电能质量监测系统设计

Design of monitoring system of power quality

针对电能质量受到短路、断路、漏电、谐波等因素影响的问题,设计了一种基于DSP的多功能电能质量监测系统,详细介绍了该系统3个组成部分即前端信号采集电路、下位机、上位机分析软件的设计。实验结果表明,该系统可实时检测及计算电压、电流、功率、功率因数、频率、谐波等电力参数,具有较好的监测效果。

In view of problem that power quality is influenced by factors of short circuit,open circuit,leakage and harmonics,a monitoring system of power quality with multifunction based on DSP was designed.Design of three parts of the system namely front signal collection circuit,lower computer and analyzing software of upper computer were introduced in details.The experiment result showed that the system can real-timely detect and calculate power parameters of voltage,current,power,power factor,frequency and harmonics and it has better monitoring effect.
