In this work applications of Flexible AC Transmission System (FACTS) devices have been used in Automatic Generation Control (AGC) to improve the performance such as oscillation damping of transient response of power system in deregulated environment. The oscillations in frequency, tie power, generated power etc. are compared with conventional integral controller and FACTS devices. The responses improve further when Fuzzy controller is used in place of integral controller with FACTS devices connected to the system. © 2011 IEEE.

Using first principle calculation, we investigate the structural, electronic and magnetic properties of silicon doped zigzag boron nitride nanoribbon (ZBNNR). Our results show that the shift in position of silicon doping with respect to the ribbon edge causes change in the structural geometry, electronic structure and magnetization of ZBNNR. The band gap of silicon doped ZBNNR is found to become narrower as compared to that of perfect ZBNNR. We find that band gap and magnetic moment of ZBNNR can be tuned by substitutional silicon doping position and doping concentration. © 2015, EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

A major grid disturbance occurred in the Northern grid of Indian power grid on 30th July 2012, causing a blackout in northern region. The main cause was the malfunctioning of distance relay due to power swing, weak interregional corridor and multiple outage of lines. In this paper a power swing is compensated by thyristor controlled series capacitor (TCSC) to prevent the unnecessary tripping of line due to power swing and avoid cascading tripping and unforeseen blackout. The power swing is compensated by installation of TCSC at optimum location and controlling the impedance of line by changing its reactance; the oscillation is also damped out by TCSC. The distance relay used for power swing protection does not issue the trip command due to power swing compensation. The TSCS model is simulated for power swing compensation and gives the expected results and prevents the blackout in electricity grid. This paper describes the compensation technique for mho relay to protect the transmission line under power swing. © 2015 IEEE.

This paper presents the design of a 16bit Sigma Delta Digital to Analog converter for audio applications. Sampling rate conversion plays a predominant role in the signal processing and has a strong determination on the overall complexity and cost of efficient digital to analog Sigma Delta converter. In this paper a technique to examine filter architectures that can be effectively applied in the design of interpolator is presented. In addition a cascade multi bit design of sigma delta Modulator digital to analog architecture is also presented. Then a comparison is shown on multi bit single loop and cascade design based upon SNR, NTF and stable amplitude for audio applications. © 2015 IEEE.
