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...

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 concept of phasor measurement and its application in power system monitoring and control are introduced in this paper. The example of application of PMU in a Campus Wide Area Monitoring System (WAMS) is then elaborated. With the availability of synchrophasor data measurement, it makes possible to establish the power system monitoring by directly employing spectral analysis of power or phase...

Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...

state estimation is the foundation of any control and decision making in power networks. the first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. this paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...

this paper presents the application of the matching pursuit method to model synchronous generator. this method is useful for online analysis. in the proposed method, the field voltage is considered as input signal, while the terminal voltage and active power of the generator are output signals. usually, the difference equation with a second degree polynomial structure is used to estimate the co...
