GIC Time Varying Electric Field Example

PowerWorld Simulator supports binary and text file formats for time and spatially-varying geomagnetic disturbance (GMD) surface electric field inputs. This format allows development of detailed solar storm scenarios based on historic events or 3D earth conductivity models. Sample (B3D binary format) based on June 22, 2015 event [1], over footprint of the U.S. State of […]

New Feature: Data Check

A new feature was added to PowerWorld Simulator in the April 9, 2018 patch of Simulator 20 called “Data Checks”. Data checks grew out of work that PowerWorld customers Jonathan Young (Columbia Grid) and John Gross (Avista Utilities) performed building on PowerWorld Simulator’s features of Advanced Filters, Calculated Fields, Dynamic Formatting, Expression and String Expressions. […]

Earth Resistivity Model for GIC Calculations

PowerWorld Simulator GIC can automatically incorporate scaling factors for geomagnetic latitude and earth resistivity according to NERC TPL-007-2 – Transmission System Planned Performance for Geomagnetic Disturbance Events (October 2017). The earth resistivity models must be loaded from an auxiliary file. The following models are available: as described in TPL-007-2, Table 3: Geoelectric Field Scaling Factors as […]

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 […]

Play-in time series measurement data with PlayInGen model for Power Plant Model Validation (PPMV)

PlayIn models can be found in the Transient Stability add-on of Simulator. Many dynamic models comprise of differential-algebraic equations that respond to perturbations in a simulation. In contrast, these PlayIn models are used to input time-series data into a transient run at specified time points. In Simulator, a PlayIn Configuration object can be used to store […]

Adding Voltage Compensation to a Generator Model

Generator Voltage Compensation The input signal to Exciter models is a voltage signal (often labeled as either Vc or Ec on a block diagram).  In the simplest form this is just the per unit voltage magnitude of the terminal bus of the generator.  However, sometimes instead of using that voltage signal directly, the voltage is compensated by attempting to control […]

Complete Case Auxiliary File Export Format Descriptions

PowerWorld’s Auxiliary File Format is very flexible in providing a mechanism for saving model information from PowerWorld Simulator.  It also provides a great way to share information with others.  This flexibility however has some downsides as puts additional burden on the user to know which things to save.  Many tools within PowerWorld Simulator overcome this by including […]
