Application and Streaming of Multiple PMUs in Real-time Digital Simulator

Phasor measurement units (PMUs) play a crucial role in monitoring and analyzing power system dynamics, and their integration into Real-time Digital Simulator (RTDS) environments enables accurate real-time simulation and testing of power systems. Therefore, this paper proposes an experimental setup and a detailed configuration of relevant software to facilitate the streaming of multiple PMUs in RTDS. An experimental setup that facilitates the execution of hundreds of fault scenarios and the acquisition of transient data, is developed with the integration of RTDS, PMU Connection Tester, openPDC, MySQL, and MATLAB. The paper examines the performance and accuracy of the implemented multiple PMU setup through a case study and experimental results of fault location detection (FLD). A convolutional neural network (CNN) is trained with the high-precision transient data gathered using GTNET PMUs for FLD. A modified IEEE-9 bus system integrated with PMUs is taken as a test system for demonstration. The significance of this study is to provide researchers with a detailed configuration for all the necessary software and a reliable framework to stream multiple PMUs in RTDS, store data in an SQL database, and use it for various power system applications.
