Alaska Electric Light & Power – Salmon Creek Digital Conversion Project – January 2014

Ivyland, PA – American Governor Company (AGC) was awarded a contract with Alaska Electric Light & Power (AEL&P) to digitally convert the UGHT controls system at the Salmon Creek Dam using Allen Bradley’s SLC 5/05 PLC platform and a color touchscreen operator interface. The conversion will retire poorly supported equipment, simplify and improve unit operation by eliminating the troublesome Speed-No-Load apparatus, achieve commonality with AEL&P’s Annex Creek in terms of PLC technology, software and spare parts; and provide enhanced DNP3 communications for compatibility with the SCADA system.

The new AGC digital control system will comply fully with IEEE 125 performance and ASME PTC-29 test codes and feature enhanced governor control and monitoring. AGC’s conversion will also allow for simplified governor diagnostics and troubleshooting to reduce and simplify maintenance. The new PLC governor is set to deliver for May 2014 with commissioning and start up to follow.
