Water transportation pipe network calculation method based on node parameterization technology

Abstract

The invention discloses a water transportation pipe network calculation method based on the node parameterization technology, and relates to the field of water conservancy. The method comprises the steps of initializing a pipe network system to be tested; decomposing the initialized pipe network system to be tested into parameterization nodes and a calculation pipeline connected between two adjacent parameterization nodes; by calculating pipeline connection parameters and node connection parameters, connecting and combining the calculation pipeline with the parameterization nodes; judging whether the current calculation time is a model control end time or not, and if yes, completing calculation of the whole pipe network with pressure in the pipe network system to be tested at the current time; if not, executing the step 1 again till the current calculation time is the end time, and completing calculation of the whole pipe network with pressure in the pipe network system to be tested at the current time. According to the water transportation pipe network calculation method, on the basis of pipe network decomposition and rapid calculation, analog calculation precision can be well ensured, and the calculation result is as good as that of business software Hammer.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a method for calculating a water delivery pipe network based on node parameterization technology. Background technique [0002] The water supply system is an important infrastructure of the city, which is responsible for transporting the water body from the water source to the water user, so as to meet the urban living and production water demand. With the rapid development of cities, the demand for urban water supply capacity is getting higher and higher, and the construction of water supply systems is becoming more and more complicated. On the one hand, there are many operating conditions of the pipeline network under pressurized water delivery, and management and control are difficult; on the other hand, the safe and efficient operation of the water delivery pipeline network is crucial to the normal operation of various urban water demand departments. In addition to the desig...

Problems solved by technology

Many calculation models are still mainly based on the energy equation and balance theory, and it is difficult to simulate the hydraulic transition process, especially when there are many internal adjustment projects such as pumping stations and air control valves, and the pipe network connections are complicated, either the functions are not compatible, or the models are not open source. There are many problems such as cumbersome model data management and high simulation calculation costs
