Design and Application of One Click Automatic Testing for Substation Relay Protection Devices

由于变电站继电保护装置的配置数据与目标测试系统的数据存在不匹配问题,导致测试结果的故障覆盖率较低,测试效果有限。为此,提出变电站继电保护装置一键自动测试设计与应用。根据测试需求,收集与生成配置信息数据,并将文件中的字符串映射为目标系统中的枚举值,对配置数据与测试目标系统的数据进行匹配,结合测试模板的分类、命名规则、存储位置建立测试模板库,从而模拟继电保护故障类型,并构造系统运行状态方程,进而设置故障参数,基于此,测试系统根据模拟的故障类型从云端获取继电保护装置测试方案,执行装置测试方案中测试项目进行自动测试,实现一键式智能化测试。实验结果表明,所提方法测试结果的故障覆盖率较高,总体测试效果更好。

Due to the mismatch between the configuration data of the substation relay protection device and the data of the target testing system,the fault coverage rate of the test results is low,and the testing effect is limited.Therefore,the design and application of one key automatic testing for substation relay protection devices are proposed.According to the testing requirements,collect and generate configuration information data,and map strings in the file to enumeration values in the target system.Match the configuration data with the data of the testing target system,establish a testing template library based on the classification,naming rules,and storage location of the testing template,simulate relay protection fault types,construct system operation state equations,and set fault parameters.Based on this,the testing system obtains the relay protection device testing plan from the cloud based on the simulated fault types,executes automatic testing of the testing items in the device testing plan,and realizes one click intelligent testing.The experimental results show that the proposed method has a higher fault coverage rate and better overall testing performance.
