Real-time data mediation for synchrophasor application development compliant with IEEE C37.118.2

This paper presents the design and implementation of a IEEE C37.118-2-compliant real-time data mediator, namely BableFish (BF), that facilitates synchrophasor data-manipulation for smart grid applications. The mediator is scalable by virtue of its modular software architecture, and is capable of receiving concurrently synchrophasor data streams from either Phasor Measurement Units (PMUs) or Phasor Data Concentrators (PDCs). The different modules of the mediator and their functional capabilities are discussed. Furthermore, the performance of the mediator is analyzed through several statistical performance stress tests. The mediator facilitates prototyping of wide area power system monitoring and control applications using real-time hardware-in-the-loop simulation, as illustrated with examples in development at KTH SmarTS Lab. Finally, the technical challenges associated with implementation and integration of system-wide synchrophasor solutions for realtime synchrophasor-based applications is discussed.
