Design of a Novel Voltage Monitoring Device Based on Consensus Filter

摘要:

在进行深入分析consensus滤波器原理的基础上,提出了一种新的电压监测仪设计方法;首先将数模转换器在各个时刻测量的电压有效值看做一个小世界网络模型G中的一个节点;由于测量的电压信号容易被电网中的随机噪声所污染,通过consensus滤波器算法进行滤波,使得数模转换器测量的信号最终趋近于一个稳定的数值;仿真结果表明,该方法可以有效的还原被噪声污染的电压信号,而且即使在某一个时刻数模转换器出现故障失灵,所测量的数据也不受影响,仿真结果和实践应用表明了文章所提出方法的有效性和可行性。

Abstract:

A novel voltage monitoring device is designed by analyzing the theory of consensus filter. Firstly, a small world networked model is selected as complex network to consensus filter. Then treating the data of AD measured in every cycle time as a node of a small world network and use the consensus filter to filter the measured voltage. The simulation results show the proposed method can give an estimation of the polluted voltage signal and can filter even in some mutation condition.This can illustrate the feasibility and effectiveness of the proposed approach.
