Digital design and implementation of fast power data detector

This paper introduces the digital design and implementation of a fast power data detector operated for the fundamental frequency (50 or 60 Hz). The detector can measure the complete power data, Including rms values of current and voltage, real and imaginary powers, complex power, and power factor simultaneously with quick response time. First, the detection equations are derived. Then, the simulation is made to verify the effectiveness of detection. Finally, the digital implementation is accomplished by using the TMS320C31 floating-point DSP. The experimental results are given for verification.
