摘要
介绍了基于虚拟仪器技术的变压器在线监测系统的软件结构及各个功能模块的实现方法。论述了利用Labview在Windows操作系统下,如何实现系统数据采集、实时数据高速存储、数据库管理、多虚拟示波器界面及游标等核心功能。开发的系统实时性强、界面友好、数据管理方便、操作灵活。实践证明,虚拟仪器技术应用于变压器在线监测系统软件中,开发效率高、系统功能强、维护性好、便于扩展。
In the light of the drawback that exists in the regularly overhaul of currently generally adopted power transformer, the online monitoring system of power transformer is developed based on the virtual instrument technology, the prevision in advance of transformer condition is realized. The paper introduces the key technology about using Labview under Windows operating system to realize the functions of data acquisition, store real-time data at high speed, database administration, multi-oscillograph interface and cursor etc. The system has good characteristics of real-time, friendly interface and convenient in operation. Practice shows that using the virtual instrument technology the transformer condition monitoring system can be developed in high efficiency, the system developed has a strong function and can be maintained and expanded conveniently.
