本文介绍了一个3.3 kV,1 MVA的三电平PWM转换器的数字控制的设计,作为测试发电机的干扰,在中压电网根据IEC 61000,EN 50160和IEEE 1547等标准。所提出的控制结合了状态反馈与附加的动态输出反馈。它完全在静止参考系中设计,以避免处理到不同旋转参考系的复杂变换。谐振控制器提供零稳态误差高达十次谐波。DSP平台用于实现控制。它取代了商业转换器的控制单元。实验结果的缩小实验板建设验证了控制的功能。
This paper describes the design of a digital control for a 3.3 kV, 1 MVA three-level PWM converter operating as test generator for disturbances in medium-voltage grids according to standards like IEC 61000, EN 50160, and IEEE 1547. The proposed control combines state-feedback with additional dynamic output feedback. It is designed fully in the stationary reference frame to avoid processing of complex transformations into different rotating reference frames. Resonant controllers provide zero steady-state error for up to ten harmonics. A DSP platform is used for implementing the control. It replaces the control unit of a commercial converter. Experimental results of a downscaled breadboard construction verify the functionality of the control.
