Active Control Method for Torsional Vibration of DFIG Drive Chain Under Asymmetric Power Grid Fault

IEEE Access, 2020
When the asymmetric fault occurs in power grid, it will cause the oscillation of the electromagnetic torque of the doubly-fed induction generator(DFIG).

Analysis on Circulating Current and Split Capacitor Voltage Balance for Modular Multilevel Converter Based Three-phase Four-wire Split Capacitor DSTATCOM

Journal of Modern Power Systems and Clean Energy, 2021
We propose a modular multilevel converter (MMC) based three-phase four-wire (3P4W) split capacitor distribution static synchronous compensator (DSTATCOM), aiming at compensating unbalanced and reactive load currents.

SEQUENCE OF BINOMIAL COMPONENTS IN ITALIAN AND CROATIAN LANGUAGE [PDF]

Hum, 2018
Unlike other idiomatic classes binomials are composed of two equally valuable elements mostly connected with the conjunction and. In the most European languages, as well as in Italian and Croatian, besides strong idiomaticity, they are mostly marked by ...

Component-by-component construction of shifted Halton sequences

, 2015
We study quasi-Monte Carlo integration in a weighted anchored Sobolev space. As the underlying integration nodes we consider Halton sequences in prime bases $\boldsymbol{p}=(p_1,\ldots,p_s)$ which are shifted with a $\boldsymbol{p}$-adic shift based on $\boldsymbol{p}$-adic arithmetic. The error is studied in the worst-case setting.

MMC-SST input-level control strategy considering power quality optimization

电力工程技术, 2022
The surge of negative sequence component of current affects the waveform quality of grid side current and endangers the normal operation of the system when the three-phase voltage of solid state transformer (SST) in the distribution network is unbalanced

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

Pediatric 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 ...

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.
