摘要
随着我国经济的迅猛发展,生活用电以及企业用电量快速增长。变电站母线作为传输电能的方式之一,其可靠性不容忽视。在设计、制备、安装、和运行环境等多种因素的影响下,变电站母线接头在长期运行过程中不可避免会发生损坏,由变电站母线带来的停电事故呈逐年上升的情况,是电网安全运行的重要隐患之一,研究开发可靠的变电站母线接头放电发热故障监测装置是解决问题的关键。本文结合我国现阶段变电站母线接头发热故障特征,进行了硬件软件的设计,并提出了一套能够降低误报率且损耗较低的母线接头节点放电故障监测系统,希望能够为变电站母线的安全可靠运行提供有力保障。
In recent years,with the continuous and rapid growth of China’s economy,the demand for electricity for living and enterprises is increasing.As one of the ways of electric power transmission,the reliability of substation bus can not be ignored.Substation busbar joint in the process of long-term operation in their own quality and running environment under the influence of many factors,such as inevitable damage happens,blackout accident caused by the substation busbar rises year by year,is one of the important hidden trouble of safety of power grid,the research and development and reliable discharge heating substation busbar joint fault monitoring device is the key to solve the problem.In this paper,combined with the characteristics of substation bus joint heating fault at present,the design of hardware and software,and put forward a set of bus joint node discharge fault monitoring system that can reduce the false positive rate and low loss,hoping to provide a strong guarantee for the safe and reliable operation of substation bus.
