Technical Report: PMU Analysis
نویسندگان
چکیده
In [4], we have studied the statistical properties and mono-fractality of the power system time series, voltage magnitude (V), frequency (f), and phase angle (θ). The power system data was measured using three Phasor Measurement Units (PMUs) installed at Baylor University, Harris Substation, McDonald Observatory in the Texas Synchrophasor Network [1]. Our analysis of several data sets has shown that the three time series are non-stationary. Moreover, we provided an evidence to the existence of long-range memory in the power system data with scaling exponents higher than 0.5. The scaling exponents of voltage magnitude (V), frequency (f), and phase angle (θ) were approximately equal to 1, 1.5, and 0.7, respectively.

OBJECTIVE To evaluate technical efficiency and potential presence of scale and scope economies in Mexican private medical units (PMU) that will improve management decisions. MATERIALS AND METHODS We used data envelopment analysis methods with inputs and outputs for 2 105 Mexican PMU published in 2010 by the Instituto Nacional de Estadística y Geografía from the "Estadística de Unidades Médica...
متن کاملOptimal PMU Placement Considering with HVDC Links and Their Voltage Stability Requirements
In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network. However, it is not practical in real networks due to the relatively expensive cost of PMUs and other technical limitations. Optimal PMU Placement (OPP) is an optimization p...
متن کاملA Data Driven Framework for Real Time Power System Event Detection and Visualization
Increased adoption and deployment of phasor measurement units (PMU) has provided valuable fine-grained data over the grid. Analysis over these data can provide real-time insight into the health of the grid, thereby improving control over operations. Realizing this data-driven control, however, requires validating, processing and storing massive amounts of PMU data. This paper describes a PMU da...

i ABSTRACT In electric power systems, phasor measurement units (PMUs) are capable of providing synchronized voltage and current phasor measurements which are superior to conventional measurements collected by the supervisory control and data acquisition (SCADA) system in terms of resolution and accuracy. These measurements are known as synchrophasor measurements. Considerable research work has ...

In some recent articles, the spoofing of Phasor measurement unit (PMU) GPS receiver has been highlighted as a threat to power grid protection system. Having spoofed PMU GPS signals, one can manipulate the measurements and inject bad data to power grid protection system. The previous anti spoofing methods are all based on GPS signal analysis. The mentioned methods are just able to detect spoofin...
