The document provides instructions for a laboratory experiment to calculate line outage distribution factors (LODFs) for transmission line outages using Power World Simulator software. It includes background theory on LODFs and linear sensitivity factors for contingency analysis. The experiment involves calculating LODFs for outages of lines 1-2 and 2-3 using Power World Simulator and provided system data for a 6 bus system, and presenting the simulation results and conclusions.

Theory: To studying thousands of possible outages becomes very difficult to solve if it is desired
to present the result quickly. One of the easiest ways to provide a quick calculation of possible
overload is to linear sensitivity factor

Example: For a given system data calculate the line outage sensitivity factor for outages of lines
1-2 and 2-3 The following is the data for a six bus System

Bus Voltage Generation Load Bus
