Abstract:
An adaptive, predictive control system for outlet pressure adjustment of at least one district regulator of a fluid distribution system so as to satisfy a real-time demand for a fluid distributed by said fluid distribution system comprising:intelligent controller means for controlling said at least one district regulator comprising means for communicating with at least one intelligent monitor means disposed in said fluid distribution system at a distance from said at least one district regulator, means for adjusting an outlet pressure of said at least one district regulator, means for sensing a fluid inlet pressure and a fluid outlet pressure of said at least one district regulator, and for sensing ambient temperature proximate said at least one district regulator to predetermine an initial output pressure set point for said at least one district regulator;said at least one intelligent monitor means comprising communication means for communication with said controller communication means, monitor pressure sensing means for sensing a fluid pressure in said fluid distribution system proximate said at least one intelligent monitor means, and monitor ambient temperature sensing means for sensing a monitor ambient temperature proximate said at least one monitor means; andan adaptive means operating in communication with said intelligent controller means, said adaptive means generating a prediction of fluid demand and a corresponding district regulator fluid outlet pressure setting.
