Research on Automatic Generation and Injection Method of Alarm Data in Smart Substation

Abstract

In order to better standardize the function of intelligent alarm in substation, it needs to be standardized to test it. The existing method of alarm data generation is to manually pick up points. According to the application scenarios of typical faults in substation, the corresponding serialization alarm signals are selected, and the sending order and time interval of the alarm signals are manually configured. This method is not only wastes time and energy, but also easy to make mistakes. In view of the above problems, this paper proposes an automatic generation and injection method for alarm test data in smart substation. Based on the typical fault criterion of intelligent alarm, the fault template file is designed. The test files are automatically generated by a series of options such as lED mapping, alarm basic data mapping, alarm sequence data mapping, and the correction of fault templates, and the test files are loaded into the IED simulation service device. Finally, through the IED simulation device, the serialized warning signals contained in the test files are injected into the integrated monitoring system. The automatic generation and injection method avoids the complex and complicated process of manual pick up and configuration, and realizes automatic testing of intelligent alarm reasoning function.
