Electrical Transient Analyzer Program

Electrical Transient Analyzer Program (ETAP) is an electrical network modeling and simulation software tool[1] used by power systems engineers to create an "electrical digital twin" and analyze electrical power system dynamics,[2] transients and protection.[3]

Dr. Farrokh Shokooh is the founder and current CEO 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.

ETAP was developed for utilization on MS-DOS operating system and intended for commercial and nuclear power system analysis [5] and system operations. OTI has been developing ETAP for 30 years by providing the comprehensive and widely used enterprise solutions for generation, transmission, distribution, industrial, transportation, and low-voltage power systems.

OTI has generated numerous innovations and patents throughout the years, including the first digital twin driven predictive simulation and automation platform; the first Intel-based energy management system based on the MS-DOS platform in the 1990s; the first comprehensive advanced user interface and situational awareness system for transmission, distribution, and generation operators; the first advanced intelligent load shedding system in the mid-2000s; and the adoption of big data technology and no-SQL database technologies.[citation needed]

Today, OTI provides electrical design to operation on a single platform, open automation, network management, and optimization solutions worldwide. The company offers supervisory control and data acquisition (SCADA) systems, energy management systems (EMS), generation management systems (GMS), advanced distribution management systems (DMS), substation automation systems (SAS), data warehousing (historian) analytics, distributed energy resource management systems (DERMS), situational intelligence systems, and individual software and hardware products for electrical system operations.

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:

  • Load flow or power flow study[6]
  • Short circuit or fault analysis[7]
  • Protective device coordination, discrimination or selectivity[8]
  • Transient or dynamic stability.[9]
  • Substation design and analysis[10]
  • Harmonic or power quality analysis[11]
  • Reliability[12]
  • Optimal power flow
  • Power system stabilizer tuning[13]
  • Optimal capacitor placement[14]
  • Motor starting and acceleration analysis[15]
  • Voltage stability analysis[16]
  • Arc flash hazard assessment[17]
  • Ground loop impedance calculation[18]
  • Battery modeling and simulation[19]

Software applications

ETAP software applications include:

  • Power system design for ANSI and IEC networks[20]
  • Electric supply substation simulation[21]
  • Monitoring and feeder analysis[22]
  • Simulation of distributed photovoltaic power[23]
  • Study of a DC network[24]
  • Open-phase fault analysis[25] - Multiple events across the nuclear power industry have highlighted the need for greater understanding of what happens during an open phase fault. These open phase events have occurred on the high side of offsite power supply transformers and have involved loss of one or two phases.
  • Diesel power plant analysis[26]
  • Combined cycle power plant analysis[27]
  • AC/DC hybrid system simulation[28]
  • Wind turbine design and analysis[29]
  • Harmonics in railway power systems[30]
  • Rural distribution system analysis[31]
  • Distributed generation protection[32]
  • Reliability assessment of renewable energy systems[33]
  • Wind and PV penetration studies[34]
