The early inter-turn short-circuit fault of field winding (ISFF) occurs between adjacent strands in a single rotor slot, which is significant safety hazard the transient operation large-capacity synchronous condenser. To realize high-precision detection ISFF, this paper proposes characteristics analysis method ISFF with strand as minimum unit. This combines novel stator asymmetric branch connec...

the doubly fed induction generator (dfig) is one of the most popular technologies used in wind power systems. with the growing use of dfigs and increasing power system dependence on them in recent years, protecting of these generators against internal faults is more considered. loss of excitation (loe) event is among the most frequent failures in electric generators. however, loe detection stud...

Synchronization has gained attention in science recently. In electrical engineering, a power network requires generators and loads to be in synchronization. The increase in distributed dc power sources without sophisticated controls has made synchronization more difficult. This paper proposes a synchronous inverter designed for linking distributed power sources within a power network. The linka...

in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

Parameters estimation of dynamic model of synchronous generators is an essential prerequisite for viable and reliable power system operation and offline studies. Advent of phasor measurement units (PMU) and its growing applications in power systems have led to an evolution in the electric power network wide-area monitoring, protection, and control. Alongside, these devices have revealed unprece...

Permanent magnet synchronous generators (PMSG) have a huge potential for direct-drive wind power applications. Therefore, optimal design of these generators is necessary to maximize their efficiency and to reduce their manufacturing cost and total volume. In this paper, an optimal design of a six-phase 3.5 KW direct-drive PMSG to generate electricity for domestic needs is performed. The aim of ...

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...

Quadrature-axis reactance for various reasons comes into account as one of the most important parameters of salient pole synchronous machine. There are several common standard methods for measuring this parameter that also have been explained with some details in the standards, scientific papers and text books. One of these methods is the maximum lagging current test that is done simply at no-l...

In this paper, an optimized double-fed induction generator in wind power plants has been studied. The equations of optimal design is extracted and for evaluation of generator performance, a model has been presented and based on this model, the generator is optimized using finite element analysis (FEA). The aims of the optimizations are improvement of voltage and current waveform to could reach ...
