Design and Study of a Electrical Power Data Acquisition System Based on DSP

介绍了一种用于电力系统的数据采集系统。该系统采用数字信号处理器 (DSP)和复杂可编程逻辑器件 (CPLD)作为核心芯片 ,给出了主要部分的电路及其原理、功能 ,系统中使用CPLD实现基本逻辑 ,使系统有足够的冗余和灵活性 ,具有可靠性高。

The performance of the data acquisition system is very important in the electrical power system. In the past, most relay protection systems use singlechip as the CPU, but because of its slow computing rate and inadequate internal resources, many algorithms can not be implemented by it. Recently the new generation CPU--digital signal processor begins to be used widely as it has advantages on structure and computing rate. The paper introduces a data acquisition system based on DSP and CPLD, it also presents the circuit diagram and the function of its main part. In this system, the basic logic is implemented by CPLD, so the system not only has enough redundancy and agility, but also can be upgraded.
