The invention discloses an optimal arrangement method for
urban water supply
pipe network flow monitoring points. The method comprises the following steps that a
water supply pipe network hydraulic model is constructed; a
water supply pipe network flow monitoring point optimal arrangement model is constructed, constraint conditions of the model are a pipe network node flow
continuity equation, a pipe network node
water pressure constraint condition and a pipe network
energy conservation equation, and a
sensitivity equation of pipe network node flow to pipe network node pressure is established;Pearson
correlation analysis on the
sensitivity equation is adopted in the optimized arrangement model for calculating the flow monitoring points of the
water supply pipe network, a simple normalization equation is solved, the arrangement positions of the
pressure monitoring points and strong correlation points of the
pressure monitoring points are solved, and an optimal flow monitoring point scheme is determined. According to the method, the arranged
pressure monitoring points can well reflect the change condition of the node pressure, the reliability of the monitoring points is improved, meanwhile, the node range capable of being monitored by each pressure monitoring device can be determined, the requirements for representativeness, comparability and feasibility of point distribution are met, and
blindness of selection of the pressure monitoring points at present is reduced.
