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. substation assignment of buses and geographic coordinates of substations.proper identification and winding characteristics of auto-transformers and three-winding transformers, and.

generator step-up transformer parameters.Ī few less common parameters are also required:.transformer grounding configuration, and.GIC calculations use common power flow and fault analysis parameters, such as: The dc bias can force transformers to saturate for part of the normal ac cycle, causing harmonics, equipment damage, failure of protection schemes, reactive power loss, voltage instability, and potential large-scale voltage collapse.Įffect of GMD can be modeled as DC sources in transmission lines.īy integrating GIC calculations directly within PowerWorld Simulator, power engineers can readily see the impact of GIC on their systems and consider mitigation options. Induced currents flow through circuits formed by a high-voltage transmission line, a grounded transformer, the earth, and another grounded transformer at the far end of the transmission line. Power systems are vulnerable to time and spatial variations in dc voltages caused by GMD. A February 2012 NERC report contains several recommendations, including development of procedures and training for managing the effects of GMD events and enhancement of simulation tools and models to support the ongoing study of GMD impacts. If such a super storm strikes today’s power grids, outages and equipment damage could be unprecedented. A 1989 event caused widespread outages on the Hydro Quebec system, but this event was much smaller and less intense than a 1921 event that occurred prior to widespread electrification.
