This paper deals with an improved use of phasor measurements. In particular, the paper focuses on the development of a technique for estimation of generator rotor angle and speed, based on phasor measurement units, for transient stability assessment and control in real-time. Two multilayered feed-forward artificial neural networks are used for this purpose. One for the estimation of rotor angle...

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...

Synchronized phasor measurement systems are being widely used around the world and have become essential elements in evolution of operation large electrical power (EPS). These systems, called Phasor Measurement Units (PMUs), capable recording communicating dynamic data from EPSs a synchronized way by GPS with high sampling rate, generate huge set that, among many applications, has capacity to d...

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, frequency oscillation has been present as it is an important issue in power systems, especially when joined to the new trend use alternative energies energy source, well be a big risk for inter-connection of modern electric networks. Wind farm acts and connected two buses on Iraqi system. Because low-frequency monitoring needs accurate fast, main objective propose novel online sy...

—Efficient power system stability monitoring plays a vital role in recent electric grid technologies. It supports operators at control centers to reduce overloading on weak elements and prevent from collapse. In this paper Phasor Measurement Units (PMUs) technology has been used for real-time measurements that can obtain fast accurate data samples the network. The responses during steady state ...
