摘要
提出了一种采用现场可编程门阵列(简称FPGA)实现交流系统功率测量的方法.FP GA中采用离散数学的方法实现DSP算法用于交流系统的功率测量,由于FPGA具有较高的分辨率和较好的性能,使功率测量精度不再受传统处理机的分辨率所限,测量的精度得到提高.文中采用硬件高精度的方法实现数字积分功能,克服了由于电压电流的波形偏离正弦波所带来的测量误差,为交流系统功率测量提供了一个高精度、快速的测量方案.
This paper proposed a fast and high precision measuring method to measure the power of AC system. In Field Programmable Gate Arrays (FPGA) to implement digital signal processing algorithms, the performance levels achieved are orders of magnitude greater than those obtained with traditional digital signal processors. Because of the use of circuit to implement the digital integrators, the measuring error from wave distortion of voltage and current can be reduced.
