摘　　要：介绍了基于高性能DSP芯片ADSP21161和S3C2410 ARM芯片实现的电能质量分析仪的设计方法。以DSP芯片为核心实现数据采集及处理,以S3C2410芯片为核心实现数据管理、人机界面及系统控制,同时采用WinCE嵌入式操作系统作为系统软件平台。该方案提高了系统的智能化及可靠性,降低了系统功耗并有利于系统扩展。测试结果表明该分析仪的各项指标均满足IEC电能质量测试标准。The design of power quality analyzer based on a high performance DSP of ADSP21161 and an ARM chip of S3C2410 are introduced,DSP is used as the core of data acquisition and processing,accompanied with S3C2410 chip as the core of data display and system control,and embedded operation system WinCE is adopted as software of system. The scheme ad- vances the intelligence and reliability of system,reduces the system power consumption and it is good for function expanding. The test results show that the analyzer meet the IEC standards for power quality.
