Research on automatic detection method of fault information in microcomputer relay protection system

为了解决传统故障信息自动检测方法未进行信息集中采集,而存在故障信息准确接收数量较少、检测准确率低的问题,在传统研究基础上进行了深入分析。通过微机继电保护装置对自身工作进行保护性能分析,发现所需保护数据信息,对所发现的信息进行系统管理,集中采集故障信息,在完成微机继电保护系统故障信息采集后,对其进行初步分析,加大对故障信息的了解程度。经过以上处理的微机继电保护系统进行故障信息自动检测,将主板的测试系统分为主控平台、测试装置俩部分。最后通过实验验证检测方法的有效性,实验结果表明,提出的故障信息自动检测方法能够在短时间内接收到大量故障信息,检测准确率更高。

In order to solve the problem that the traditional fault information automatic detection method does not collect the information in a centralized way,but there is a small number of fault information received accurately and the detection accuracy is low,the traditional research is carried out on the basis of in-depth analysis.Through the protection performance analysis of the microcomputer relay protection device,the required protection data information is found,the discovered information is systematically managed,and the fault information is collected in a centralized way.After the fault information collection of the microcomputer relay protection system is completed,the preliminary analysis is carried out to increase the understanding of the fault information.After the above-mentioned processing of the microcomputer relay protection system for automatic detection of fault information,the main board of the test system is divided into two parts:the main control platform and the test device.The experimental results show that the proposed method can receive a lot of fault information in a short time,and the detection accuracy is higher.
