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. Those described in TPL-007-2, Table 3: Geoelectric Field Scaling Factors, are available here (revised January 31, 2018). […]

Distributed Computing Setup

On both machines Ensure you have the latest Simulator build installed.  It should be the same version on both machines. Use the RegSimAuto utility in the Simulator installation directory to ensure the correct version of Simulator is registered. On the remote machine Set up a user that will be used to run distributed computation.  This […]

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 […]
