The impedances change of users and trunks in the pipe network with multiple heat sources on the influence of the location of hydraulic intersection point

A model for multi-heat source circle pipe network was established, and the location of the hydraulic intersection was calculated and analyzed applying the method of matrix algebra. By increasing the impedances of the users or supply and return trunks which are associated with the hydraulic intersection point, the locations of hydraulic intersection points were compared. It was found that it is not effective if we only rely on increasing the impedances of the users or supply and return trunks which are associated with hydraulic intersection point to change the location of the hydraulic intersection point.
