The Kingston Solar Farm saves approximatel y 14\,700 tonnes of carbon dioxide per year\, an amount equivalent to plan ting 3\,340 acres of trees and is the largest solar farm ever built in Can ada.\n\nThe Kingston Solar Farm which is owned by Kingston Solar LP has a generating capacity of 100 MW AC /140 MW DC and consists of six (6) distri buted zones interconnected by a 34.5kV distribution network. The solar far m is connected to the Hydro One 230 kV transmission system.\n\nThe most ad vanced grounding software CDEGS was used for the grounding system performa nce analysis to simulate a ground fault on the 230kV system to induce a GP R at the interconnecting substation and a transfer potential throughout th e solar farm.\n\nThis presentation will describe the limitations in terms of soil model variations and the maximum number of conductors / elements t hat were included in the simulation model. As a result\, special analysis methods had to be used for this large solar farm which included a simplifi ed overall model and further detailed analysis of the different zones usin g GPR energization.\n\nThis presentation will also describe the final desi gn of the grounding system including a combination of mitigation methods s uch as neutral grounding resistors\, crushed stone layers\, gradient contr ol conductors\, insulated fence sections as well as different interconnect ion methods between the zones.\n\nCo-sponsored by: CIMA+\n\nSpeaker(s): Pi erre Bérubé\, P.Eng.\, \n\nAgenda: \n5:30pm - 6:00pm: Networking and ref reshments\n\n6:00pm - 8:30pm: Presentation\n\nRoom: 8-207 \, Bldg: Donadeo Innovation Centre for Engineering (DICE)\, University of Alberta\, 9107 1 16 Street\, Edmonton\, Alberta\, Canada\, T6G 2V6 LOCATION:Room: 8-207 \, Bldg: Donadeo Innovation Centre for Engineering (DI CE)\, University of Alberta\, 9107 116 Street\, Edmonton\, Alberta\, Canad a\, T6G 2V6 ORGANIZER:Piero.Aquino-Meza@cima.ca SEQUENCE:4 SUMMARY:IEEE & ECE(Electrical and Computer Engineering @ University of Albe rta) Local Edmonton Event: "IEEE 80 Grounding System Analysis for Solar Fa rm in Kingston” URL;VALUE=URI:https://events.vtools.ieee.org/m/204072 X-ALT-DESC:Description: <br /><div dir="ltr">\n<p>This presentation will ha ve a brief introduction to the basics of substation grounding as per IEEE 80 and will describe the analytical methodology\, performance results and the grounding system analysis for the Kingston Solar Farm in Ontario.
