基于测试信息辅助分析的数字化继电保护自动测试方案研究

摘要:

为提高数字式继电保护测试效率，基于对测试信息进行分析诊断，提出一种数字化继电保护自动化测试方 案。该方案可对保护装置进行全面性测试，并考虑测试过程中经常出现的异常情况。通过 MMS 服务实时读取测试 信息并修改保护定值、压板、控制字，对 SV、GOOSE、装置自检、告警、保护动作、装置状态等测试信息充分利用，辅助测 试人员及时发现问题，减少处理问题的时间，提高测试效率。智能变电站采用 IEC 61850 标准以及继电保护信息规范 统一，使得该方案适用于不同厂家的数字式继电保护装置。通过对数字化继电保护测试中常见告警的分析，表明该 方案可有效辅助测试人员处理测试过程中遇到的异常情况。

Abstract:

In order to improve the test efficiency of digital relay protection，an automatic test scheme of digital relay protection is proposed based on test information aided analysis． The proposed scheme can test protection device comprehensively，and consider abnormal situation that appears frequently during the test． Ｒeading test information and modifying protection setting， plate and control character in real time can be realized by MMS service． Test information such as SV，GOOSE，device self － checking，warning，protection action，etc can be fully used to assist testers to identify and solve the problem timely，which improves the test efficiency． Smart substation applies IEC 61850 standard，and the relay protection information is standardized and unified，both of which makes the proposed scheme be applicable for digital relay protection devices from different manufacturers． The analysis of common warning in digital relay protection test shows that the proposed scheme can effectively assist testers to handle the abnormal situation encountered during the test．
