| Abstract
|
The presentation will cover the following topics:
- Overview of 500 MW of recent wind turbine installations in Ontario with units rated 1.5 MW.
- Generators: 1200 rpm, wound rotor fed by variable speed drive, interconnection issues.
- Grounding challenges: sandy soil or rock, small footprints, no interconnected neutral, 2 - 10 kA fault level, uncertain current splits, conductive topsoil transfers in remote potential.
- Ground test issues: Clustered interconnected units form a large electrode, northern soil contains isolated pockets of low surface resistivity, fall of potential tests provide incorrect results for interconnected units and over two-layer soil.
- Description of new ground test method: proximity correction for C2 and P2 probes, averaging of multiple probe locations to reduce errors, standard deviation to provide an estimate of quality, measurement of current splits to verify models.

| Biography
|
Peter Dick retired in 2005 from Kinectrics Inc (formerly Ontario Hydro Research Division) after working there 30+ years. He earned a B.A.Sc. (Elec) from the University of Waterloo in 1971, a M.A. Sc. (Elec) from the University of British Columbia and holds the P. Eng. registration in Ontario. Peter's experience covers reviewing designs, testing, modelling, and coordinating stresses and withstands for most components of the electrical utility generation, transmission and distribution systems. In the year since retiring, he has continued offering engineering services on more than 30 projects operating as a sole proprietor under the business name Electric Power Diagnostics (EPD) and as an Engineering Associate to Kinectrics Inc. Many of these projects have reviewed the performance of station grounding systems. He is contributing to working groups related to IEEE Standard 80 on grounding design, IEEE Standard 81 on grounding tests and the Canadian Electrical Code, Part I Section 36
