Surface electric field inputs to PowerWorld Simulator GIC are provided by Atmospheric and Environmental Research, a unit of Verisk Climate. Geo-spatially varying surface electric field simulated based on conditions of Mageomagnetic disturbance. It can also incorporate non-uniform and time-varying electric fields with direct input of transmission line DC voltage inputs or with third-party GMD event models. Peak surface electric field magnitude of the NERC Benchmark GMD Event: 8 V/km at 60 degrees north geomagnetic latitude and Canadian Shield earth resistivity. (See this knowledge base article for earth resistivity scaling models for the US and Canada.) PowerWorld Simulator can quickly auto-generate uniform electric field models, with the option to automatically scale the magnitude according to the parameters of the TPL-007-1 Benchmark GMD Event. NERC TPL-007-1 specifies study of a Benchmark GMD event, consisting of a geospatially uniform geomagnetic disturbance where the electric field magnitude varies with local earth resistivity and geomagnetic latitude. GMD-induced electric fields must also be provided, corresponding to a simulated GMD event or storm scenario. These may be industry data sets or auto-generated by Simulator. PowerWorld can provide geographic coordinates for the three primary North American planning models. These parameters can be estimated or defaults applied when actual values are not available.
PowerWorld Simulator GIC may be the most accessible tool in the world for power system planning and operations engineers to readily assess GMD risk posed to their systems.ĭownload the GIC Quick Start Guide, sample cases, and free demo version of Simulator. PowerWorld has developed an innovative tool for analyzing the potential impact of geomagnetic disturbances (GMD), using our familiar power flow and transient stability platform.
