摘要
分析电源的5个指标(电压偏差、频率偏差、谐波、电压波动和闪变、三相不平衡度),提出一种基于LABVIEW的电源监测系统。从电压互感器和电流互感器的次级引入输入信号,形成适宜于模数转换器处理的电压信号,经过抗混叠滤波器,滤去高频的干扰噪声,在经过采样保持,A/D转换,将采集数据送PC处理,最终完成计算分析、显示、存储及打印等功能。
Analyze 5 index marks of power unit （voltage deviation, frequency deviation, harmonic wave, voltage fluctuation and flicker, tri-phase degree of unbalance degree）, and design a power monitoring system based on LABVIEW. Lead in input signal from voltage and current mutual-inductor, transform it into voltage signal suitable for analog-to-digital converter, process it with anti-intermixing-stacking filter and get ride of its noise, then sample, maintain, A/D convert and send it to PC for further process. At last realize functions like computation and analysis, display, store and print.
