In an industrial environment more number of motor load are operated through power
electronic control device. As a characteristic of power electronic controller,the non linear in
the load will detoriated power quality in the system which may lead to increase in power
losses. With the development of power electronic controller using multilevel switching
device it is possible to improve the power quality.
This paper present analysis of improvement in the power supply and power quality
compensation feeding to a nonlinear load in industrial environment. Exhaustive simulation
research is presented to verify the performance analysis.
In last decade, research has been carried out to address the problems associated with power quality improvement issues. The power quality is affected mainly due to the sensitive loads which results in voltage sag and voltage swells. It is necessary to investigate the suitable methods for mitigation of voltage sags. From the wide range of mitigation methods, the selected one has to be observed for the effect on the characteristics. Authors have carried out the study and implementation of mitigation method to address the stated problem. In this paper, authors have implemented Dynamic Voltage Restorer (DVR) based on application of Space Vector Pulse Width Modulation (SVPWM). The implemented model gives remarkable results and mitigation of voltage sag is achieved.
In today’s world it has become a very important that electrical power must be made available to the customer 24 x 7. This fact attracted researchers and it increased focus on large scale integration of new renewable energy sources like wind power and solar power introduces the need for energy storage. Superconducting Magnetic Energy Storage (SMES) is a recent and promising alternative for active power compensation. Having high efficiency, very high response time and high power capability it is ideal for smoothing fast fluctuations. Superconducting Magnetic Energy Storage is a promising technology that stores electricity from the grid within the magnetic field of a coil comprised of superconducting wires with near zero loss of energy.
