“…The first architecture was the first used because uniform sampling simplifies the acquisition process and the signal processing tasks. Previous works are dedicated to exploring and improving uniform sampling methodologies, presented in [4], [5], [9], [10], [11] and [12]. Since uniform sampling is well described in the literature, it will be the main architecture to be explored in this paper.…”

Abstract-The use of Phasor Measurement Unit (PMU) data in power system operation is of practical importance. These data are currently used for real-time operation monitoring and offline analysis. Understanding of the mechanisms involved in the phasor estimation process is necessary for correct phasor data interpretation and analysis, as well as for design of advanced control and protection schemes. In this paper the main phenomena involved in the phasor measurement process are illustrated using a MATLAB based PMU simulator.Index Terms-PMU, phasor data processing, power system analysis, phasor estimation algorithms.

“…From the first published work [13], a few papers have been published regarding it [11]; and some US patents are found in [14] [15]. The main technical issue is to relate the time-tag given by the GPS clock to the sampling clock generated by the local power system frequency measurement.…”

“…Moreover, the application of PMUs to monitor slow electromechanical transients, characterized by nonnegligible deviations from the nominal frequency, could involve, as discussed in [13], [17], and [18], 1 an important misestimation of the synchrophasor phases and frequencies and calls for the following three additional requirements [18]:…”

Abstract-The paper describes the performances of a phasor measurement unit (PMU) prototype based on a synchrophasor estimation algorithm conceived for the monitoring of active distribution networks, as well as its experimental application during some intentional islanding and reconnection tests of an urban medium voltage power network. With respect to typical applications in transmission networks, the use of PMUs in distribution networks requires very low values of total vector error (TVE), which involves particular low values of phase errors of the synchrophasor estimates. These requirements are met by a specifically developed PMU, the characteristics and experimental characterization of which are illustrated in the paper. Three of these PMUs have been then used to monitor experimental tests carried out to assess the capability of a urban distribution network to operate autonomously when fed by a local 80 MW combined-cycle power plant. The information provided by the installed PMUs significantly facilitate the operator maneuvers and appear to be useful for the development of an improved control and management system of the active distribution network.Index Terms-Active distribution networks, islanding maneuver, phasor measurement unit (PMU), synchrophasor uncertainties.

“…The use of high-accuracy measurements and reliable protective algorithms with adequately high-accuracy and prompt decision-making [21][22][23][24][25][26][27][28] should guarantee an effective operation and protection of the electric power systems (EPS) from the consequences of disturbances also in the power system area characterized by changeable operation frequency over a wide range. The adaptation of measurement and protective algorithms in cases under consideration has the frequency nature, i.e., it concentrates on such a change of the parameters of algorithm operation which guarantees the proper estimation of measurement and criterion values by changeable frequency of the input measurement signals: currents and voltages received from the primary circuit [22][23].…”

“…The measurement and protective algorithms used at present in the measurement-protection devices tend to be defined for the constant frequency 50/60 Hz of the input signal, and from the point of view of the synchronous measurement standard requirements, they are characterized by too big inaccuracies when the frequency of the input signals varies over a wide range [21][22]. Another problem for the formulation of the measurement algorithms is the determination of the level of the insensitivity of these algorithms to the existence of interfering components in the input signals ( [22,25,27]). Several interfering components and factors can occur especially in the input measurement signals during the faults within the EPS ( [14-15, 22, 25, 27]).…”

The ongoing evolution of electric power systems (EPS), especially distribution systems within the EPS structure, is driven by the implementation of the smart grid framework. This requires new approaches and technologies to continue ensuring a reliable and secure supply to end users. Fluctuating output from solar photovoltaic and wind plants can cause voltage and power variations in the feeders. In the power grid framework, phasor measurement units (PMUs) are recognized to be an invaluable aid in ensuring the secure operation and stability of transmission systems. The synchrophasor technique requires a high-accuracy time stamping of all the measurements within the analyzed power system area. It must be emphasized that the harmonic injection from power electronic components such as fluorescent lighting, computers, and power inverters of motors and generators can increase total harmonic distortion (THD) levels on distribution feeders and modify the conventional patterns of voltage and current signals. Therefore, what is vital for the functional reliability of synchronous measurements is the implementation of measurement algorithms, which can realize high-accuracy measurements, both in quasi-static and dynamic EPS operating conditions. This article presents the results of software simulations and hardware tests of measurement algorithms that meet the requirements of the IEEE C37.118™-2011 Standard.
