Transient Stability : Defining Transient Limit Monitors<br />

The Transient Limit Monitors page is found on the Transient Stability Analysis dialog.<br />

When inserting a new transient limit monitor you are presented with the following dialog. This gives<br />

you great flexibility in defining monitors for the various values which can be recorded in a transient<br />

stability run. Note that there are some very simple Generic Limit Monitors for synchronous machines<br />

which are define as part of the Transient Stability options that may also be of use.<br />

In the top portion of the dialog you first give the transient limit monitor a name. There is then an<br />

option to make a transient limit monitor Active or not. Below the middle of the dialog there is the<br />

Action To Take options: Log Violation Only, Abort Simulation or Trip (Open) Device. The Log<br />

Violation Only will show the violation only in the message log. The Abort Simulation will abort<br />

simulation at a specified time after a violation of the monitor occurs. The Trip (Open) Device will<br />

option to trip/open a device" if a monitoring violation occurs (this works for Buses, AC Lines,<br />

Generators, Loads, and DC Lines). There is also a choice for Maximum number of violations of<br />

this limit monitor to store. This is needed so that too many limit violations of the same limit<br />
