Optimal Distribution of Pressure Measurement Points in Water Distribution Networks

The pressure similarity method is proposed to get the optimal distribution of pressure measurement points for water distribution networks. This kind of optimal distribution is mainly composed of two steps. Firstly, the pressure similarity coefficients of any two nodes should be calculated to obtain the similarity coefficient matrix. Then all the nodes can be grouped through clustering analysis on the matrix and the pressure measurement points can be chosen out. The application on a practical network shows that the pressure similarity method can reflect the regional characteristics of network pressure and the result is reasonable. This method is very useful for network further study such as state simulation, optimal scheduling and accident early-warning.
