【Abstract】 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.更多还原
