Tsawwassen VVO
The Tsawwassen VVO project was initiated to replace existing electromechanical protection (60kV to 12kV Transformer, Feeder, Bus) with Microprocessor based protection. The upgraded protection systems provide increased reliability, improved metering and control functionality. NextGen was also responsible for upgrading the Scada and Tap Changer control systems as well as AC and DC distribution systems.
The project included the supply of labour, tools and materials for the removal and replacement of existing equipment. The scope included the installation of new Protection and Control, SCADA, Automation, Metering and Telecom panels, cabinets and racks, as well as the removal and replacement of existing 120/208V AC Distribution Panels,125V DC Distribution Panel, 120/208V AC Transfer Cubicle, 30A Battery Charger and Eyewash station.
The work also included the wiring interconnection of all the new and existing equipment in the control room to existing equipment in the 60kV/25kV switchyard including the 125V DC Battery Bank adjacent to the control room.
Nextgen performed the testing and commissioning of all protective relays, control and automation equipment, RTU cabinet, and telecommunications equipment.
