The Energy Sector, Power Distribution Division of Siemens Aktiengesellschaft (Siemens) together with SCS Info Tech, LLC (SCS), a New York based company announced the acquisition by Siemens of QuickStab^®. Siemens took over the enhancement, further development and continuing support of QuickStab, and is now distributing it worldwide both in real-time, on its flagship Spectrum Power SCADA/EMS solutions, and as a stand-alone offline application (read more...)

Here are just a few notable facts about this industry-unique application:

• Seamlessly integrated with the real-time and study-mode network analysis sequence by the major SCADA/EMS vendors (read more... check the latest press releases about new QuickStab^® users and upgrades of existing installations )

• The field-proven Real-Time QuickStab^® Extensions provide for easy, “do-it-yourself” integration of the computational and display engines of QuickStab^® with new or existing SCADA/EMS systems (read more...)

• Used by Electric Utilities (read more...), Independent System Operators (read more...), Transmission and Market System Operators (read more...), and National Dispatch Centers (read more...) in system dispatching and market operations -- read more about real-time implementations

• Performs fast voltage stability analysis and dynamic contingency assessment both for the current state estimate and for postulated scenarios (read more...)

• Computes the critical system MW loading where voltages may collapse and units may lose synchronism

• Identifies the safe operating margin in which there is no risk of instability

• Evaluates and ranks the generators’ impact on the overall system stability conditions -- in the base case and for single and multiple generation and transmission contingencies

• Supports look-ahead voltage stability studies where the load can be increased/decreased on user-selected buses or system areas whereas the generation is rescheduled in accordance with user-specified patterns

• Performs steady-state stability profiling of load buses

• Ranks the generators in the order of their impact upon user-selected load buses

• Helps monitor the distance to instability on real-time SCADA trending charts (download actual trending chart taken from a real-time system) -- “The era of real-time tracking of the risk of blackout has begun ...(read more...)"

• Displays the risk of blackout in a graphical format that’s easy to understand

• Compares base case results with those from contingency scenarios on innovative speedometer charts -- (read more...)

• It's fast -- 3382 bus system is evaluated in 1 second on PC; the complete solution of a dynamic contingency case or the solution of a look-ahead voltage stability study is calculated within approximately1.5 seconds

• It’s accurate - published results of independently conducted benchmarking studies confirm its precision and reliability, e.g., as reported in Chapter 3 and Appendix A in Real-Time Stability Assessment in Modern Power System Control Centers, Wiley-IEEE Press, New York, 2009, ISBN 9780470233306 http://www.wiley.com/ieee (click to review additional accuracy testing results)
