If a plasma cloud crosses the earth’s path it interacts with t he earth’s magnetic field to produce geomagnetic disturbances (GMD). Dur ing geomagnetic disturbances variations in geomagnetic (at frequencies in the order of 1‑100 mHz) induce voltages in relatively long transmission lines at ground level\, which in turn can result in quasi-dc induced curre nts (GIC) that can see their way into power transformers causing asymmetri c saturation. The ac power system is not designed to handle dc currents ov er long periods of time (from hours to days). A GMD event caused an 8 hour \, wide area blackout in Quebec in March 1989. This presentation will prov ide an overview of the physics of this phenomenon from an engineering pers pective and the impact on the power system.\n\nNERC reliability standards on Geomagnetic disturbances\n\nNERC (North American Reliability Corporatio n) has issued two reliability standards to address the impact of geomagnet ic disturbances (GMD) on the power system (230 kV and above). The first st andard EOP-010 addresses operational measures and the second one TPL-007 a ddresses planning mitigation measures. Both standards are already in place and utilities and system operators in Canada are getting ready to achieve compliance. A Canadian variance on TPL-007 is in the process of being app roved by NERC. This presentation will provide an overview of these standar ds and their impact on system operators and asset owners (such as the IESO \, Hydro One and OPG in Ontario)\, both in terms of required system studie s and the potential cost of mitigation measures to achieve compliance.\n\n Speaker(s): Dr. Luis Marti\, \n\nRoom: SHE549\, Bldg: Sally Horsfall Eaton Centre\, 99 Gerrard St E\, Toronto\, Ontario\, Canada\, M5B 2M2 LOCATION:Room: SHE549\, Bldg: Sally Horsfall Eaton Centre\, 99 Gerrard St E \, Toronto\, Ontario\, Canada\, M5B 2M2 ORGANIZER:ksubramaniam@ryerson.ca SEQUENCE:25 SUMMARY:Space Weather and Compliance with NERC Standard TPL-007 and EOP-010 Seminar URL;VALUE=URI:https://events.vtools.ieee.org/m/189260 X-ALT-DESC:Description: <br /><p><strong>Effects of Space Weather on Power Systems</strong></p>\n<p>Solar disturbances can release clouds of high ene rgy plasma into space during coronal mass ejections.&nbsp\; If a plasma cl oud crosses the earth&rsquo\;s path it interacts with the earth&rsquo\;s m agnetic field to produce geomagnetic disturbances (GMD). &nbsp\;During geo magnetic disturbances variations in geomagnetic (at frequencies in the ord er of 1‑100 mHz) induce voltages in relatively long transmission lines a t ground level\, which in turn can result in quasi-dc induced currents (GI C) that can see their way into power transformers causing asymmetric satur ation.
