Step 1: Prepare load flow<\/div>\n
a) For the one-line diagram of Figure 1, convert all impedance, load, and voltage data to per unit using the system base data.<\/div>\n
b) Next, using the PowerWorld Simulator, create three input data files: busbar input data, line input data, and transformer input data.<\/div>\n
Note that bus 1 is the reference bus (swing bus). The purpose for this step of the study is to generate the three load flow input data files and correct the errors before proceeding to the next step. Requires system-by-unit knowledge.<\/div>\n
Step 2: Load Flow<\/div>\n
a) Run the load flow program and obtain the bus, line and transformer input\/output data files prepared in step 1.<\/div>\n
b) Suggest at least one method of increasing the voltage level at busbar 4 by 5%. Show the effectiveness of your method by making appropriate changes to the input data of case a) and running the load flow program. The purpose of this step of the work is to use voltage control methods, including the use of generator excitation control, changing and adjusting the tap of transformers, the use of compensation capacitors or other related devices (e.g. SVC (Static Var Compensator ) and STATCOM (Static Synchronous Compensator) and the addition of parallel transmission lines.<\/div>\n
c) Suggest ways to reduce the loading of the lines and especially the ones with the highest loading. Show the effectiveness of your method by making appropriate changes to the input data of case a) and running the load flow program.<\/div>\n","protected":false},"excerpt":{"rendered":"
