摘要
为有效地监测大型发电机运行过程中定子绝缘的局部放电,了解定子绝缘的老化状态,基于虚拟仪器技术开发了大型发电机局部放电在线监测系统。对虚拟仪器的概念、系统的软硬件组成、安装方案、功能及其特点进行详细介绍,并给出实验室的测量结果。
In order to monitor the partial discharge in large generator and inspect the insulation condition of stator bar,an on line monitoring system based on virtual instruments technology is developed. This paper describes the idea of virtual instruments, the structure of hardware and software, the functions and characteristics of system, and the scheme of installation in detail. The system is proved to be effective and the result of experiment is also given in the paper.
