Monitoring micro phasor measurement units at university campus

This paper presents the results of an ongoing project involving the monitoring of micro phasor measurement units (micro-PMU) at Universidade Federal do Paraná (UFPR). The infrastructure for receiving, processing and storing data from micro-PMUs, energy meters and power quality analysers was deployed. Free software were tested for data storage and visualization. We modified an existing open-source Energy Monitoring System (EMS) for proper use with PMUs. The software native communication protocol was adapted from hypertext protocol (HTTP) to direct reception of user datagram protocol (UDP) in IEEE Std. C37.118.2-2011 format to receive micro-PMUs transmission at 120 phasor per second. We modified data storage format to efficiently deal with time information allowing reduction of 60% of storage space in comparison to commonly used phasor data concentrator (openPDC).
