PMU data stream generator for testing of transmission properties in PMU virtual networks

Increasing deniands for quality and reliability of electrical supply with rising complexity of electrical networks put emphasis on possibility to monitor and foresee behavior of these networks. One of the main aims of this monitoring is to prevent events that may cause failure or evcn datnages of the transmission network or the user side. This is the reason why units for synchrophasor measurements getting increased attention these days. Main function of PMU units is to measure and report the network status in predefincd locations. PMU features in terms of evaluation and reporting dcscribe the standard IEEE C37.188. As well as measurement, very important part is also a data transfer to higher systems. This article de- seribes standard IEEE C37.118 in terms of data frames transfer and structure of these frames between PMU and PDC systems. Part of this work also describes PMUGen software which simulate PMU data stream and cnables to study transmission in PMU networks. This software is dcveloped in graphical environment LabVIEW. This software enables creation of virtual PMU units without using of any spccial hardware and will be used as a tool for teaching students interested in this field.
