| 为了进一步提高功率类数补偿的精确度，该装置采用89C52单片机及6264高速A／D模数转换芯片，实现对电压、电流的交流采样,通过支算获得电压，电流和有功功率，继而获得功率因数并袂现自动补偿。由于采用交流采样技术，实现了信号的实时采集，克服了直流采样误差大和稳定性差的缺点。该装置硬件电路简单，还可实时显示功率因数的大小，并具有过压、欠压监测报警功能。 |

| Abstract: |
| In order to improve the accuracy of power factor compensation,the voltage and current are AC-sampled by the device based on single-chip micro-controller89C52and high speed A/D convertor6264.The values of voltage,current ,active power and power factor are calculated and the automatic compensation is realized.The real-time signal acquisition with AC-sampling technology overcomes the short comings of bad stability and big error in DC-sampling.Its hardware is simple and it can real-time display power factor and support the alarm functions for over-and under-voltages. |
