Due to numerous advantages of the doubly-fed induction generator (DFIG), the application of DFIG based wind generator (WG) is increasing very rapidly. However, the transient stability is one of the major concerns of the DFIG based wind generator. Therefore to accomplish this goal, in this paper, an existing non-linear controller based new inductive bridge type fault current limiter (NC-NIBFCL) ...

Fault protection is commonly available in most of power management chips to date and its accuracy highly praised, mainly in cases where driving rates reach a few Amperes, or even above. In this paper, some of most common techniques for overcurrent protection (OCP) applied to both switching and linear DC/DC supply voltages are revisited and their trade-offs analyzed. Current limitation approache...

In this work, a steady discrete unified gas kinetic scheme (SDUGKS) is proposed to solve the radiative transfer equation (RTE), which an improvement of original SDUGKS [X. F. Zhou et al., J. Comput. Phys. 423, 109767 (2020)]. The trapezoidal rule other than rectangular used in adopted method reconstruction energy flux across cell interface, just as unsteady DUGKS. By way, length characteristic ...

In this paper performance analysis of Doubly Fed Induction Generator under abnormal condition is analysed. In recent years, this series compensated transmission system will produce unwanted effect of sub synchronous resonance. Super Conducting Magnetic Energy Storage (SMES) provides an efficient damping for sub synchronous resonance that will enhance power system stability in addition to real a...

We have investigated the generation region of intermittent plasma structures, which could be due to blob-like cross field transport around divertor simulation experimental module (D-module) in tandem mirror device GAMMA 10/PDX. A positive skewness ion saturation current was clearly seen when electrode movable probe located at radial edge and just front entrance limiter D-module. Fourier analysi...

This paper summarizes the work done to show finite element modeling results on a high temperature superconductor fault current limiter (FCL). The paper also gives the small mock-up design of the matrix FCL and its finite element model (FEM). It also discusses the limitations of the FEM and explains how the results from the FEM compare with the experimental data derived for the configuration. A ...

a two-variable integrate and fire model is presented to study the role of transient outward potassium currents in producing temporal aspects of dorsal cochlear nucleus (dcn) pyramidal cells with different profiles namely the chopper, the pauser and the buildup. this conductance based model is a reduced version of km-lif model (meng & rinzel, 2010) which captures qualitative firing features of a...

The up-gradation of an Electrical power generation network results in higher levels of short circuit fault current. Thereby, the existing protection equipment like circuit breakers, isolators and fuses become under capacity and not capable of withstanding higher short circuit currents. Thus the system is highly vulnerable to the adverse effects of short circuits. Replacing the whole protection ...

This paper provides an overview of a dynamic analysis carried out on a modified Nordic test system to determine the impact of the Powerformer on voltage stability. The unique aspects of the Powerformer will be highlighted and the modeling of long-term dynamic elements, especially those pertinent to the study of the Powerformer will be discussed. Overexcitation limiter models created for use in ...
