针对电铁广域保护的智能测试系统设计研究

Design and Research of Intelligent Test System for Wide-area Protection of Electrified Railway

随着智能化变电所的发展,继电保护的发展更倾向于依靠装置互联组成网络进行综合判别。本文介绍了一种电气化铁路牵引变电所广域保护智能测试系统,该测试系统能够根据需求控制被测装置的模拟量输出,将被测装置的动作节点接入测试系统的开入模块,以便完成被测装置与测试系统的闭环连接。用户根据装置的功能自行设计测试模板,在模板设计完成后,系统能够逐条地对测试项目进行试验并记录被测装置的动作情况,形成测试报告。该测试系统自动化程度较高,并且能较为准确完成广域保护选跳功能与测距功能的测试。

With the development of intelligent substations,the development of relay protection relies more on the interconnection of devices to form a network for comprehensive judgment.The paper introduces an intelligent test system for wide-area protection of traction substation of electrified railway.The test system can control the analog output of the device under test according to the demand,and connect the action node of the device under test to the input module of the test system,so as to complete the closed-loop connection between the device under test and the test system.The user designs the test template according to the function of the device.After the template design is completed,the system can test the test items item by item,record the action of the device under test,and form a test report.The test system has a high degree of automation,and can accurately complete the test of the wide area protection tripping function and ranging function.
