Abstract

FFT is a kind of algorithms of reactive power measurement. It has high measurement precision and can be easily implemented on hardware. Now it is widely used in reactive power measurement. FPGA model of reactive power measurement based on FFT is put forward in this paper. Two ways to achieve FFT results are designed in this paper. One way is to use FFT IP core provided by Altera Company, and the other way is to design FFT by ourselves with programs. The system is implemented on EP2C50 series FPGA chips of Altera Company. Some characteristics of the system such as precision, speed and resource consumption are analyzed in details.
基于FFT的无功功率测量系统的FPGA实现
FFT是一种无功功率测量算法。测量精度高,易于硬件实现。目前已广泛应用于无功功率的测量中。提出了基于FFT的无功功率测量FPGA模型。本文设计了两种实现FFT效果的方法。一种方法是使用Altera公司提供的FFT IP核,另一种方法是自己用程序设计FFT。系统是在Altera公司的EP2C50系列FPGA芯片上实现的。详细分析了系统的精度、速度和资源消耗等特点。
