1 A Literature Survey on Different Power Mitigation Technology
Rakesh.R. Patil (M.Tech Power System),Prof. Alka Thakur (Associate Professor)

ABSTRACT - In this review paper discuss the different voltage flicker problem that is generate due to voltage up and down. This voltage problem generates flicker, and power quality degradation. The main reason of flicker generation is load change. Mainly caused by the amplitude change, not depended on absolute change. In the last decade there are different research work proposed on this flicker mitigation problem. In this survey paper discuss the different method to reduces this problem that is shown in this paper.
Keywords— Power quality, Voltage flicker, FACTS devices and MITIGATION

2 A Literature Survey on Speed Control of Asynchronous Motor using different Techniques
Piyush Rawat1, Prof. Jyotsna Sagar2

ABSTRACT —In this subject of Space vector control of motor requires an understanding of several topical areas, this report presents an understanding that was gained during this thesis work. The fundamentals of electric motors (particularly induction motors) are developed from first principles and the basic models are discussed. The theory of sinusoidal synchronous motors is reviewed. The concept of a complex space vector is introduced and developed using a working knowledge of the sinusoidal asynchronous motor. An overview of the operation of three-phase voltage source inverters is given, followed by an explanation of space vector modulation and its relationship to regular sinusoidal pulse width modulation. Torque control of the asynchronous machine is reviewed in several reference frames and then rotor-flux-field-oriented-control is explained. Finally, some schemes for space vector control operation are discussed.
