Phasor measurement units (PMUs) are a key part of electrical power systems, providing the dynamic monitoring and control impacting overall operation synchronization network if not properly designed. This paper investigates use phase-locked loop (PLL)-based algorithm for PMUs (to accurately find magnitude, phase, frequency) in three-phase system. Various PLLs reported literature, ranging from ve...

This paper presents a critical survey on different application of Phasor Measurement Units (PMUs) in electric power system networks incorporated with FACTS controllers for advanced power system operations, monitoring, control, and protection.

Sensors like current transformers and voltage transformers are used to monitor the power systems and data from these sensors are collected in appropriate computer applications to observe the state of the power system. Phasor Measurement Units (PMUs) get data from current and voltage transformers and time-stamp them thereby paving the way for wide-area monitoring of the power system. In wide-are...

This paper presents analytical tools aimed at improving and simplifying the development of frequency-controlled dimming electronic ballasts. A modified phasor transformation is proposed that converts a frequency-modulated signal into an equivalent time-varying phasor. The proposed transformation is applied to develop a complete small-signal phasor model of the LCC resonant ballast, which explic...

The need for Phasor Measurement Units (PMUs) is rising as renewable energy sources become more prevalent in power networks since the rate of change frequency being deteriorated. Appropriate and accurate network measurements are a requirement precise monitoring control system. This paper presents low-cost PMU development, so-called PhasorsCatcher, networks, using sufficient but straightforward m...

Limited data feedback rate, e.g. 1-10 samples per second instead of 25-60, causes adverse effect on wide-area damping control (WADC). An observer driven system copy (OSC) approach is suggested here to deal with low data rates. The basic idea is to use the knowledge of nominal system dynamics to approximate the actual system behavior during intervals when data from phasor measurement units (PMUs...

Abstract—This paper presents a Generalized Binary Integer Linear Programming (GBILP) method for optimal allocation of Phasor Measurement Units (PMUs) and to generate Dynamic State Estimation (DSE) solution with complete observability. The GBILP method is formulated with Zero Injection Bus (ZIB) constraints to reduce the number of locations for placement of PMUs in the case of normal and single ...

This paper presents a new methodology for correcting gross errors in power distri- bution systems state estimation (SE). A SE algorithm is developed based on the Weighted Least Squares (WLS) using hybrid approach which non-synchronized measurements and PMUs (Phasor Measurement Units) are used together. At end of process, Normalized Residuals (NRs) calculated each measurement existence detected ...

Voltage instability is a crucial issue in the secure operation of power grids. Several methods for voltage stability assessment were presented. Some of them are highly computationally intensive, while others are reported not to work properly under all circumstances. This paper proposes a new methodology based on the generator equivalent circuit model (GECM) and the phasor measurement unit (PMU)...
