摘要
介绍了 CPLD技术在变电站 RTU上的应用 .在设计中 ,我们通过将 RTU所有外围数字电路集成到一块芯片上 ,以达到降低硬件复杂程度 ,提高系统的可靠性的目的 .通过对 CPLD的硬件编程 ,采用中断的方法来捕获事件顺序记录 (SOE) .与传统 RTU设备相比 ,在电力系统故障分析中 ,所提供记录信息的准确性得到了提高 .
This paper introduces the application of CPLD in the RTU of transformer substation. The complexity of hardware is mitigated and system stability is improved by integrating system's peripheral digital circuit into a single chip. By means of programming the CPLD, interrupt method is employed to capture the Sequence of Event (SOE). Therefore, compared with the traditional equipments, this RTU can support more accurate information in analyzing the failure of electric power system.
