Ivyland, PA – American Governor Company (AGC) has been awarded a contract with New Brunswick Power to retrofit the first of three Woodward 517 Digital Controllers with a more robust design to deliver in early 2014 with installation and commissioning services to follow. AGC will develop a design to duplicate and, in some instances, correct the functionality of the 517 controls. A Human Interface Machine (HMI) will be provided for easy operator maintenance while existing Blade Angle and Gate Position feedback devices will be replaced with better responding solid state devices. AGC will also convert existing distributing valves to EHI Pilot Stage control.
Beechwood Generation Station, one of seven hydroelectric dams operated by New Brunswick Power on the Saint John River, has a capacity of 113 MW. The new controls system provided by AGC will be compliant with ANSI/IEEE Std 125 “IEEE Recommended Practice for Preparation of Equipment Specifications for Speed-Governing of Hydraulic Turbines Intended to Drive Electric Generators” and ASME PTC-29 “Speed Governing Systems for Hydraulic Turbine Generators.”
