Quinlan, Michael Brock 2015-07-22T22:33:45Z 2015-07-22T22:33:45Z 2017-07-23T09:15:24Z 2015-05 2015-04-23 This thesis aims to investigate the production and transmission of synchrophasor data. Synchrophasor data provides near real-time data at widely separated points across the power grid. This data is produced by PMUs, and their ubiquity on the grid is becoming a reality. Commercial PMUs today are proprietary systems which in general do not produce data which is up to what the IEEE standard for synchrophasors dictates. By building a one-phase, open source, distribution level PMU, the inner workings and complications of synchrophasor generation can be understood. Many studies have been performed in the area of PMUs, but this thesis focuses on distribution level measurements and the root causes of erroneous data. The device described produces synchrophasor data from 120 V outlets for the cost of $350. It is based on National Instruments hardware, and contains a backup battery for continuous measurements. The greatest issues in its creation were obtaining high accuracy in the phase measurements and acquiring a reliable network connection to transmit the data. These issues were caused by inherent hardware limitations, software development issues, and networking complications. Using the information from this device can direct further efforts in remedying bad data from synchrophasor measurement units.
