1、摘要变电站自动化和无人值班站是当今电网调度自动化领域的两大热门课题。变电站的运行正从早期的常规保护、人工控制发展到现在的无人值守、远动控制、系统综合自动化。面向对象的综合自动化系统采用全分布式通讯网络，具有功能下放、风险分散、组态灵活简单等特点。但相对于系统结构的发展，监控软件的开发变化依然不大，多采用 C/C+等高级语言编程开发且往往针对某个具体应用开发。因为没有系统性和具有前瞻性的结构框架，该方式缺点明显，如开发周期长、强度大、移植扩展困难。新一代 Windows 平台下的组态软件有广泛的硬件支持、开放性互连、图形界面优美、开发周期短等优点，并且编译后可以达到 C 语言编译后的执行速度。本
2、次毕业设计，主要结合牵引变电所应用系统，研究LabVIEW 在电站远程监控中的开发技术。虚拟仪器提供了易于人机交流的虚拟面板，这些面板可以使我们实现在各个功能模块之间的转换。本设计中，共使用了七个面板，主界面是用来实现登陆功能，登陆之后就会自动跳转到功能选择界面，功能功能选择界面是各个功能模块的连接平台，可以迅速切换到我们想要到达的界面，4 个功能模块分别是工况图、远程监控、波形信号、数据分析。通过不同界面，共同实现对整个系统的监控。【关键词】：LabVIEW；虚拟仪器；远程监控；变电所自动化AbstractSubstation automation and none on duty stat
3、ion are the two hot areas of electric networks control automation .The running of substation has developed from the earlier regular protection to modern model which is controlled by none on duty , remote and complex systematic automation . The complex automation system used the communication network
4、 which is for all terminals have many advantages such as deliver the function to the next, decentralize the risk and configuration convenient and easy.But compared to the development of systematic structure ,the monitoring software has changed little which apply the C and C+ language higher language
5、s and used to some applying development . This method has distinct disadvantages for the structure lack of system and forward view such as long developing term ,many works and hard to deliver.The system software based on new Windows plat has the advantages such as wide hardware sustains, connected o
