The major disturbance occurred in the Northern grid of India on 30th July of 2012 causes shutdown of power in eight state. The main cause was the mal functioning of distance relay due to power swing, weak inter-regional corridor and multiple outage of line. To avoid this situation a modified algorithm is proposed for numerical relay embedded with digital signal processor (TMS320F2812) to protect grid...
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...
Six-phase transmission line is an alternative solution for increasing the power transmission capability of overhead power transmission lines over existing rights of way. Double circuit three phase lines can be converted to six-phase transmission line. The idea of this new technique is very useful, but there are some protection problems due to complexity of the network. The modern Digital Signal Processor...
India has a very large electricity grid in the world, consist of five regional grids. The major disturbance occurred in the Northern grid at 02.33AM of 30th July 2012 leading to a blackout in nearly the entire northern region covering all the 8 States. The main cause was the mal operation of zone 3 distance relay due to load encroachment, weak inter-regional corridor and multiple outage of line. In...
