Transient stability voltage collapse: See it with large plots and Min/Max result tracking
We had a rather strange support question from a customer running a transient stability run with a three-phase fault that was on for 2 seconds on a 230 kV bus (they were studying delayed clearing of a fault with about a dozen switching actions occurring which eventually cleared the fault after 2 seconds). The network boundary […]

Renewable Transient Stability Modeling for Wind and Solar plants
This article covers how to model a wind or solar plant using the second generation wind turbine models that have been developed through WECC’s Model Validation Working Group (MVWG). The details of these models are explained in detail in PDF documents on the WECC website at the following link: WECC MVWG Approved Model Specifications You […]

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 […]

Initial wiggles in a very small transient stability case
A common question when a user first starts playing with very small transient stability test cases is “Why do I see wiggles in my plots with no disturbance?” On large transient stability simulations there can be many different reasons for this, but for a 9 bus, 1 generator case you would rightly not expect to […]

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 http://www.wecc.biz/library/Library/Planning%20Committee%20Handbook/WECC-NERC%20Planning%20Standards.pdf). PowerWorld Simulator’s transient limit monitors allow you to monitor for violations […]
