Dr. Farrokh Shokooh is the founder of ETAP. While Dr. Shokooh worked at Fluor Corporation[4] he was made in charge of selecting electrical engineering software. Realizing a lack of comprehensive, efficient and intelligent power system analysis software, the vision of Electrical Transient Analyzer Program (ETAP) was born. Dr. Shokooh left Fluor Corporation to develop ETAP and founded Operation Technology, Inc (OTI) in 1986. OTI dba ETAP is an ISO 9001-certified electrical power system design and automation software company headquartered in Irvine, California, with international offices in India, UAE, KSA, Brazil, Mexico, France, UK, Malaysia and China.
Power system simulation requires an electrical digital twin consisting of a power system network model that includes system connectivity, topology, electrical device characteristics, historical system response and real-time operations data in order to make offline or online decisions. ETAP power engineering software utilizes an electrical digital twin in order for electrical engineers and operators to perform following studies in offline or online mode.[citation needed]
The ITER Project selected ETAP as the electrical analysis tool for several reasons. The U.S.nuclear qualification ensures high level of quality. Moreover, in an internationalenvironment like ITER, ETAP demonstrated a high level of support in all the countriesinvolved in the project.

SKM is probably the most widely used software package in the industry, providing a complete line of electrical engineering software that includes SKM Power Tools for Windows and Arc Flash Hazard Analysis. As with any software or tool, it is only as good as the operator and information put in. Our engineers have received extensive training and have the field experience to get the job done accurately and correctly. We also have years of experience the allow us to look at the results from the software and recognize when those results do not match expectations. SKM has proven, time and again, it is reliable with an extensive library, and a great customer support team for those times we need them.
ETAP is another widely used electrical system analysis software package that offers a host of integrated solutions including: arc flash, load flow, short circuit, transient stability, relay coordination, cable ampacity, optimal power flow and more. Both SKM and ETAP provide our team of highly skilled engineers the option of drawing the whole electrical system as a one-line diagram. Once the engineer inputs the information in for each component, the program conducts all the necessary calculations at once and makes necessary updates in calculations as changes are made. This helps to ensure the highest levels of quality control. Additionally, SKM and ETAP model files can be imported into AutoCAD, and both software systems allow for customizable labels though Microsoft Word.
These systems require advanced industrial electrical software tools for modeling and performing different studies, especially with the increasing availability of convertible equipment such as inverters, variable frequency drives and distributed energy resources such as photovoltaic and battery energy storage systems.
There are numerous industrial electrical system analysis software tools currently available for designers and engineers to analyze power systems, such ETAP, SKM PowerTools, EasyPower, PowerWorld, PSS E, PSCAD, CYME, DIgSILENT. These tools are capable of building complex electrical generation, distribution or transmission system models and performing a variety of system studies, such as load flow, motor starting and voltage stability, short circuit, protective device coordination and equipment protection, arc flash, harmonic, reliability, real time automation, control and monitoring.
Lighting design software, such as Elumtools, allows designers to perform photometric calculations in the building information modeling application because designers are typically already using BIM to develop models and engineering drawings. This integration allows the lighting designer to seamlessly use model parameters input into the BIM model to perform lighting calculations.
In general, several of these electrical and lighting software packages such as ETAP, SKM PowerTools, EasyPower or Elumtools can integrate into BIM workflows. Used in conjunction with data exchange modules, these software options can exchange data with BIM modeling software, such as Autodesk Revit to maintain the overall integrated design approach and consistency.
These bi-directional data exchange packages simplify and reduce cost of the electrical design process in short and long terms by using the data that already exist in the Revit to automatically generate electrical models to perform electrical system study (see Figures 1 and 3) or use it to design and analyze lighting calculations.
It is difficult to properly evaluate the right software and its limitations without making significant labor and financial investments. Regardless of the electrical software used, it is important for a facility to have such a model available and to regularly maintain it. Having a facility model can help to identify electrical system limitations and issues, improve system reliability and personnel safety and helps engineers with variety of system modifications such as microgrid to provide an alternative source for reliable and cost-saving operation.
The following example illustrates the need for an electrical software tool to model and perform a feasibility study for integrating a microgrid into the existing facility and evaluate different system configurations. Note that for this study, no Revit integration is used due to the small facility size. Revit integration is typically applicable to much larger and complex system where it can offer more benefits.
The DER is connected to utility system by a 500-kilowatt bi-directional inverter that can supply (from PV or BESS) or absorb (BESS charging) power. A simplified electrical system when the facility is fed from utility source is shown in Figure 4.
One of the advantages of having a facility electrical system model is to evaluate different system conditions and scenarios. Having a model will expedite time and accuracy to perform such modification and evaluate possible impact as far as system parameters such as power flow, available fault current, etc.
