Three-phase Reactive Power Measurement Based on DSP and FFT
This paper presents a three-phase reactive power measurement system based on DSP, a cycle of the signal is sampled in equal interval by using software phase-locked, The FFT algorithm is used to calculate power parameters such as reactive power, it provides the basis for real-time reactive power compensation. The hardware circuit design and software design is given in this paper, it has been verified the feasibility and accuracy of the system by actual measurement.
