A digital measuring method for power system harmonic impedances is presented.Based on the idea of injecting current to the power system and measuring harmonic impedances directly,a digital receiving set is designed to receive harmonic signals from the power system.To obtain the harmonic impedances,the signals are handled by digital filters.Simulation results show that this measuring set fits the requirement of industrial measurement.

The great gap between the high-speed data flow from A/D converter and low-speed of DSP is a bottleneck limiting the study of radar digital receiving system. The polyphase filter structure of the wideband digital down conversion (DDC) is deduced from the structure of the conventional digital downconverter. Its channels are 50% overlapped. It can realize the high speed and efficient filtering by using the parallel structure and only calculate the decimated data,thus improving the operational efficiency and realizability. The correctness and the validity are proved by the computer simulations and the field programming gate array (FPGA) implementation.
