So it is very valuable to design a three-phase power supply quality monitoring system include measure, display, communication and high efficient, low cost, high reliability which is used in power distribution room as monitoring device. 所以设计一个集测量、显示和通信一体的高效率、低成本、高可靠性的三相供电质量的监测系统,用于配电室中作为监控装置是很有价值的。
Hardware design is based on DSP chip and microcontroller. Power date is calculated by DSP so that can achieve power quality monitor and other related functions. The microcontroller is responsible for control, display, communication and other functions. 硬件设计以DSP芯片和单片机为核心,通过DSP完成数据计算,实现电能计量以及电能质量监测等相关功能,而单片机负责控制、显示、通信等功能。
Computer power quality standards based on analysis of the signal, power supply bus through the man-machine interface display, equipment, transformers and power quality parameters important for the more limited the alarm signal on the line reactive power compensation needed to provide raw data. 计算机根据电能质量标准对信号进行分析,通过人机界面显示供电母线、变压器和重要设备的电能质量参数,对越限的信号进行报警,对需要无功补偿的线路提供原始数据。
