Earlier studies have demonstrated that phenol UDP-glucuronosyltransferase (UGT) activity is up-regulated by pregnant mare's serum gonadotropin (PMSG) in rat ovary, but not liver. This phenomenon was investigated in more detail in the present study. Ovaries and livers of immature rats, rats synchronized with respect to their preovulatory and corpus luteal phases by treatment with PMSG, and matur...

Synchronization and superovulation are commonly used to obtain large numbers of embryos for experimental and practical purposes. This study compared the number, quality, and in vitro development of embryos recovered from gilts following single or double estrus synchronization and superovulation. Prepubertal gilts from the single synchronization group were injected with 1500 I.U. PMSG and 1000 I...

This paper presents the dynamic model and Detail Analysis of a Wind energy conversion system equipped with permanent magnet synchronous generator (PMSG). There are different types of synchronous generators, but the PMSG is chosen, in order to obtain its dynamic model. It offers better performance due to higher efficiency and less maintenance since it does not have rotor current and can be used ...

The effect of superovulation by pregnant mare serum gonadotropin (PMSG) on autologous transplanted ovaries in the lumbar muscles of mice was histomorphometrically evaluated using the indices of number and volume of different kind of follicles and volume of corpora lutea, ovary, and stroma. Angiogenesis was observed after mouse ovarian transplantation on days 14 and 21 after ovarian grafting. Af...

This paper proposes a small wind energy conversion system comprises permanent magnet synchronous generator (PMSG), uncontrolled rectifier, conventional H-Bridge inverter and dc-dc bi-directional converter. The dc link capacitor is connected to a storage system through Bi-directional power flow link. A hybrid pulse width modulation (HPWM) controller is used to regulate the ac load voltage and fr...

A simple step and search control strategy for extracting maximum output power from grid connected Variable Speed Wind Energy Conversion System (VSWECS) is implemented in this work. This system consists of a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) through a gear box, a DC-DC boost converter and a hysteresis current controlled Voltage Source Converte...

Electrical energy concurrent which cannot be stored so must be utilized as soon as it is generated. Therefore it requires an effective balance of power flow within multi area power system. This paper studies about a two area system [Hydro power plant & PMSG based Wind energy conversion system] which is connected through a tie line. Due to the rapid fluctuation in the wind power it causes distur...

The control of a permanent magnet synchronous generator (PMSG) drive can be achieved through the implementation of different control techniques. This paper presents a comparative study of vector control and direct control techniques applied to PMSG drives for wind turbine applications. Rotor field oriented control (RFOC) and direct torque control (DTC) are considered for the generator-side conv...

This project deals with a grid connected wind-PV hybrid distributed generation system employing permanent magnet synchronous generator(PMSG) driven by a variable speed wind turbine and PV array connected to a load and the grid. PMSG wind turbine connected to a dc-dc converter via three phase diode rectifier and PV array along with a dc-dc converter connected to the DC link which operates under ...

In this paper, analyzing the operation of a Permanent Magnet Synchronous Generator (PMSG) based stand alone wind power system with Sensorless Maximum Power Point Tracking (MPPT) and a system for storing energy during wind speed and load variations. In standalone system, power, balance and power quality require the energy storage system. In conventional systems, MPPT depends on wind turbine para...
