The purpose of coating the inside surface of gas insulated busduct (GIB) enclosure with a dielectric material reduces the deleterious effect of electrode surface roughness, impedes the development of metallic particle initiated micro discharges, increases the field required to lift particles, and reduces the charge acquired by particles. The performance of particle contaminated compressed gas systems with dielectric coated electrodes are analyzed in this paper. The equations governing the motion of the particle due to its electromagnetic field effect has been formulated to obtain the particle trajectories. Hence simulation has been carried out to study the effect of fields on the motion of the particle with and without electromagnetic field effect under dielectric coated enclosure. Particle trajectories obtained for various voltages of aluminum, copper, and silver particles of size 12 mm in length and 0.2mm as radius present on the enclosure. The simulation results have been presented and analyzed.Keywords

The aim of the study presented in the paper is to propose a systematic simple method of Contingency Planning and Analysis. Contingency analysis is one of the basic power system studies. It refers to the security of the system operation under the loss of one or more of the major system components due to a random failure. The present day competitive market scenario demands zero tolerance for even single contingency. Therefore, there is great need to develop systematic plans which can be implemented to give fast and efficient results. The Novel Method proposed is tested on 9-Bus IEEE Test System and the results analyzed.Keywords
