为了体现智能变电站高度信息化的优势,针对智能化继电保护装置,研究了一套智能变电站继电保护设备自动测试系统。在测试过程中引入信息融合技术,可实现自动更改测试参数、投退软压板以及写控制字,自动获取二次设备的动作信息、判断二次设备响应的正确性并生成符合电力行业要求的综合测试报告,构成完整的闭环测试。应用结果表明,该自动测试系统优化了测试流程,同时提供了新型的非人力所及的测试方法,从而提高了测试的效率和准确度。

Automatic test system of relay protection device for smart substation based on information fusion technology

In order to reflect the advantages of high informatization of smart substation,an automatic test system for relay protection equipment in smart substation is studied for intelligent relay protection device.Information fusion technology is introduced in the test process,which can automatically change test parameters,drop and retreat soft platen and write control words.And it can also automatically obtain the action information of secondary equipment,judge the correctness of secondary equipment response,and generate comprehensive test report meeting the requirements of the power industry,forming a complete closed-loop test.The application results show that the automatic test system optimizes the test process and provides a new test method that is not accessible to human,thus improving the test efficiency and accuracy.
