基于功能相关性的智能变电站二次系统功能测试验证方法

针对现有智能变电站二次系统功能测试结果仅通过观测二次设备行为得到,而未考虑设备行为背后的信息流程导致的被测功能正确性的误评估问题,该文利用分支流树建立能够反映功能与信息流关联关系的二次系统功能相关性模型,并以功能测试过程中的相关报文为触发条件,通过功能相关性模型与被测功能产生的信息对比进行被测功能正确性判断。通过自动布局算法完成测试过程中相关设备、链路、信息以及测试结果的展示。最后,通过在某220 kV智能变电站进行试验,证明该方法在测试环节中对功能正确性验证的有效性。

Functional testing and evaluation method for secondary system of smart substation based on functional relevance

Aiming at the problem that the results of existing smart substation secondary system function test can only be obtained by observing the behavior of secondary equipment,but ignoring the information flow behind the device behavior.This situation may lead to incorrect evaluation of the correctness of functional test results.This paper establishes a secondary system functional correlation model which can reflect the relationship between function and information flow by using branch tree,and takes the relevant message in the process of functional testing as trigger condition,and judges the correctness of the tested function by comparing the functional correlation model with the information generated by the tested function.The display of related equipment,links,information and test results in the testing process is completed by automatic placement algorithm.Finally,the validity of the method is proved by the test in a 220 kV intelligent substation.
