This ETAP Tutorial aims to introduce the Load Flow Analysis module. It also provides step by step instructions on how to run a load flow study, which is considered as the bread and butter of a power system engineer. An example of how to regulate bus voltage using transformer LTCs and how ETAP marks overload conditions will be given. Moreover, the Load Flow Result Analyzer will be quickly presented.

The ETAP Load Flow Analysis module helps power system engineers to simulate the bus voltages, branch power factors, currents, and power flows throughout the electrical system. It allows for swing, voltage regulated, and unregulated power sources with multiple power grids and generator connections. It is capable of performing analysis on both radial and loop systems. Moreover, ETAP Load Flow permits the user to choose from three different methods (Gauss-Seidel, Newton-Raphson and Fast Decoupled) in order to achieve the best calculation efficiency. Subsequently, the module aids the power system engineer by fast tracking the long computations and providing valuable time for the more important analysis and decision-making.

At the end of the tutorials, one should be able to familiarize the steps in running a complete Load Flow study using ETAP. This learning will be handy in evaluating steady-state voltage variations due to changes in load, incoming voltage and connection of other electrical equipment to the electrical system. Other benefits include system loss calculation and system capacity planning.
