Location: Northeast

Segment: Hydroelectric

Problem: Obsolete control system

Solution: Hydro facility automation and protection upgrade

Results: PLC control system, protection design, governor and exciter systems.

Project overview

This hydro facility consists of two 9500kVA turbine generators operating at 4.16kV. The system also consists of multiple remote controlled gate houses. EatonT was awarded a turnkey contract as the Electrical & Control Equipment (ECE) contractor to design, supply and install the upgraded protection and control systems for the facility. Eaton’s complete overhaul of the controls systems enhances the ability of the utility to remotely monitor the condition and status of the generating plant. Resulting in faster response times to plant issues and greatly shortened start-up and shut-down times.
