Ivyland, PA – American Governor Company (AGC) has been awarded a contract for the East Bay Municipal Utility District (EBMUD) Pardee Powerhouse. For this project AGC will supply and install two new digital governor / control systems.
Although continuing support for the existing Woodward 517 digital controls was being provided by AGC, the customer elected to replace these proprietary systems with PLC-based digital controls so they can achieve platform commonality with other control systems in the plant and be able to maintain and modify the systems on their own. The new systems will include governing, unit start/stop control and monitoring functions, as well as automatic synchronizing and VAR/PF control functions.
The new cabinets will be designed as drop-in replacements for the existing cabinets to simplify installation. New color touchscreen operator panels will eliminate the need for numerous external meters and switches. The existing hydraulic system and electrohydraulic control valve manifold will be retained. A new position feedback device will be added for redundant position feedback. The existing redundant speed sensing capability and devices will be retained.
Site services provided by AGC will include installation, start-up, testing and training services. Delivery will occur in November 2009, with installation and commissioning completed in January 2010.
