基于DSP的电能质量监测装置的设计与实现

Design and Implementation of Equipment for Power Quality Monitoring Based on DSP

针对传统电能质量监测系统的不足,提出了一种基于TMS320F2812的监测电能质量新方法。本系统主要利用DSP芯片强大的数据处理能力和丰富的系统资源,对同步采样来的信号进行处理,从而对电能质量的五项指标进行分析、存储。实验结果表明,TMS320F2812对数据的处理速度满足实时性要求,本系统能够快速、准确地反映出电力系统中电能质量各项指标的变化情况,很好地适应了电力系统对电能质量监测的要求。

Focused on the shortcoming of traditional monitoring systems of power quality, this proposed a new monitoring method of power quality, which is based on TMS320F2812. The system processes the synchromous sampled signals with its powerful data-processing capability and a wealth of system resources of DSP, thus being able to analyse and display the five targets of the power quality. The results show that the speed of TMS320F2812 processing data can satisfy the requirement of online monitoring. The system can reflect the changes of each power quality target quikely and accurately. Therefore,the system can be well adapted to the power quality monitoring requirements.
