继电保护装置自动测试系统的研制及应用

Development of Automatic Testing System for the Protection Devices

国内继电保护装置的测试主要依靠测试人员操作保护测试仪器模拟故障来完成。因此,需要测试人员熟悉保护装置的工作原理,并且熟练操控测试仪器。这种测试方式存在,被测装置与测试仪之间接线复杂,反复操控测试仪工作量大,测试面覆盖不足,测试效率较低,测试用例不易标准化等不足之处。文章设计和研制了一套自动测试系统。该自动测试系统输出模拟量,修改被测装置各项参数及条件,自动完成测试结果比对,生成测试报告,实现真正意义的“一键式”测试。实际应用表明,该系统可以满足继电保护装置的测试需求,具有重要的实用价值。

The test of the protection devices is mainly done manually in China. Manual test requires the professionals to be familiar with the principle of protection deviceas well as revising the connecting wire and relevant parameters during the test, which causes large volume of work with low efficiency and inadequate coverage, so it is difficult to standardize. Therefore, an automatic testing system is developed according to the existing automatic testing system of NARI. The system has superior scalability and compatibility, and could provide adequate channels of analog output, binary input and binary output, so the system could achieve one key testing. Practical application shows that the system can satisfy the test requirements of relay protection device,and has important practical value.
