In India Power system monitoring is based mainly on measurements provided by Remote Terminal Unit (RTU). For power system measurement synchronized Phasor or Phasor Measurement Unit (PMU) is popular choice in abroad and its popularity is increasing day by day because of its several features. Direct measurement of voltage or current Phasor is possible because of PMU which was not possible earlier...

The phasor measurement unit (PMU) is considered to be one of the most important measuring devices in the future of power systems. The distinction comes from its unique ability to provide synchronized phasor measurements of voltages and currents from widely dispersed locations in an electric power grid. This paper proposes an algorithm based on the clustering techniques for solving the optimal P...

In this paper, phasor measurement unit (PMU) data-based synchronous generator model identification is carried out using unscented Kalman filter (UKF). The identification not only gives the model of a synchronous generator’s swing dynamics, but also gives its turbine-governor model along with the primary and secondary frequency control block models. PMU measurements of active power and voltage m...

This paper aims to optimize the PMU (Phasor Measurement Unit) placement for a full observation of the power network and the minimum number of PMUs. In this paper, competition of Mixed Integer Non-Linear Programming and heuristically algorithms such as Bacterial Foraging Algorithm is presented. The results are demonstrated with PMU placement optimization simulation and a redundancy measurement a...

This paper introduces the uses of Robust Dynamic State Estimation (RDSE) with Phasor Measurement Unit (PMU), The M-Estimators Quadratic Linear (QL) and Square Root (SR) Estimators have been used. For the solution of the M-estimators problem, Iteratively Re-weighted Least Squares Estimation (IRLS) method is applied. In this work, we used the Decoupled Current Measurement (DCM) method to include ...

This paper proposes an optimal allocation of phasor measurement unit (PMU) placement model under controlled islanding of power system such that the power network remains observable under controlled islanding condition in addition to normal operation condition. The optimization objective of proposed model is to reduce the number of installed PMUs by using hybrid optimization algorithm. The objec...

This paper presents a review of the Phasor Measurement Units employed in the Modern Power Systems. Synchronized phasor measurements have advanced the power system monitoring, controlling, protecting and operating standards in the recent decades. Its potential can be used effectively in the process of upgrading the current power grids into smart grids. With these ideas in mind, a review on PMU i...

The standards of power system monitoring, control and protection are elevated by Phasor Measurement Units (PMUs) as an auspicious tool. It is the purpose of this paper to determine the optimal number and locations of PMUs so as to make the system measurement model observable and also estimate the power system state. The proposed modelling approach which models PMU placement as an integer linear...

in this paper, a new method based on branch placement for the optimal positioning of phasor measurement units (pmus) in power systems is proposed. in this method, the pmus are in type of single-channel and are installed at the beginning of the branches. therefore, they are able to measure the bus voltages. also, the installation of the pmus on the branches increases the security of observabilit...

In this paper it is shown that M class PMU (Phasor Measurement Unit) reference model for phasor estimation recommended by the IEEE Standard C37.118.1 with the Amendment 1 is not compliant with the Standard. The reference filter preserves only the limits for TVE (total vector error), and exceeds FE (frequency error) and RFE (rate of frequency error) limits. As a remedy we propose new filters for...
