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...

A new maximum power extraction (MPE) controller for variable speed permanent magnet synchronous generator (PMSG) wind energy conversion systems (WECS) is proposed. The proposed controller generates optimum speed reference signal for the speed control loop of the vector controlled machine side converter control system without requiring the knowledge of wind speed using only active power and air ...

An attempt is made to induce the pethidine suppressed gonadal activities by the administration of exogenous gonadotropins (hCG, PMSG, hCG + PMSG). Administration of 5 IU gonadotropins either separately or in combination to the rats treated with pethidine for 30 days resulted in the significant increase in the weight of testis, diameter of testis and seminiferous tubules. Gonadotropin(s) treatme...

Variations of marine current speed can lead to strong fluctuations in the power extracted by a marine current turbine (MCT). During short-time period, swell effect is the main cause for the current speed variations. Conventional tip speed ratio Maximum Power Point Tracking (MPPT) algorithm will require the MCT to accelerate or to decelerate frequently under swell effect, which can cause severe ...

The common palm civets (Paradoxurus hermaphroditus) belong to the family (Viverridae), carnivores order (Carnivora). This animal is widely distributed in South and Southeast Asia. Currently, are raised quite popular Vietnam. delay breeding for first time slow rut has reduced economic efficiency civet farming. study was carried out evaluate effectiveness of different doses hormones (PMSG, HCG) o...

Permanent magnet synchronous generators (PMSG) have a huge potential for direct-drive wind power applications. Therefore, optimal design of these generators is necessary to maximize their efficiency and to reduce their manufacturing cost and total volume. In this paper, an optimal design of a six-phase 3.5 KW direct-drive PMSG to generate electricity for domestic needs is performed. The aim of ...
