Pitch Angle Control for Variable Speed Wind Turbines

open access: yesRenewable Energy and Sustainable Development, 2015
.Pitch control is a practical technique for power regulation above the rated wind speed it is considered as the most efficient and popular power control method. As conventional pitch control usually use PI controller, the mathematical model of the system

Biphasic effect of PMSG on lactation in the rat [PDF]

open access: yesReproduction, 1984
Summary. A single injection of PMSG to rats on Day 10 of lactation produced a biphasic inhibitory effect on litter growth. The initial effect (24–72 h) occurred in conjunction with a rise in the concentration of oestradiol-17β and LH and a decline in serum prolactin, whereas the secondary effect (96 h onward) occurred in conjuction ...

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

open access: yesAdvanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

DFIG versus PMSG for marine current turbine applications [PDF]

open access: yes, 2012
Emerging technologies for marine current turbine are mainly relevant 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

Efeito do "PMSG" de diferentes origens na superovulação de camundongos

open access: yes, 1992
Female mice were superovulated with PMSG from different origins: local (PMSG-N), from France (PMSG-F) and from Canada (PMSG-C). Two response curves were studied using 5, 10, and 20 I.U.

Damping Torque Analysis of the PMSG-Based WT with Supplementary Damping Control for Mitigating Interarea Oscillations

open access: yesInternational Transactions on Electrical Energy Systems, 2022
This study presents a comprehensive analysis of the impact that a supplementary damping controller of the permanent magnet synchronous generator (PMSG)-based wind turbine (WT) has on low-frequency oscillation (LFO) damping.

Improving the Performance of PMSG Wind Turbines During Grid Fault Considering Different Strategies of Fault Current Limiters

open access: yesFrontiers in Energy Research, 2022
The wind energy conversion technology of a Permanent Magnet Synchronous Generator (PMSG) is very promising in renewable power generation. However, the performance of the grid-connected PMSGs is greatly affected by grid disturbances because their stator ...

Fosl2 Regulates FSH‐Dependent Follicle Maturation Through Feedback Amplification of FSH/FSHR Signaling

open access: yesAdvanced Science, EarlyView.
This study identifies a FOSL2‐driven positive feedback loop that amplifies FSH/FSHR signaling. During FSH‐dependent follicle maturation, FSH induces Fosl2 expression via the cAMP‐PKA‐CREB cascade. FOSL2 in turn binds the promoters of Fshr and estrogen‐biosynthesis genes to enhance their transcription, thereby increasing Fshr mRNA level and amplifying ...
