- Abstract:
- The monitoring network of water supply system is the prerequisite to obtain pipe burst data for effective pipe burst monitoring. The pipe sections with large flow rate are often the distribution mains, and the burst of these pipes is more harmful. In the case of the same flow rate in these pipe sections, a longer length means a greater possibility of pipe burst, more water consumers along the line, and more difficulty in burst location. Therefore, this paper introduced two important parameters including pipe section flow and pipe length to optimize the location and number of new pressure monitoring points, so as to improve the burst monitoring coverage of important pipe sections. The optimization problem was solved by using heuristic algorithm, and the method was verified in a district of a large city pipe network in southern China. Compared with the results without considering the importance parameters of pipe sections, when 5 pressure monitoring points were added after considering the importance parameters, the increased monitoring rate raised from 41.9% to 54.8% for DN400-600 pipe sections and from 28.6% to 78.6% for DN700-1 800 pipe sections. When 25 pressure monitoring points were added, the increased monitoring rate of DN700-1 800 pipe sections raised from 78.6% to 100%, and the important pipe sections were monitored first.
