Bishops Falls Hydro Station Governor / Automation Programming
Programmed eight AB SLC 500 PLCs & PanelView 550 OITs to control seven hydro-electric governors and related equipment.  System automated all turbine/generator control and alarms functions, governor speed and load regulation, auto start/stopped units, interfaced with existing SCADA RTU, and communicated with a high-level water level control system via an Ethernet Network.  Project included coordination of seven PLCs (one per unit) and a shared automatic synchronizing system.

A particular challenge on this project was the remote location and schedule for project commissioning.  This plant is located on the Exploits River in Bishop's Falls, Newfoundland.  Due to scheduling restrictions commissioning and installation was performed during the winter of 2002-2003 under extreme weather conditions.  Commissioning of the control and hydraulic systems as well as electrical control installation was supported by Casco Systems end to end, culminating in the commissioning of six new American Hydro Seagull horizontal 3MW turbine/generator units and the reconditioning of a seventh existing unit.  When completed the plant was able to be run remotely from the clients SCADA control center, providing a reliable, cost-effective power plant.
