Study based on operation by valve control for water distribution network

摘要

The pressure of water distribution network is one of the major cause which make the network fault, by the regulating valve the local pressure is regulated. The regulating length is obtained through the sensitivity of the coefficient of friction resistance to node pressure, through alteration of the opening of valve, the local pressure is regulated and verification is by example. The result show the local pressure is regulated through the regulation which provides a solution for the urban distribution network operation.
