摘　　要：对基于Fryze功率理论的FBD谐波电流检测算法进行了分析,论证了FBD法与ip-iq法的一致性。与ip-iq法相比,FBD法没有复杂的Park变换及其反变换,可更快速地用于单相、三相三线制、三相四线制的谐波和无功电流实时检测。设计了基于DSP-FPGA的全数字控制系统,综合DSP强大的数据处理能力和FPGA的逻辑控制方法,能大大提高整个系统的稳定性。仿真和试验结果表明,基于FBD法的谐波检测方法检测实时性好,精度高,易实现,具有实用价值。Analysis was made on the FBD algorithm based on Fryze＇s power theory for the harmonic currents detection and the consistency of the FBD and i p-i q was demonstrated.Compared with i p-i q method,FBD algorithm has no complicated Park transformation and the corresponding inverse transformation,so it can be applied to single-phase systems,three-phase three-wire systems and three-phase four-wire systems for the real-time detection of the harmonic and reactive currents.A fully digital control system based on DSP-FPGA was designed.The powerful data processing ability of DSP was integrated with the logical control of FPGA,which improved the stability of the whole system greatly.Simulation and experiment results show that the proposed detection method based on FBD is with real time,high precision and easy implementation as well as practical use.
