摘　　要：介绍了一台自主研发的多路动态谐波检测装置,该装置的主要特点是采用了分布式的系统构建方案,采用DSP嵌入式系统模块作为各路动态谐波的检测终端。根据改进的广义d_k -q_k旋转坐标变换检测法,该装置能够适用于三相三线制和三相四线制系统中电压/电流畸变且不对称的场合。各检测终端将处理后的采样数据用UDP协议传送给上层应用软件,从而实现多路动态谐波的实时检测和记录。A multi-channel device for dynamic harmonics detection is introduced. The main feature of this device is that it adopts distributed system scheme and uses the DSP embedded system module as the dynamic harmonics detection terminal. Based on the generalized dk-qk coordinate transform, this device can detect distorted and unbalanced voltages/currents of three-phase three-wire or four-wire system. The sampling data are processed in the detection terminal and transferred to the upper layer application software by UDP protocol, then multi-channel dynamic harmonics real-time detection and record can be realized.
