The OpenPMU Project: Challenges and perspectives

The OpenPMU project is a platform for the development of Synchrophasor measurement technology, Phasor Measurement Units (PMU), in an open source manner. The project has now been operating for a number of years and has seen increased adoption at Universities and interest from electrical utilities. The OpenPMU device has recently been tested against the IEEE C37.118 standard and shown to operate within the specification. This paper discusses the OpenPMU project from the perspective of the past two years of experience and evaluates successes and opportunities for improvements in both the OpenPMU device and the philosophy of the design.
