The use of wind turbines is increasing at very high rates in many countries around the world. Studies to evaluate the impact of connecting these new generation units to the existing power systems must be done. This paper proposes a wind energy conversion system for a grid connected permanent magnet synchronous generator (PMSG) and power electronic converter system. The model includes a PMSG mod...

This paper proposes an optimized model and control strategy for variable speed wind turbine using permanent magnet synchronous generator (PMSG). Models and equations that describe different components of the wind energy conversion system (WECS) are addressed and their implementations into PSCAD/EMTDC are described. There are different types of synchronous generators, but the PMSG is chosen. It ...

This paper reports a case of super pregnancy in a BALB/c mouse pregnant with 30 pups following induction of superovulation using a PMSG-hCG protocol. Superovulation was induced in 10 mice by injecting 5 IU PMSG followed by 5 IU hCG 48 hours later. Immediately after injection of hCG, animals were placed with males at a ratio of 1 to 1 for 24 hours. On day 14 after mating, animals were killed by ...

Traditional permanent magnet synchronous generator (PMSG)-based wind turbine (WT) normally utilises phase lock loop (PLL) for obtaining accurate angle of AC grid to make sure maximum power point tracking (MPPT). However, a weak system with low short circuit ratio (SCR) and high control bandwidth PLL might have impaired effects on the stability system. To overcome these, novel PMSG-based WT form...

This paper provides an H∞ robust control strategy for a permanent magnet synchronous generator (PMSG)-based wind farm to realize subsynchronous resonance suppression (SSR) subject uncertain system distortions and parameter perturbation. Firstly, eighth-order state space mathematical model of PMSG-based is established, including the grid-side converter (GSC), GSC controller, phase-locked loop (P...

Abstract This paper is concerned with the modeling of three-phase permanent magnet synchronous generator (PMSG) and its load in dq0 reference system. The was considered to be directly connected a balanced load. loads under consideration were R RLC type loads. connection can simulated using standard PMSG dq model Park transformations, but requires system as whole. LabVIEW simulations these model...

A modified four-dimensional linear active disturbance rejection control (LADRC) strategy is proposed for a dual three-phase permanent magnet synchronous generator (DTP-PMSG) system to reduce cross-coupling between the d and q axis currents in d-q subspace harmonic x-y subspace. In subspace, uses model-based LADRC enhance decoupling effect axes ability against parameter variation. 5th 7th curren...

Abstract This paper provides a systematic analysis of the large scale PMSG (permanent magnet synchronous generator)-based WECS (wind energy conversion system) torsional vibration problem under MPPT (maximum power point tracking) control and constant control. is from perspective SSO (sub-synchronous oscillation), SSH harmonics) forced vibration. The cause negative total system damping, weakened ...

Wind is one of the most abundant renewable sources of energy in nature. Wind energy can be harnessed by a wind energy conversion system (WECS) composed of a wind turbine, an electric generator, a power electronic converter and the corresponding control system. The most advanced generator type is perhaps the permanent magnet synchronous generator (PMSG). As far as microgrid is concerned the load...
