With a demanding deadline, the ambitious project by Belgian grid operator Elia went online in early 2019 without a glitch. Consequently, renewable energy generated by offshore wind is benefiting millions of homes and businesses in Belgium and beyond.

Belgium Integrates Offshore Wind Power Into European Grid 

In the early hours of the morning on a warm night in June, a group of engineers gathered in Georgia’s National Control Center. With quiet efficiency, they prepared to execute one of the most important tests the utility would ever perform, cutting the power to one of their most critical 500 kV transmission lines.

Innovation, Persistence, and a New Beginning

Traveling-wave fault locators are very accurate. To retain the inherently high per-unit fault location accuracy, utilities need a method to convert the per-unit fault location to the tower identifier in order to use their mapping data when dispatching line crews. This paper presents several methods for improving accuracy of tower position information for the purpose of dispatching line crews. These methods use past faults for which the location has been confirmed with high confidence, line taps, and Optical Time-Domain Reflectometry (OTDR) tests for identifying splice locations in the Optical Ground Wire (OPGW) cables.

Engineers and power system consultants who need a comprehensive understanding of the design concepts and methods used in protecting high-voltage power transmission should attend this class. PROT 407 provides an in-depth study of the methods used in designing protection for high-voltage power transmission lines.
