摘要以IEC61850为标准建立的数字化变电站，由3个部分即过程层、间隔层、站控层组成。要实现变电站的智能化，需要各种智能装置，它们中的一个就是智能终端。智能终端使用电缆与相应的一次设备相连接，用光纤与二次设备连接，实现了对相关设备相应的功能。建设智能变电站时，构建一次智能化设备，目前最优的办法就是采用智能终端。这种方法是用以前的一次设备结合现在的智能终端实现的，一次设备是它们的基础。智能终端不采用以前的继电器所采用的回路，而是用程序来实现的，这样会节省大量通讯成本。通过GOOSE网络传递命令来控制开关设备，就不容易被干扰。19924

Title Analog design intelligent terminal of substation intelligent based on NI CRIO
Abstract
Intelligent substation IEC61850 standard established part of that process is pided into three layers , the spacer layer , station level . To achieve intelligent substation , requires a variety of smart devices , one of which is the intelligent terminal. Intelligent terminals and the corresponding cable connected to a device , connected with fiber and secondary equipment , related equipment to achieve the corresponding functions . When building intelligent substation , building a smart device , currently the best way is to use intelligent terminals . This method is a combination of intelligent terminals are implemented with the previous primary equipment , the device is a base thereof . Intelligent terminal is not used before the relay circuit used , but with the program to achieve, this will save a lot of communication costs . GOOSE pass commands through the network to control the switching equipment, is not likely to be disturbed. In addition , the intelligent terminal device can also measure the amount of their own state and non- power switching devices , can also achieve self-test, so it is easy for integrated management , protection and control can also be achieved to send and receive commands .
CompactRIO is an embedded control and acquisition hardware platforms , to provide the required performance and high reliability, and flexibility for customized industrial and embedded control applications. CompactRIO embedded systems using PowerPC processor with 10/100M Ethernet ports, serial ports , USB ports and other interfaces , the composition can be easily distributed systems. There are a thousand kinds of built- Labview function can be used to create multi-threaded embedded systems, so that it has real-time control , analysis, and other data recording and communication functions.
This paper analyzes the basic principle of transmission line protection . Write a program to simulate the use of Labview GOOSE message parsing , simulated intelligent substation intelligent terminal basic functions.
