Motor Load Starting using Transient Stability

Note: Download a small sample case at the following link which is used in this demonstrate: MotorStart Case Note: Starting in the July 10, 2013 patch of Simulator 17, a modification was made to automatically change the integration time step for the entire simulation when induction motors (loads) or induction machine (generators) drop below 0.1 per […]

How to specify when Transient Limit Monitoring starts monitoring for violations

Transient Limit Monitoring Many power systems require particular voltage or frequency performance during transient stability simulation.  For example, in the Western grid in the United States and Canada, the organization WECC specifies particular performance for various “Category B” or “Category C” contingency events (see PowerWorld Simulator’s transient limit monitors allow you to monitor for violations […]
