摘　　要：在宽频电压测量中,暂态过电压成分严重影响线路电能质量及电力系统安全。传统的测量方法常应用单个微处理器处理数据,较难实现对多路高速数据采集的实时性与同步性,不能实现对于暂态过电压信号的采集,无法满足宽频电压测量要求的问题。本文设计的电压测量系统,利用FPGA运算速度快、内部延时低、硬件并行处理的优势以及ARM通信接口丰富,外设资源多、控制能力强的优点,实现宽频电压信号的高速调理采集、处理与传输。而在数据输入层引入边缘节点,进行数据预筛选,解决数据处理中云端的压力较大,且难以实现实时数据评估的问题,从而提高数据传达的效率。In broadband voltage measurement,transient overvoltage components will seriously affect line power quality and power system security.The traditional measurement method often uses a single microprocessor to process data.It is difficult to realize the real-time and synchronization of multi-channel high-speed data acquisition.It cannot realize the acquisition of transient overvoltage signals and cannot meet the requirements of broadband voltage measurement.The voltage measurement system designed in this paper uses the advantages of fast operation speed,low internal delay,hardware parallel processing of FPGA and rich ARM communication interface,many peripheral resources and strong control ability to realize high-speed conditioning acquisition,processing and transmission of broadband voltage signals.In the data input layer,edge nodes are introduced to perform data pre-screening,which solves the problem that the cloud pressure in data processing is large and it is difficult to achieve real-time data evaluation,thereby improving the efficiency of data transmission.
