Mass. Water Resources Authority – Cosgrove – October 2012

Ivyland, PA – American Governor Company (AGC) was awarded a contract by Dewberry Inc. to refurbish a 10-year-old Digital Governor/Automatic Controls System for two 2.5 MW Kaplan turbine/generators and ancillary systems at Massachusetts Water Resources Authority‘s (MWRA) Cosgrove Station to achieve the functionality envisioned in the original specification. AGC will achieve two parallel and fully independent control systems within the existing common enclosure while reusing the existing hardware and all field wiring, to the greatest extent possible.

Three deficiencies in MWRA’s current execution of the control that will be rectified by this effort include replacement of the digital governor proportional valves and their feedback mechanisms, removal of all vestiges of the previous attempt to create Redundant PLC Operation and the creation of two independent control systems within the same enclosure, and creating a PLC program that meets MWRA requirements for reliability, functionality, remote reporting, information display and remote control. This project will be completed in March 2013.
