Transient Stability Analysis: Results from RAM

Concept Link IconSee Also

 

The Results from RAM page is found on the Transient Stability Analysis dialog. This page provides a summary of various results from a transient stability analysis run. The results shown here are currently what is being stored in RAM.

 

 

The Results from RAM page is divided into several sub-tabs:

Time Values

This page contains a table of all results selected with Results to Store to RAM. For details on this display see Transient Stability Results: Time Values.

Minimum/Maximum Values

The Minimum/Maximum Values tab contains two lists: one of generators and one of buses. Each list contains summary information for the objects. The bus list contains information about the maximum and minimum voltage values and time. The generator list contains maximum and minimum information about angles and frequency. Note that when the Process Contingencies option is set to One Contingency at a Time, the list will only apply to the presently active contingency chosen from the For Contingency drop-down menu. (See Transient Stability: Running Multiple Contingencies.)

Summary

Time Solution Started

Time that the transient stability analysis started.

Time to Solve (Seconds)

Amount of computing time needed to solve the analysis.

Maximum Angle Difference (Deg)

Maximum angle difference between any two generator rotors at any time during the analysis.

Time of Max. Angle Diff. (Seconds)

Analysis time at which the maximum angle difference occurred.

Newton Solution Results

This contains information about the Newton Solutions needed during the Simulation

Events

The Events tab will show a list of events which occurred during the stability run.

The Events can be filter by Event Levels AND by Object Types. This facilitates the search of particular events easier to the user.

The user-defined transient contingency elements will be listed in the event list. In addition, any actions caused by the action of a relay or motor tripping action of one of the stability models may be listed as an event. An event will be shown id the network solution failed during the simulation.
