| Abstract: | A method of the real-time multiple-channel AC data acquisition based 80C196KC microcontroller is introduced. Adopting frequency-tracking method eliminates the effect of frequency change. The data can be restored the real value of voltage and current by Fourier algorithm. The active power, reactive power and power factor can be calculated in 20 ms,and the error of data is limited in 1%. This method has many advantages, such as high speed, high accuracy, and simple structure in hardware. In fact, this method has some practical value. |
