improved system for estimating water flows at the boundaries of a subnet of a water distribution network

摘要

the invention relates to a system for measuring water flows in a subnet of a water distribution network. the system comprises a plurality of sensors, for example pressure sensors, in the network. the system also comprises communication links between the sensor and a computing device, and a measurement acquisition system. the computing device is configured to retrieve measurement values, directly or through the measurement acquisition system; use measurement values to determine values of control variables of a model of the water distribution network that minimizes the residue values between measurement values and predicted physical values in the network; then, use the model parameter with the referred values of the control variables to calculate the water flows at the subnet limits. figure 3
