Implement And Research Of Embedded System In Feeder Terminal Unit

In this paper, China's distribution network characteristics,feeder automation technology and the implement of Embedded Technology in Distribution Automation System Terminal Unit are deeply studied. The article's use of the embedded processor speed, ability and resources to addressing the rich, and so on the merits of the design based on the LPC2138 intelligent feeder terminal automation hardware, the use of embedded operating systemμC/OS-Ⅱmulti-tasking capabilities, modules can be cut capacity The corresponding software is designed to achieve the FTU major software functions, the completion of remote measurement, teleindication, failure to judge and deal with, and fast and accurate positioning of the section of the fault, and the use of GPRS communication module achieved a master of the FTU and communications functions. Finally, the FTU where harsh environment typical of the interference of the mechanism and characteristics of the spectrum, some take the necessary measures to improve the anti-FTU the reliability of the experiment conducted in the laboratory and test results show that the Development of the FTU had met the requirements.
