Central Utilities Plant Turbine Controls Replacement for San Jose State University.    

San Jose State University provides support services to buildings on its campus. The main campus is home to over 50 major buildings on 19 city blocks in downtown San José, CA.

The underground District Utilities is connected to a sophisticated and “green” central energy plant; from which power, heat, and cooling is dispatched to main campus buildings; at a global efficiency as high as 85%. The control system hardware for the gas turbine were nearing end-of-life and in need of replacement.

How We Did It

The University was seeking to modernize the turbine control system by replacing the PLC hardware and software to the latest version of GE programmable automation controller. Harris Group understood the unique challenge associated with complex retrofit projects and met the challenge by developing accurate record drawings, gathering the necessary field information, and dedicating a core engineering team to come up with a seamless plan for migration to the new GE PLC RX3i platform.

Harris Group provided field investigation, design factory acceptance testing, site acceptance testing, program conversion and on-going field support for the DCS replacement of existing gas turbine control systems. We converted the system from obsolete GE 6 system to new RX31 GE PLC with DCS software.

Harris Group teamed with a local panel fabrication shop and veteran-owned electrical contractor to provide upgrade services to SJSU.  We both managed and executed the field investigation, executed the factory acceptance testing and completed the final commissioning.  Harris Group staff provided the final PLC logic and DCS programming to ensure the new control system was complete and functional.  Our staff continue to support San Jose State University with software upgrades and programming for their central utilities plant, turbine generator, and chillers.
