| (54) | Method and equipment for controlling a multipoint fluid distribution system |
| (57) It comprises taking pressure measurements in a point previous to the consumption
points by means of a piece of control equipment and performing the following steps
in sequence: a) acquiring a successive series of supply pressure values (Pi) measured in said previous point; b) varying the pump rotating speed in response to a pressure variation detected in said previous point; c) detecting that at least two of said pressure values (Pi1), (Pi2) measured in said previous point change (increase or decrease) and obtaining a curve of demand (10) by calculating the coefficients of a known mathematical function descriptive of said curve of demand, making said coefficient calculations from said measured pressure values (Pi1), (Pi2) and of corresponding calculated flow rate values; d) determining a consumption point (12) by intersecting the curve of demand with the y-axis and e) adopting a pump rotating speed providing a pump setpoint pressure, depending on said consumption point (12) determined in step d), restarting steps b) to e) in the event of another pressure variation in the demand. |
