- Abstract:
- According to natural fluctuation characteristics of pressure signal in water distribution system， alarm threshold of pressure fluctuation in burst monitoring was determined. On this basis， the concept of burst strength was put forward as one of the parameters of hydraulic model burst simulation in optimal layout of monitoring points. According to the results of burst hydraulic simulation, layout of the monitoring network was optimized by taking the maximum leakage of burst pipes as the objective function. The coverage rate of burst pipes detection was proposed as the main index to determine the number of monitoring points. Finally, the method was applied to two cases. The calculation results showed that the monitoring points were uniformly distributed and conformed to the common sense. The detected pipelines were clear, and the basis for determining the number of monitoring points was scientific, which indicated that the method could be applied to engineering.
