A system and process is provided for controlling a steam generation and distribution system including a plurality of headers. Each of the headers is coupled to steam using devices such as steam turbines and steam supplying devices such as boilers. The process includes measuring the pressure at each header and when the pressure changes, identifying each path beginning at the particular header and terminating at a boiler, and determining the alteration of a boiler and any particular steam turbines required to restore the required pressure at the header while doing so at the least incremental cost.

A process for controlling a steam generation and distribution system which includes a plurality of headers, each of said headers being coupled to steam-using devices which create demands for steam; supply means for supplying steam to each of the headers; and steam transferring devices to transfer steam between headers so that a plurality of paths is formed between the headers, the process comprising: (a) measuring the pressure at each header; (b) when the pressure changes from a first predetermined pressure at a first header, (i) identifying each path beginning at said first header and terminating at a steam supply means; (ii) identifying each transfer means included in each said path; (iii) determining the incremental cost associated with each transfer means and with the supply means in each said path; (iv) determining the alteration of selected transfer means and steam supply means in at least one of said paths required to restore the predetermined pressure in said first header at the least total incremental cost; (c) implementing the required alterations to restore the predetermined pressure in said header.
