select a length value within these limits), L3 = 40 km, L4 = 15 km,

a) For the monogram diagram of Figure 1, convert all impedance,
load and voltage data to
units using the system base data and Next, using PowerWorld
Simulator, create three input data files: balance input data, line
input data, and transformer input data.Also Run the load flow
program and obtain the input / output data files of scales, lines,
and transformers that you prepared. After propose at least one
method of increasing the voltage level on the balance 4 by 5%.
Demonstrate the effectiveness of your method by making appropriate
changes to the input data in case a) and executing the load flow
schedule. The purpose of this step is to use voltage control
methods, including the use of generator excitation control, change
and adjustment of transformer reception, use of compensation
capacitors or other related devices (eg Static Var Compensator
SVC). ) and STATCOM (Static Synchronous Compensator) and the
addition of parallel transmission lines. At the end suggest ways to
reduce the load of the lines and especially those with the highest
load. Demonstrate the effectiveness of your method by making
appropriate changes to the input data in first case and
executing the load flow schedule
