The menu on the left side, those 9 callouts, are called pages. Therefore, the power grid page has 9 pages: Info, rating, short circuit, time domain, harmonic, reliability, energy price, remarks, and comments.

It is a shorter term for Generation Categories. You can see a list of names under Gen. Cat.: Design, normal, shutdown, emergency, etc. Those names are defaulted from the software and can be changed under settings.

We are your solution if you need any electrical engineering studies help, NERC, wind farms studies, training, public speaking, analysis of electrical incidents in the American grid, etc. Email, text, or contact us

The grid is an interconnected network designed for the delivery of electricity. In ETAP, the component that represents the grid is called the Power Grid. In SKM PTW, one of ETAP's competitors, the same component is called Utility.

The menu on the left side (callout 1) is called pages. Therefore, the power grid editor has 9 pages: Info, rating, short circuit, time domain, harmonic, reliability, energy price, remarks, and comments.

ID is a shorter term that stands for Identification. ID is a fancy 2 letter word ETAP chooses to use; it means nothing else than Name. You can type the name of your power grid editor. In my article, the ID is U2.

Let's run the model and see how the power grid works. In this model shown in Figure 4, you see the arrow away, pointing away from the power grid. 3514 kW and 1510 kVAR are being delivered to a facility.

They software is only forward compactible. Exchange of models between clients and designers wont be easy if we are using different versions.

I would to see the features such as lightning protection modelling using rolling sphere, EGM and shield angels. The software can only perform grid design for substation earthing only

Hello Percy, thank you for your positive feedback. We always add new and innovative features to our annual releases and take suggestions from our customers into consideration for future releases.

In regards to your question about lightning protection, you can utilize the ETAP emtCoSim module; and your feature request for "infinite busbar" you can utilize the bus editor and select "swing" to model an infinite bus.

1. The very attractive thing about ETAP is its user-friendly graphical interface which is very attractive with state of the art graphical symbols having both IEC and ANSI options selectable on simple clicks along with color coding according to voltage levels. This helps visually a lot in classifying one's systems based on voltage levels.

2. Help Desk support is an excellent feature with FTP support area for large file handling.

3. One click report generation with study/scenario wizards saves a lot of time for complex projects.

1. First is the dumpster. Once you delete an element, you can't simply undo to restore it from dumpster. You need to be super smart to get it back. The undo / redo should be smartly management as in many other software. It will save a lot of hassle and time.

2. Backward compatibility is also a major concern. Projects created in newer versions can't be opened in older versions at all which is required sometimes to review the work of contractors. It should have some backward compatibility, say, to 4 previous releases.

3. Static studies such as load flow, short circuit etc do not consider turbine rating to generate alerts as the same is needed in some plants where turbines are under-rated than associated generators. No documentation is also available in this regard.

4. Library updates are also not available until next version is released. Limited models are available for ASD/VFD drives for harmonic studies even for very common drives. One has to create every common model manually which takes a lot of time.

Thank you for your feedback. As you know, as a seasoned user, ETAP is thriving to deliver the best product on the market. As a user with a valid maintenance contract you may contact our 24/7 online HelpDesk or call ETAP support to assist you with these issues. In regards to backwards compatibility please contact one of our local ETAP offices or representatives for support with older releases.

Thank you for your recent review. ETAP is a very comprehensive software suite with hundreds of modules to choose from. We encourage all of our users to enroll in one of our many workshops around the world, with many available online now:

Grounding system study is inferior than other competitor such as XGSLab, CDEGS. Main Ground Grid analysis of ETAP is suitable only for a simple soil condition. I experienced very difficult soil condition with resistivity in the range of 800-1500 Ohm-m which ETAP cannot help and Electricity Authority disapproved analysis using ETAP. Thus we have to seek for other software to solve the problem by modeling a customized grid conductor such as using clay covering bare copper conductor and analyze touch and step voltage.

Cables sizing calculation still has no capability to calculate according to IEC60287 standard which calculate from heat transfer theory. I have to purchase other software, CYMCAP, to calculate correctly. So ETAP is used for power system analysis only except cables sizing calculation and grounding system study.

Another cons is ETAP support. I experienced that sometime I found problem using ETAP in analyzing GCB, I asked ETAP for technical help but unfortunately EATP ignored my request and after several follow up I got a very simple words which is not any useful. I felt very bad with ETAP support team. I hope that ETAP support would be improved.

Thank you for your feedback. We take our customer feedback very serious and will work on making improvements wherever we can. Please look for our next release which will have considerable enhancements for cables, including IEC 60287, ground grid analysis, and many more.

I would like to recommend trying our zones of protection viewer which sets the zones of protection and allows you to plot all the TCCs in one shot. The feature comes with protection device coordination.

This article demonstrates the high level step by step procedure to perform the protection and coordination analysis in ETAP software. Below are the steps: Select protective devices models from editor Once the single line diagram and data entry is complete

Inverter controls in AC microgrid allows delivering distributed power and providing grid support services during regular operation of the grid. It also allows the powering isolated islands in case of faults/contingencies to increase the performance and reliability of electrical system.

This article discusses about the importance of X/R ratio in low voltage short circuit studies. Introduction In some short circuit studies, the X/R ratio is ignored when comparing the short circuit rating of the equipment to the available fault current

Harmonic analysis methods help engineers to calculate system harmonic levels resulting from harmonic sources on the system. This also requires a knowledge of the harmonic source characteristics and a representation of the system frequency response characteristics. Below sections cover the

This article covers all about the introduction to impedance method for calculating voltage drop during motor start, sample hand calculation and its comparison with ETAP software. Introduction To Impedance Method Impedance method for calculating voltage drop during motor start involves

Fundamentally, the per-unit method (percentage method) is a calculating procedure. In this procedure, all equivalent system and circuit impedances are converted to a common kVA and kVbase. This permits the ready combination of circuit elements in a network where different

Introduction Power system switching transients occur each time, an abrupt circuit change occurs. This circuit change is usually the result of a normal switching operation, such as breaker opening or closing or simply turning a light switch on or off.

Selecting the right approach for starting large motors at the early stages of a project is very important. Hence, this selection will impact the integrity of the system, initial capital investment, operating costs and long-term reliability. This article helps in

This article covers the introduction of voltage drop causes and effect with calculation example of voltage drop. It is very important to understand the causes and effect of voltage drop which may occur due to certain parameters such as resistance/impedance,

This document contains parameters and calculations for a power grid system. The parameters include voltages, fault levels, impedances, ratings for a transformer, generator and motor. Calculations are shown to determine the short circuit MVA and fault current at different points in the system using the MVA method. A simulation in ETAP software is also run and results match the hand calculations, showing a fault current of 76 kA at Bus 4 which agrees with the calculated value of 75.63 kA.Read less

Ever the twain shall meet. The decentralization, democratization, and fragmentation of the power grid are yielding newer and more complex energy combinations these days, making room for these two very different energy assets to act together.
