PowerWorld Software and Services

• Simulator ATC (Available Transfer Capability): calculates capacity of transmission network to support power transfers, subject to transmission line and interface limits; may be used with or without contingencies.
• Simulator PVQV (Voltage Stability Tools): calculates capacity of transmission network to support power transfers, subject to static voltage stability margins (PV curve); Also determines reactive power load margins at specified locations (QV); May be used with or without contingencies.
• Simulator Transient Stability: simulates the system's transient response to faults; the tool includes the ability to batch process multiple faults and a powerful plotting utility.
• TransLineCalc Transmission Line Parameter Calculator: computes lumped impedance parameters based on line length, conductor type, and tower configuration.
• One-line Diagrams (Transmission Atlas): graphical power system representation for visualization and interaction with PowerWorld products
