Control System Upgrade Centralizes Plant Operations

摘要

Purdue University's central utilities plant has four boilers that provide 710,000 1b/hr of saturated steam for power generation and heating. The plant also has two 40 MW steam turbines, five chillers, a cooling tower, air compressors and potable water wells. The initial decision to embark on a controls upgrade was driven by a desire to centralize and optimize control, boost reliability and to meet Y2K requirements. Upgrade of the control system is being carried out in stages, as funding becomes available. A contract systems integrator provided the initial control philosophy, programming and graphics.
