Similar large signal synchronizing instability that is common in traditional power system also exists voltage source converter (VSC) dominated system, which increasingly reported and investigated. In this paper, the of phase locked loop (PLL) synchronized VSC connected to weak ac grid First, influence high impedance on PLL's dynamics explored an additional feedback found be introduced, deteriorates performance PLL. Then analysis model similar as rotor motion synchronous generator (SG)...
Instability issues of the grid-connected doubly fed induction generator (DFIG) based wind turbines (WTs) during low-voltage ride-through (LVRT) have got little attention yet. In this paper, small-signal behavior DFIG WTs attached to weak ac grid with high impedances period LVRT is investigated, special paid rotor-side converter. First, on studied strategy, influence high-impedance summarized as interaction between phase-looked loop (PLL) and rotor current controller (RCC). As modal analysis...
Instability phenomenon of type-4 wind turbine during grid faults is increasingly concerned by researchers and may result in failure low-voltage ride through (LVRT), especially when connected to a high-impedance ac grid. In order carry out the stability analysis for turbines deep voltage sag, dynamic model, which reflects interaction between phase locked loop (PLL) alternating current control (ACC), first developed. Eigenvalues modal show that there risk pair poorly damped poles become...
With the increasing penetration of renewable energy generation, grid-forming (GFM) converters that simulate dynamics synchronous generator (SG) and actively participate in grid voltage frequency regulation are increasingly employed. In GFM converter dominated power system, similar transient synchronization stability is common conventional system also exists, which closely related with control converters. this paper, virtual (VSG) focused on, influence switched operation mode (TSOM)...
Myocardial infarction (MI) remains the leading cause of morbidity and mortality worldwide, novel therapeutic targets still need to be investigated alleviate myocardial injury ensuing maladaptive cardiac remodelling. Accumulating studies have indicated that lncRNA H19 might exert a crucial regulatory effect on cardiovascular disease. In this study, we aimed explore biological function molecular mechanism in MI. To investigate functions H19, miRNA-22-3p KDM3A, gain- loss-of-function...
Background/Aims: Glioma is one of the most devasting tumors and confers dismal prognosis. Long noncoding RNAs(lncRNAs) have emerged as important regulators in various including glioma. A classic lncRNA-H19, which found to be highly expressed human glioma tissues cell lines, associated with tumor progression thus predicating clinical outcomes patients. However, overall biological functions their mechanism H19 are not fully understood. Methods: Firstly, we analyzed alterations different grades...
In this article, the synchronizing dynamic issue of VSC dominated power system is focused on. First, based on discovered analogous dynamical process (voltage source converter) and SG (synchronous generator), dynamics VSC's PLL (phase locked loop) modeled in similar form SG's rotor motion. The influence control interaction same way as that Then analogized model PLL-based developed. Based proposed model, analysis idea jointing accelerating-decelerating area method numerical simulation employed...
Summary Recent studies showing the therapeutic effect of young blood on aging‐associated deterioration organs point to as solution for clinical problems related old age. Given that defective autophagy has been implicated in aging and organ injuries, this study was designed determine aging‐induced alterations hepatic function underlying mechanisms, with a focus autophagy. Aged rats (22 months) were treated pooled plasma (1 ml, intravenously) collected from (3 or aged three times per week 4...
AISI 420 martensitic stainless steel with excellent corrosion resistance is an ideal choice for plastic injection molds. However, molds are easy to fail in high–intensity and high-pressure environments. Therefore, it's necessary improve their hardness tensile strength prolong the service life of In this work, Selective laser melting (SLM), additive manufacturing technology was utilized process 5 wt% TiC/AISI composites. The influence volumetric energy density (η) on relative density,...
Low retention of endothelial progenitor cells (EPCs) in the infarct area has been suggested to be responsible for poor clinical efficacy EPC therapy myocardial infarction (MI). This study aimed evaluate whether magnetized EPCs guided through an external magnetic field could augment aggregation ischemia area, thereby enhancing therapeutic efficacy. from male rats were isolated and labeled with silica-coated iron oxide nanoparticles form EPCs. Then, proliferation, migration, vascularization,...
Abstract Atherosclerosis (AS) is a prevalent chronic inflammatory vascular disease. Upregulated oxidized low‐density lipoprotein (ox‐LDL) in the serum has been found to induce endothelial cells (ECs) apoptosis by increasing oxidative stress and promoting response, which are essential mechanisms of AS development. Mesenchymal stem (MSCs), secrete exosomes transport microRNAs (miRNAs) regulate cell functions, have become research focus recent years. The results this study manifested that...
Ischemic stroke has extremely high mortality and disability rates worldwide. miR-204-5p been reported to be associated with neurological diseases. However, the relationship linking ischemic its molecular mechanism remain unclear. Herein, we found that expression of was significantly decreased while EphA4 increased in vivo vitro, which reached peak at 24 h after cerebral ischemia/reperfusion. Then, altered rats by cerebroventricular injection. Our study showed overexpression obviously reduced...
This paper unfolds the issue of synchronizing stability in doubly fed induction generator (DFIG)-based wind turbines when connected to weak AC grid. In grid, turbine's terminal voltage vector (both amplitude and phase angle) is significantly influenced by vectors grid DFIG's internal potential that contributed both stator grid-side converter (GSC). Currently, most developed DFIGs synchronize with locked loop (PLL) which generates angle detecting voltage. The complex dynamics may deteriorate...
Vascular smooth muscle cells (VSMCs) are known to undergo functional changes that contribute the pathogenesis of atherosclerosis and restenosis. Wnts a family secreted glycoproteins bind transmembrane Frizzled receptors initiate signaling cascades with indispensable roles during cell migration, adhesion, proliferation, survival.
