Synchronous Machine Theory: New GENQEC Model
PowerWorld Director of Software Development gave a presentation at the WECC MVWG meeting in Salt Lake City on November 21, 2019. This presentations gives a very detailed theoretical look at where the synchronous machine numerical model comes from. Synchronous Machines Theory The presentation was given to provide background on where the need for a new […]

Applying Updates to Hardware Licenses
To perform the following instructions, you will need a .V2C file provided by PowerWorld. Once you have completed the following instructions, your hardware key will unlock Simulator or Retriever with the updated features. Locate the machine that hosts the hardware key. Simulator or Retriever must be installed on this machine to complete the process. Start […]

Distributed Computing Setup
Distributed Computation Configuration To quickly check the configuration of a given machine, use the Distributed Computation Configuration utility (DistCompCfg.exe in the installation directory of the Simulator version you would like to configure for Distributed use). If a step is not configured correctly, the checkbox will not be marked. All machines involved in a Distributed Computing […]

Using Contingency Categories for monitoring of different voltage deviation limits for different contingencies
Previous knowledge base articles have covered both Monitoring voltages for Post Contingency Voltage Drop Criteria Monitoring which covered how to monitor all buses in the system for a particular voltage drop. How to specify different Voltage Deviation Limits for different buses in Contingency Analysis which did a similar thing but allowed the criteria to be […]

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 […]

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 […]

Remote License Troubleshooting
If you are trying to start Simulator or Retriever using a remote license but the hardware key is not detected, you may need to manually point to the hardware key’s location on the network. To configure where your machine goes to look for remote license keys, make sure to run the full Simulator or Retriever installation […]

Video Capture
PowerWorld Simulator does not include a built-in tool for video capture or movie making. Commercial and freeware tools are available from other sources to capture video from PowerWorld Simulator, Retriever, and any other desktop applications. Current offerings may be found here, or by simply searching online for video capture software.

How do the key fields and required fields for aux files and copy/paste from Excel work?
Each object type in Simulator (i.e. Loads, Generators, Buses, etc…) has a number of key fields and additional required fields. Key fields are fields that must be included for existing records when pasting data into Simulator from a spreadsheet application such as MS Excel or when loading information from an aux file. Required fields are fields that must be specified (in addition […]

Can I solve a Real-Time power flow in Retriever?
Yes. The data that is imported from the real-time sources can be substituted for the underlying system data to solve a real-time power flow in Retriever, provided that: a complete system model with all required object fields necessary to run a power flow solution is provided (see case validation), and the underlying model fields (when […]
