时,滤波器控制功率与实际需求功率相差较大的问题,提出了基于DSP的谐振注入式有源滤波器数字双环控制方法。采用基波分压或电流旁路方式,连接基波谐振支路,通过逆变器调节实现控制,运用扰动法跟踪谐振注入式有源滤波器最大功率点,根据YI数字编程软件量化、编码离散信号转化为数字信号,基于DSP技术采集和处理数字信号,通过关联谐振滤波器与数字锁相环输出的电网实际角频率,更新控制极点的数值,实现谐振注入式有源滤波器数字双环控制。实验结果表明,该控制方法的滤波器控制功率与实际需求功率相差较小,能够有效降低控制误差。
In order to solve the problem that the control power of the current control method is quite different from the actual demand power,a digital double loop control method based on DSP is proposed.The fundamental resonance branch is connected by the fundamental voltage divider or current bypass mode.The control is realized by inverter regulation.The maximum power point of the resonant injection active power filter is tracked by disturbance method.The discrete signal is quantized and coded according to YI digital programming software.The digital signal is collected and processed based on DSP technology,and output through the associated resonant filter and digital phase locked loop in order to realize the digital double loop control of the resonant injection active power filter,the actual angular frequency of the power grid and the value of the control poles are updated.The experimental results show that the difference between the control power of the filter and the actual demand power is small,and the control error can be effectively reduced.
