供水管网故障诊断的流量监测点遗传优化布置

针对供水管网爆管故障诊断中流量监测点的布置问题，建立了考虑流量敏度的监测点优化布置模型，并采用整数编码遗传算法进行优化求解。针对遗传染色体在初始生成以及交叉、变异等遗传操作中易产生编码重复的问题，提出了新的改进算法。实例分析结果表明：基于本文方法布置优化后的监测点流量信息的诊断效果较为理想，在漏水量较小的条件下，基于优化的流量监测点信息对爆管管段的正确检出率较高，优于基于水压监测点信息的诊断结果。

Genetic Optimization Arrangement of the Flow Monitoring Points in Water-Supply Network Fault Diagnosis

This paper studies the arrangement of flow monitoring points in water supply pipe network fault diagnosis. The optimization arrangement model considering the flow sensitivity of monitoring points is established and the integer coding genetic algorithm is adopted to solve the optimization problem. Considering the code duplication problem produced by genetic operation of initial generation, crossover and mutation, a new improved algorithm is proposed. The analysis result of an example shows that diagnosis effect of the flow information of the monitoring points based on the optimization arrangement method proposed in this paper are better, especially under the condition of small amount of water leakage, the detection rate to burst pipeline for the information about flow monitoring points based on optimization is higher than that of water pressure.
