INTRODUCTION BDFRM is one of the new trends in partial variable speed wind turbine generators offering more advantages due to absences of brushes which improves it reliability making it more attractive specially for offshore wind applications. In addition to its “fail-safe” mode of operation which enables its robust operation in spite of the failure on its inverter or secondary stator. BDFRM has also reluctance rotor design which makes its rotor easier in manufacturing with less mechanical stresses in addition to absence of copper losses on rotor. On the other hands; the main drawbacks of BDFRM are the larger machine size due to its low torque to volume ratio, complex rotor design and complex controllability [1] BDFRM has two standard 3-phase windings on its stator. One connected directly to the grid and called the primary or power winding and the other is indirectly connected to the grid through back to back converter and is called the secondary or control winding. The rotor is salient pole reluctance rotor with no windings and its shaft is coupled to the wind turbine through a step-up gearbox. Fig.1 show the detailed construction of BDFRM. Number of poles of primary winding, secondary winding, and salient rotor must not be the same in order to produce useful torque. Also, primary winding is supplied by grid frequency while secondary winding is supplied by slip frequency. Construction and operation details will be handled in details through this paper. Due to existence of two frequencies, the most commonly modeling technique used for this machine is park’s d-q model using two arbitrary rotating reference frames and . The first one is for primary winding quantities and the other one is for secondary winding quantities. Where, is any arbitrary rotating speed, while is rotor speed [2-9]. This modeling technique is suitable for Fig.1.

However, in some cases the need for more detailed modeling techniques is required to model some special studies (e.g. study of winding inter-turn short circuit effects on machine performance).

The difficulties in the provision of such guarantees have limited the usefulness of MANETs. In the last decade, much research attention has focused on providing QoS assurances in MANET protocols. In this paper we have analysed different types of routing protocols and QoS metrics in MANETS. Secure AODV (SAODV) routing protocol modify the effect of AODV routing protocol. In SAODV is preferred to achieve best result in terms of end-to-end delay, energy packet delivery ratio and throughput.

In tall structures high lateral forces develop due to wind load and earthquake load are crucial. Thus the effects of lateral loads need consideration for strength and stability of the structures. The Outrigger in structures provides lateral stiffness that provides significant drift control for tall buildings. The study includes Rigid Frame, Shear Wall/Central Core, Wall-Frame Interaction, and Outrigger effect on tall structures. The objective of this paper is to study, the performance of outrigger structural system in high-rise building subjected to wind load and seismic load as per Indian standards. In the present comparative study, the static and dynamic behavior of the composite structure for different cases for 50 storey structure is modeled by using Finite Element Method. In this comparative study mainly the bare frame is compared with Steel outrigger with core for the structural efficiency is measured by the lateral displacement, storey drift, base shear and time period values. The Provision of outrigger along with shear wall core increases the strength as well as stiffness of the building against wind and earthquake loads and the shear walls without openings gives better results when compared to shear walls with openings and by providing the outriggers at different levels, the more reduction in lateral displacement and inter storey drift can be achieved.
