Research of the Relay Characteristics Experimental System Based on Virtual Instrument

基于LabVIEW设计了电流继电器特性实验系统。通过文件读取、数据索引等设计,实现了网络系统的通用性和扩展性。三段式保护实验中自主故障点的设置,实现了限时电流速断保护和定时限过电流保护,并且模拟显示各分段保护区之间动作的延迟效果。网络实验功能的研究为继电保护实验提供了新的实验方法。Flash播放器等在线帮助功能的设计为用户提供了多角度理解继电器工作原理的手段。该实验系统为进行设计性实验提供了平台。

The relay characteristic experimental system is designed by means of Lab VIEW. The versatility and scalability of the system is realized through the documents read and data indexed. The time delay instantaneous overcurrent protection, the definite time overcurrent protection, and the delay effect which simulation display each sectional protected areas＇ movements are all realized by setting automatic fault points in the three -step protective experiment. The research of network experiment function provides a new experimental method for the protective relay experiment. The design of flash player and other on - line help functions provide the means of multi - angle understand relay principle for users. Therefore, the experiment system provides a platform of designing experiment.
