Newly-added monitoring point arrangement method and device for checking hydraulic model of water supply network

The invention discloses a newly added monitoring point arrangement method serving water supply network hydraulic model checking, which comprises the following steps: step 1, calculating to obtain a pressure sensitivity matrix and a measurement node set of each node of a water supply network according to a standard working condition of a water supply network hydraulic model; step 2, constructing a target function for calculating the monitoring effect distance between the to-be-arranged node and the existing monitoring point, and taking the node corresponding to the minimum solution of the target function as a newly added monitoring point; and step 3, after the newly-added monitoring points are added into the existing monitoring points, the process of the step 2 is repeated until the arrangement state of the newly-added monitoring points meets a termination condition. The invention further provides a newly-added monitoring point arrangement device based on the method. According to the method provided by the inv
