Romero Engineering Co. engineers build custom detailed power system models of generation plants, transmission systems, distributions systems, renewable sources, such as solar and wind farms, and industrial facilities. These detailed models can then be used to simulate realistic power system behavior under different system conditions. The following is a summary of the software packages in which Romero Engineering Co. engineers build models:

• ASPEN OneLiner for short circuit analysis and protection coordination
• PSS CAPE for short circuit analysis and protection coordination
• EasyPower for short circuit analysis, protection coordination, power flow studies, dynamic stability studies, motor starting studies, and arc-flash hazard analysis
• ETAP for short circuit analysis, protection coordination, power flow studies, dynamic and transient stability studies, motor starting studies, and arc-flash hazard analysis
• PSCAD for electromagnetic transients analysis, including harmonics and power quality analysis, insulation coordination, temporary and switching overvoltage studies, and power system research
• RSCAD for electromagnetic transients analysis, hardware-in-the-loop testing of protection and control devices (e.g., protective relays, excitation controls, etc.), harmonics and power quality analysis, insulation coordination, temporary and switching overvoltage studies, and power system research
• SKM for short circuit analysis, protection coordination, power flow studies, dynamic and transient stability studies, motor starting studies, and arc-flash hazard analysis
