• 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 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

• New! 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

• New! Performs steady-state stability profiling of load buses

• New! 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)

WeakLinks Professional

In today's market environment, load increases and generation outages in one area are met by raising the generation elsewhere. In order to be safe, MW rescheduling decisions, typically driven by price and availability, should also take into account the maximum transfer capability across the "links" that interconnect the areas involved in the transaction. This complex problem is solved by WeakLinks Professional^TM which

• Evaluates the stability of power transfers across interconnected systems

• Identifies, evaluates and ranks stability constrained transmission paths within the network

• Uses a solution technique that's field-proven, fast and robust

• Is suitable for off-line and real-time applications

• Provided as a stand-alone package or fully integrated with QuickStab^® Advanced

QuickStab^® Advanced and WeakLinks Professional^TM Fast, versatile and indispensable tools that can assist utilities to avoid the penalties, loss of revenues, and inconvenience caused by blackouts due to instability
