Etap Analysis

Summary

  • Modeling & Simulation softwares hold great value for Power System Designers.
  • Engineers have to use these softwares all the time to analyze and test their designed before actual implementation.
  • Softwares are used for various analyses e.g, cost-benefit analyses, feasibility analysis, protection coordination etc before deploying the system.
  • Electrical Engineers use industry standard softwares to test their proposed designs.
  • For high performance computations and estimations, Matlab/Simulink is used.
  • For a basic introduction to Matlab for Power Engineers, you may want to have a tutorial on the topic of Matlab/Simulink for Electrical Power Engineers.
  • This tutorial series is based on ETAP usage fro Power System Modeling, Design and Analysis.
  • In this tutorial, we’ll be introducing basic user interface of ETAP, its functionality and different features that are useful in Power System modeling and analysis.
  • ETAP is a full spectrum analytical engineering software developed by Operation Technology Inc.
  • The software specializing in the analysis, simulation, monitoring, control, optimization, and automation of electrical power systems.
  • ETAP software offers the most comprehensive and integrated suite of power system enterprise solution that spans from modeling to operation.
  • The ETAP Software provides a good interface for performing rigorous analysis on electrical power systems and is one of the best in Electrical Transient analysis softwares.
  • It’s integration to Microsoft Excel is also one of its many amazing features.
  • The ETAP Software provides an easy to use, user friendly environment along with a comprehensive user manual that helps user through any problem encountered during simulation.
  • The Basic interface of ETAP is shown in figure below.
  • ETAP software is intelligently divided into different toolbars according to their functionality.
  • User can easily access each toolbar while creating one line diagram of a power system model.
  • Besides toolbars, there are different options available to perform analyses on the system model through study cases, configurations, edit toolbars.
  • Each one of them is described in this tutorial.
  • Mode toolbar is located on top of GUI jus tbelow the file menu.
  • Different Analysis Modes can be selected from this Mode Toolbar according to the requiremnt of the project.
  • In ETAP 16, a complete set of analyses has been provided through the mode toolbar as given in the list below:.
  • There are total 13 study modes in ETAP as depicted in Fig.
  • Each one of them is briefly described in the order from left to right:.
  • Load Flow: Used to perform load flow (or power flow) on power system modeled in one line diagram.
  • Unbalanced Load Flow.
  • ANSI Short Circuit Analysis.
  • Motor Starting Analysis. Harmonic Analysis.
  • Transient Analysis. Star Protection Coordination.
  • Optimal Load Flow. Reliability Analysis.
  • Optimal Capacitor Placement. DC Short Circuit Analysis.
  • Battery Sizing Analysis. When a specific analysis Mode is selected from Mode toolbar, various analysis options are available through the Analysis Toolbar.
  • Format for Analysis Toolbar under Load Flow Mode is show here.
  • As depicted clearly from above toolbar, once Load Flow Mode is selected; we can select any option from its Analysis Toolbar to run the load flow calculations, display results & alters, generate and export report and even collect live data from a real power system.
  • This tutorial provides basic introduction to ETAP, it’s features and capabilities.
  • In next tutorial, we’ll be building model of a small power system.
  • We shall build its one line diagram and then we’ll analyze the system for load flow.
  • Export output reports to your favorite word processor
  • Multiple plot database comparison in single window using Plot Analyzer™ tool
