PROJECT DESCRIPTION

Black & McDonald (B&M) was awarded a contract for the detailed engineering, procurement of materials, and construction of two protection, control and telecom buildings.

Two 14 ft. x 47 ft. buildings house the protection and control equipment for the wind farm including protective relay devices, telecommunication equipment, breaker/disconnect switch controls, and network architecture equipment.

B&M SCOPE OF WORK

The project involves conceptual design, detailed engineering deliverables, specification and procurement of equipment from various suppliers, shop assembly, building integration and factory testing. This includes:

• Creation of Connection Wiring Diagrams (CWDs)
• Updating and verification of Elementary Wiring Diagrams (EWDs)
• Protective Setting Implementation for line/transformer differential, distance, restricted earth fault, breaker failure, current, voltage, and frequency elements
• Creation of logic diagrams
• Procurement of major equipment, relays, FlexiTest switches, network switches, control/selector switches, lockout relays
• Testing and commissioning
• Factory acceptance testing, quality checks
• Supply of 14 ft. x 47 ft. building for the substation with eight P&C racks
• Supply of 14 ft. x 47 ft. building for the switching station with six P&C racks
• Installation of step-up transformers and connections of the transformers to the substations and interconnection of the entire system to the IESO controlled grid

The project was designed to consist of 110 Vestas V82 wind turbines. A 44 kV connection system that included both underground cable and overhead power lines was installed to connect to the turbines. Additionally, a 44/230 kV substation was built to step-up the generation to 230 kV for connection to the Hydro One owned 230 kV circuits.
