| titleOfInvention | Method for identifying water pressure transfer relation between nodes of water supply network |
| abstract | The invention provides a method for identifying the water pressure transfer relation between nodes of a water supply network. The method comprises the steps that Pearson correlation analysis is conducted on water pressure of the nodes of the water supply network according to measured data, and important nodes which are in strong correlation with some nodes in the network are selected, wherein the important nodes are called center nodes, and the nodes which are in strong correlation with the water pressure of the center nodes are called correlated nodes; one center node and a plurality of correlated nodes form a sub-network, and the water supply network is divided in this way; in each sub-network, the water pressure value at the center node is regarded to be determined by water pressure values at the correlated nodes of the center node, and the relation means water pressure transfer; a linear regression model is established to quantitatively describe the water pressure transfer relation, and parameters of the model are estimated according to the measured data. On the condition that the detailed structure, elements and parameters of the actual water supply network are not clear but water pressure sensors are reasonable in distribution, the method can be used for high-accuracy identification of the water pressure transfer relation between the nodes and has potential to be applied to water pressure control of the water supply network. |
