Load Flow Analysis of 220 kV Lines

The objective of this project is to present the idea of power flow analysis in a power system. Power flow or load flow studies constitute an important part of analysis and design of any power system network. This analysis can be carried out during the state of planning, operation, control and economic scheduling. The significance of power flow or load flow studies can be most useful during the planning of future expansion of a power system as well as in determining the best operation of the existing systems. From the results of simulation, the contingency conditions like overloading will be identified and suitable measures can be suggested for a better operation. Improvements such as up gradation of substation, tap changing of transformer, static capacitor banks for reactive power compensation, replacing single circuit lines by double circuit lines might be found effective in improving the voltage.
