Panel Abstract: Waveform measurement units (WMUs) are an emerging class of smart grid synchronized measurement technologies that provide synchronized measurements for voltage and current waveforms. Since WMUs provide synchronized waveform measurements, as opposed to synchronized phasor measurements that are provided by phasor measurement units (PMUs), the data from WMUs is much more granular than the data from PMUs. This calls for fundamentally new methodologies to analyze WMU data. In this panel, we cover the advancements in this field, in various areas, including sensor technologies, data collection and compression, data analytics, and use cases. The speakers on the proposed panel are experts in this field with diverse representations, coming from academia, industry, and government.

Title of presentation: Applications of Synchronized Waveform Data to Power System and Apparatus Monitoring
Abstract: Voltage and current waveforms contain the most authentic and granular information on the behaviors of power systems. In recent years, it has become possible to synchronize waveform data measured from different locations of a power system. Thus, large-scale coordinated analyses of multiple waveforms over a wide area are within our reach. This presentation provides an overview on the developments in this fascinating direction and proposes three platforms for applying the data. It further presents several strategies to discover and develop synchronized waveform-based applications for both power system and power apparatus monitoring.

Title of presentation: Synchro-Waveforms in Power Distribution Systems: Field Data, Data-Analytics, and Innovative Use Cases
Abstract: Synchronized waveform measurements, a.k.a, synchro-waveforms, provide the ultimate measurement resolution for voltage and current in advanced power system monitoring. Analysis of synchrophasors has important applications in power distribution systems, such as to detect, identify, and locate incipient faults in power distribution systems. In this talk, we start by looking at a few examples of real-world waveform and synchro-waveform measurements in power distribution systems. We will then discuss some recent advancements in data-driven methodologies in this field, covering both model-based and model-free methods, as we as emerging and future use cases for synchro-wavform measurements.

Title of presentation: Applications of wide-area synchronised waveform measurements
Abstract: Fundamental changes in power grids due to decarbonisation require advanced monitoring and automated analysis. Synchronised waveform data from voltage and current sensors offers several new capabilities beyond synchrophasors from Phasor Measurement Units (PMUs). This presentation will describe new applications which are enabled by this approach, including: deeper classification of events (e.g., for root cause identification for electrical faults), detailed wide-area power quality investigations, and post-event analysis of major system-wide disturbances. However, the obvious drawbacks in manipulating, transferring, and storing waveform data are the high data bandwidth and storage requirements. This presentation also reports on a platform to address these issues by using a high-performance lossless data compression method designed for streaming waveform data, which significantly reduces data bandwidth requirements and improves end-to-end efficiency and latency. An implementation of the scheme, called Slipstream, has been open sourced to enable industry adoption (available at https://github.com/synaptecltd/slipstream). The presentation will demonstrate the performance of the data compression method, which removes the barriers for utilities to stream, record, and analyse synchronised power system waveform data.

Title of presentation: Challenges and their potential solutions in implementing synchronized waveform applications
Abstract: This presentation will discuss several procedures that enable the successful application of synchronized waveform measurements. These procedures aim at improving the data quality of the synchronized measurements before they are utilized in the desired applications; for example, it is not uncommon to encounter datasets where the phase ordering of the voltage measurements and/or the polarity of the current measurements are inconsistent among the measurement locations due to improper connection of the measurement devices. Further, an algorithm for detecting abnormal/novel waveforms within large synchronized waveform datasets is presented. Finally, we will illustrate how inaccurate timestamps in the synchronized waveform measurements affect some applications.
