Calibration of an electronic model of a water supply system
(through the example of the water distribution network of Salavat city)

Summary

In accordance with the RF legislation within the frames of the water supply schemes development for the Russian cities designing an electronic model of a water supply system is envisaged. In order to obtain trustworthy results of modeling the model verification is required that is carried out by the calibration on the basis of operation and statistic data of the water supply system. The action of the electronic model calibration through the example of the Salavat water distribution network is described (Republic of Bashkortostan). The calibration was aiming at maintaining hydraulic head at the nodal points of the design model according to the assumed calculation as well as maintaining water source flows according to the assumed estimation hour. The calibration of the electronic model of the water supply system was carried out by varying the maximum values of steel and cast iron pipeline roughness that corresponded to their maximum working lifespan. The calibration process involved a considerable amount of hydraulic calculations (256). The mean total difference of hydraulic head between the estimated values and actual measurements was 4.03%; the mean total difference of water source flows – 0.31%. With the purpose of the calibration process automation an algorithm based on VBA language with the use of Excel tables and ActiveX library of «ZuLuNetTools» was developed. The developed algorithm of automated calibration of the electronic model is applicable to «ZuLu» Russian software.
