摘要:
传统电力参数测量基于单片机、采样／保持器和通用A／D变换器，精度和实时性均较差，难以满足高精度实时测控系统要求。文中分析了三相电参数测量的特点，介绍了一种32位ARM7TDMI嵌入式微处理器S3C4480X和ADS7864电力专用A／D芯片的接口方法。这种结构可以简化硬件电路，缓解数据采集的实时性和精度之间的矛盾，在实时多任务操作系统的管理下，可方便地实现电力参数采集、软件数字滤波、谐波分析等功能．已应用于中压无功补偿装置。并可以方便地扩充应用于分布式电力监控等领域
Abstract:
Based on SCM, sampling- and- holding circuit and general A/D converter, the traditional measurement for electric power parameters has poor precision and real - time capabilities. Briefly analyzed the characters of measuring three - phase electric power parameters , introduced a method of interface between the chip of S3C44B0X with 32 - bit embedded processor of ARM7TDMI and the A/D application- specific chip of ADS7864. The structttre can predigest hardware circuits, relieve the contradiction between the real - time capabilities and precision when sampling data. Based on RTOS, this method of interface can implement expediently such functions as sampiing electric power parameters, software digital filtering, harmonic analysis and so on. It has been applied on an equipment of middle - voltage reactive power compensation, and can be expediently applied in such fields as distributed electric power monitor and control, etc
