Newport Hydro Automation
Developed PLC program and HMI system for three unit hydroelectric station.  This system provided automatic generator start and stop capabilities, alarm monitoring and annunciation, data logging and trending, and various control modes including load level control, pond level control, and gate position control.  System also provided remote control of head gate and minimum flow gate via a fiber optic Ethernet LAN.  In addition the control system provides dial in capabilities for remote monitoring of station condition by plant personnel.

Lamoille River Control System
HMI / SCADA system to provide supervisory control of four hydroelectric plants utilizing open architecture TCP/IP WAN and CIMPLICITY HMI software.

Clark Falls, Milton, & Peterson Hydro Station Automation
Replace ACS RTU's with S90-30 PLC SCADA system solution.  Expand system to provide load, pond, and gate position control, auto start / stop, and alarm annunciation.  Interface with Rubber Dam control system to coordinate water level control using dam, boards, generators, and minimum flow gate.
 

Weldon Hydro Station Automation
Developed PLC program to retrieve data from 14 GE Multlin 489, 745, & 750 relays, 4 Cutler-Hammer Exciter Control Units, and 4 Nexus 1250 Power Meters.  This program retrieved all metering data necessary for display on the Station SCADA system.

Gardiner Hydro Station Automation

Completed automation upgrade of a semi-Kaplan generator and related auxiliary equipment.  Project included removing an existing GE Fanuc Series 6 PLC and OIT system.  These were replaced with a VersaMax PLC and CIMPLICITY HMI SCADA program.  System is capable of automatic start and stop, pond level control, and remote lockout reset to allow roving personnel complete flexibility in operating the plant.  SCADA access was provided using a dedicated Web Server, allowing remote workers to connect to the site using only a Java enabled web browser.

Hydro Station Fish Elevator

Programmed and commissioned GE Fanuc 90-30 PLC logic and Wonderware InTouch SCADA/HMI system to automate a fish elevator and associated water control system.  This fully automated system controlled 3 modulating valves to provide attraction water through a fish passageway at specific flow rates and velocities.  As fish are attracted by this water flow, they are automatically captured and then lifted over the dam, allowing upstream passage for Atlantic Salmon and other species.  Involvement included all aspects of PLC and HMI system including motion control, operator interface, safety, and process control.
