ROLE OF DYNAMIC VOLTAGE RESTORER IN POWER QUALITY – A REVIEW [pp 01-05]

Balwant Barkhaniya, Madhu Upadhyay

Abstract – Dynamic Voltage Restorer (DVR) is a modern and key custom power device to maintain the power quality. The DVR is a series compensator implemented to mitigate voltage sags and swell and to restore load voltage to its rated value. The Dynamic Voltage Restorer (DVR) is of high dynamic response, flexible and efficient solution to voltage sag and swell problem finally power quality problems using a robust in-phase…

DESIGN & SIMULATION OF DYNAMIC VOLTAGE RESTORER FOR POWER QUALITY IMPROVEMENT [pp 10-15]

Balwant Barkhaniya, Madhu Upadhyay

Abstract – Power quality issues is a key issue in recent time where mainly the disturbances like voltage sag, voltage swell and faults are the mail causes. In this paper Dynamic Voltage Restorer (DVR) is implemented to mitigate the vulgate sag, swell and faulty disturbances. A dynamic voltage restorer (DVR) is a custom power tool used to correct the voltage sag by voltage as well as power injection. The DVR is a series type of compensating device implemented to….

STUDY OF PERFORMANCE OF CEILING SWIRL DIFFUSER PLACEMENT IN INDOOR ENVIRONMENT [pp 20-24]

Paresh Korde, Dr. Shailendra Dwivedi

Abstract – An air diffuser while placing in an indoor office space has been the most important consideration for human thermal comfort. To obtain a maximum thermal comfort in an open indoor space the velocity of air and swirl produced by diffuser also has a huge impact. In this thesis we have worked to obtain a better temperature distributed in an indoor space as well as to get a better effect of swirl. We have observed the performance of ….

TWO DIMENSIONAL AEROFOIL WIND TURBINE BLADE DESIGN AND ANALYSIS USING CFD ANALYSIS [pp 25-27]

Kamal Bhan Singh, Yogesh Mishra

Abstract- In the current scenario, wind turbine energy accounts for 70% of total renewable energy used in India. The Indian wind energy sector has a capacity of 20 GW installed (as on 31.5.2017). In terms of installed wind power capacity, India ranks fifth in the world and is regarded as a major player in the global wind energy market. For the current work, a design method based on modelling in Uni-graphics and followed by simulation using the CFD (Computational Fluid…
