Wind-driven permanent magnet synchronous generators connected to a power grid: Existing perspective and future aspects

Wind Engineering : The International Journal of Wind Power, 2021
Scholars are motivated to work in the field of renewable energy systems (RESs) especially on grid-connected wind generators because of the exciting and noticeable developments going on in this area.

Adaptive Control of a Synchronous Generator

IFAC Proceedings Volumes, 1983
Abstract Theoretical aspects are based on PARK's equations while the experimental part is achieved from on-line machine frequency responses on small signals for different active or reactive powers. The concordant results show that a third order multi-input-multi-output non minimum phase system characterizes correctly the dynamic behaviour of the ...

A generalized frame synchronizer

[Conference Record] GLOBECOM '92 - Communications for Global Users: IEEE, 2003
A modification of the class of frame synchronizers which maximize a likelihood function is proposed. If the stage following the frame sync unit is able to distinguish incorrect from correct syncs, then supplying several alternative frame starting positions effectively improves the synchronization performance.

Generalized synchronization languages

1999
Generalized synchronization languages are a model used to describe the behaviors of distributed applications whose synchronization constraints are expressed by generalized synchronization expressions -- an extension of synchronization expressions. Generalized synchronization languages were conjectured by Salomaa and Yu to be characterized by a semi ...

Finitely Generated Synchronizing Automata

2009
A synchronizing word w for a given synchronizing DFA is called minimal if no proper prefix or suffix of w is synchronizing. We characterize the class of synchronizing automata having finite language of minimal synchronizing words (such automata are called finitely generated ).

Generalized synchronization versus phase synchronization

Physical Review E, 2000
The relation between generalized synchronization and phase synchronization is investigated. It was claimed that generalized synchronization always leads to phase synchronization, and phase synchronization is a weaker form than generalized synchronization.

A Relay Logic for Total and Partial Loss of Excitation Protection in Synchronous Generators

IEEE Transactions on Power Delivery, 2020
Loss of Excitation (LOE) is an important fault in synchronous generators which may cause the generator outage due to out-of-step(OS) conditions. Since the LOE protective relays act based on the impedance or admittance measurement at the generator ...

Synchronous Starting of Generator and Motor

Transactions of the American Institute of Electrical Engineers, 1945
A SYNCHRONOUS motor, generator, or condenser can be started from rest, by means of shaft torque, induction-motor (amortisseur winding) torque, or synchronizing torque. This paper presents data on the last method of starting. The system studied consists of a prime mover driving a synchronous generator, and a synchronous machine driven electrically by ...

On generalized synchronization of spatial chaos

Chaos, Solitons & Fractals, 2003
Here, a generalized synchronization of two spatially chaotic systems is investigated. At the same time, the range of the coupling coefficient in generalized synchronization is also determined analytically. These results thus extend generalized chaos synchronization from temporal systems to spatial systems.

Generalized Synchronization in Chaotic Systems

Chaos, Solitons & Fractals, 1998
Let there be a drive system \(dx/dt=f(x), \;x\in \mathbb{R}^n\), and a function \(H: \mathbb{R}^n \rightarrow \mathbb{R}^m\). The goal is to construct a response system \(dy/dt = g(u(x),y)\) with the drive function \(u\) such that \(||y(t, y_0) - H(x(t,x_0))||\rightarrow 0\) as \(t \rightarrow \infty\) (generalized synchronization).
