ELEN 3441 – Fundamentals of Power EngineeringLab # 16 Spring 2012 Lab 15: Introduction to ETAP. Objective: to become exposed to ETAP – a software complex designed to analyze power systems and their components. Equipment: PC with installed ETAP Introduction: According to its manufacturer, “ETAP offers a suite of fully integrated Electrical Engineering software solutions including arc flash, load flow, short circuit, transient stability, relay coordination, cable ampacity, optimal power flow, and more. Its modular functionality can be customized to fit the needs of any company, from small to large power systems.” “Operation Technology, Inc. is the designer and developer of ETAP, the most comprehensive analysis software for the design, simulation, operation, monitoring, control, optimization, and automation of power systems. ETAP is the industry leader used worldwide in all types and sizes of power systems, including generation, transmission, distribution, and industrial systems such as oil and gas, manufacturing, steel, cement, mining, data centers, nuclear facilities, transportation, smart grid solutions, renewable energy, and more.

Depending on the computer, this operation may take a few minutes. Be patient! Go to the “menu/open” command and select to open “Example ANSI”. Click “Ok” when prompted for user … and “Ok” for Project Editor. You should see a window similar to one in Figure 16-1: Page | 1 ELEN 3441 – Fundamentals of Power Engineering Lab # 16 Spring 2012 1 2 3 Figure 16-1 2) Switch to the Load Flow Analysis mode by clicking the button “1”. change the fuse value to what you think should be appropriate. Select “Alert View” (button “3”) and then “Critical…” to see critical errors. These errors rated as critical may lead to failure of the power system! Double-click “Fuse3” to display “SubNet 3” diagram and locate the Fuse3 (442 A). Check the warning generated. Run the Load Flow Analysis by clicking the button “2”. correct the “Sub3 Bus” error. If the value you selected for the Fuse3 is appropriate. Following the same approach. Click “Unit” to see the units. the warning for it should disappear. Go back to “Study View” and re-run the Load Flow test. You should see something like “Sub3 Bus is at 106%”. “Fuse3 is at 113. Page | 2 . click “Ok”.6%”. Double-click the fuse and go to Ratings. select the “Alert view” to inspect the errors generated. check the alerts and modify the circuit elements to clear them.ELEN 3441 – Fundamentals of Power Engineering Lab # 16 Spring 2012 3) Return to the “Study View” and switch to the Short Circuit Analysis mode. Page | 3 . Modify the appropriate circuit parameters to eliminate the critical errors. Run the “Arc-flash” test. After the test is over. In your report: No formal report is required. Please. do not save any changes to the example files when prompted. 4) Close ETAP. Run the “3phase device duty” test.
