基于FPGA的交流电测量仪的设计

AC sampling measurement unit design based on FPGA

根据交流采样的原理,设计出基于FPGA开方算法,解决了实时计算电压有效值和频率的问题。充分发挥FPGA硬件并行计算的特性,实现高速运算和可靠性的结合,能够较好地解决精度与速度的问题。为稳定控制装置快速判断元件故障提供了充足时间,满足电力系统实时性、可靠性的要求。

The design of square root based on AC analog sampling theory in the FPGA is important to solve the question which is about virtual value and frequency of voltage. We accomplish precision and high speed successfully with parallel computation, and offer enough time to judge trouble. It can meet the needs of real time control and stabilization for electric power system.
