Hierarchical frequency control strategy of doubly-fed induction diesel generator under emergency condition

open access: yesEnergy Reports, 2022
Natural disasters lead to the uncertain topological structure of the urban distribution network. It is difficult for the communication system to recover quickly, which brings great difficulties to restoring the power supply.

Generator Systems for Marine Current Turbine Applications: A Comparative Study [PDF]

open access: yes, 2014
Emerging technologies for marine current turbines are mainly related to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for marine current turbines. As in the

МЕТОДИ КЕРУВАННЯ ЗАДЛЯ УСУНЕННЯ ГАРМОНІК У СИСТЕМАХ ГЕНЕРУВАННЯ ЕЛЕКТРОЕНЕРГІЇ НА ОСНОВІ МАШИНИ ПОДВІЙНОГО ЖИВЛЕННЯ

open access: yesПраці Інституту електродинаміки Національної академії наук України, 2022
The variable speed power generation system based on a doubly-fed induction generator is the most popular in the wind industry. The stator is connected directly to the mains in such a generator, while the rotor is connected to the mains via a ...

Control and performance of a flywheel energy storage system based on a doubly-fed induction generator-motor for power conditioning [PDF]

open access: yes, 1999
A flywheel energy storage system based on a doubly-fed induction generator-motor basically consists of a wound-rotor induction machine and a cycloconverter or a voltage-source PWM rectifier-inverter which is used as an AC exciter.

The Squirrel-Cage Induction Generator [PDF]

open access: yesTransactions of the American Institute of Electrical Engineers, 1912
A careful examination of the various attributes of the induction generator discloses its appropriateness for certain classes of work. It is the purpose of this paper to describe these attributes and to endeavor to deduce therefrom the correct economic field for such machines.

Local and Remote Voltage and Reactive Power Control in the Presence of Induction Generators [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
Voltage and reactive power control in distribution networks is one of the most basic tasks of a distribution network operator. This is usually controlled by on-load tap-changer (OLTC), substation capacitors, and feeder capacitors.

Inductive MHD Generator

open access: yesZeitschrift für Naturforschung A, 1963
The electrodynamic response of a particular inductive magnetohydrodynamic generator is calculated. Expressions for the output voltage and output power are derived. The results of experiments conducted with the generator mounted on an electromagnetic shock-tube agree with the theoretical predictions. The measured output power is of the order of 10 watts

Sample selection and inductive generalization [PDF]

open access: yesMemory & Cognition, 2009
In two experiments with adults (N = 126), we examined the influence of sampling procedure on inductive generalization. In predicate sampling, participants learned the category identity of individuals known to possess some property. In subject sampling, individuals selected for category identity were discovered to possess a novel property.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
