Open-Source Framework for Data Storage and Visualization of Real-Time Experiments: Preprint

Research output: Contribution to conferencePaper


Digital real-time simulators (DRTS) are increasingly being used for evaluation of power hardware and controller hardware in the laboratory prior to field deployment. While the digital real-time simulators are capable of simulating large models in real-time, it is challenging to visualize the results of large models without overdraw or confounding the viewer. This paper provides an open source framework for users to visualize their DRTS based hardware-in-the-loop experimental results in real time. This framework could be used by almost all experiments that push data through a network. There are three main components in this proposed framework. First, the digital real-time simulator that pushes the data to a relay. Second, the application that serves multiple purposes, from data storage, testing, and translation of the data to a publisher/subscriber protocol. Finally, the application and libraries that can be used to visualize the data by subscribing to the relay. This framework is available in the open source. This framework is tested using the HIL platform developed for testing the advanced distribution management systems.
