The Geographic Grid Ptolemy‚ a Roman mathematician‚ created the geographic grid. This grid is a system of invisible lines that span the globe. The grid has been used for over 2‚000 years as a reference for finding the location of a fixed position on Earth. There are certain components that make up the grid. Meridians run vertically and come together at the north and south poles. The center meridian‚ the Prime Meridian‚ divides the earth into eastern and western hemispheres. Parallels run horizontally

ABSTRACT This document provides information for a report to congress on Smart Grid security as required by Section 1309 of Title XIII of the Energy Independence and Security Act of 2007. The security of any future Smart Grid is dependent on successfully addressing the cyber security issues associated with the nation’s current power grid. Smart Grid will utilize numerous legacy systems and technologies that are currently installed.Therefore‚ known vulnerabilities in these legacy systems must

Grid Designing Abstract: In an increasing number of scientific disciplines‚ large data collections are emerging as important community resources. Grid computing has emerged as an important new field‚ distinguished from conventional distributed computing by its focus on large-scale resource sharing‚ innovative applications‚ and‚ in some cases‚ high performance orientation. The foundation of a grid solution design is typically built upon an existing infrastructure investment. However‚ a grid

EI2435 Faults and Transients on Transmission Lines Wang Wei weiwan@kth.se 1/12/2011 1. Introduction Project 1 is about fault currents and transients on transmission lines that may occur due a lightning strike to an overhead line. In this case the transmission line is energized from one side and it’s other side is terminated in a Gas Insulated Substation‚ see Fig. 1. Several issues will be investigated from this system such as transient overvoltages and short-circuit currents. Fig.1 Transmission
