| 摘 要： | 通过实时小波算法在FPGA中的实现来检测暂态电能质量问题。采用高、低通分解滤波器来实现小波变换算法,以DB5小波为基函数,通过对暂态电能质量中五种扰动信号建立分析模型进行仿真并基于FPGA硬件平台进行模拟电能信号测试。对比信号源与测试结果中奇异点起止与持续时间,结果证明了该方法的准确性和可行性。

| Abstract: | This paper proposes a method of realizing wavelet transform algorithm,which is based on FPGA.Using high and low pass decomposition filter to realize wavelet transform algorithm,DB5 is taken as basis function to establish analysis model of five disturbance signal of transient power quality for the simulation and do simulated power signal test based on FPGA hardware platform.Contrasting signal source and test results with the singular point start-stop and duration,the results show that the method is feasibility and accuracy. |
