Wind turbines (WTs) are prone to transient instability during weak grid faults, which is caused by their complex interactions. However, it a challenge analyze the stability, due high-order and strong nonlinearity. Moreover, existing works mainly focus on phase-locked loop (PLL) system while ignoring current control, cannot fully reflect mechanism. To fill this gap, article studies stability of type-3 WT considering both PLL control. First, simplify full model WT, slow–fast subsystem...
Betatrophin, a novel hormone, is correlated with insulin resistance and promotes pancreatic β-cell growth in mice. The aim of this study was to determine circulating betatrophin levels overweight or obese children adolescents.The following pairs subjects were included: (i) normal-weight healthy (n = 27) 28); (ii) non-insulin-resistant 25) insulin-resistant 15); (iii) males 18) females 20); (4) 5 8 yr olds 20) 14 18). Circulating measured using enzyme-linked immunosorbent assay (ELISA). In...
For grid-connected voltage source converters (VSCs),the transient instability in dc-link control timescale threatens the dc capacitor safety and grid stable operation. However, stability analysis presents great challenges, due to high-order nonlinear coupling characteristics of VSC. Existing studies mainly consider single loop reduce order simplify analysis, failing fully reveal mechanism. To cope with it, this paper develops a reduced-order model based on singular perturbation, fourth-order...
For doubly-fed induction generator (DFIG)-based wind turbines (WTs), various advanced control schemes have been proposed to achieve the low voltage ride through (LVRT) capability, whose parameters design is significantly reliant on rotor electromotive force (EMF) of DFIG-based WTs. However, influence current EMF usually ignored in existing studies, which cannot fully reflect transient characteristics EMF. To tackle with this issue, study presents a comprehensive and quantitative analysis...
With the development of renewable energy generation technologies, line-commutated-converter based high voltage direct current (LCC-HVDC) presents characteristics a weak AC system at sending end, which has certain negative impact on small-signal stability LCC-HVDC system. In order to analysis under end and factors affecting stability, small signal model is built by state space model. Based this, effects strength, phase-locked loop (PLL) DC controller parameters performance are analyzed. The...
To investigate the relationship between zinc finger protein(ZFP580)and ventricular remodeling after myocardial is-chemia/reperfusion(I/R) injury in rats.Seventy-two rats were divided into sham group and I/R groups which would be tested se-ries time of 0.5 h, 1 2 4 d,7 d,14 d,28 d reperfusion to observe expression ZFP580 rat myocardium. The H9C2 cells cultured treated with transforming growth factor-beta1 (TGF-β 1) establish cardiac hypertrophy vitro model series 0 8h, 16 h 24 h....
During severe grid fault, doubly fed induction generator (DFIG)-based wind turbines (WTs) demand switching to transient controls (e.g., demagnetization control) suppress fault current. However, the stability considering LVRT control under weak has not been explored. To fill gap, this paper firstly established model of DFIG- based WT during taking into account. Based on it, DFIG-based is evaluated by Lyapunov's energy function and inverse trajectory method. It discovered that improper could...
