【摘要】：随着城市现代化建设的加快,供水管网作为重要的基础设施,肩负着将合格的水安全地输送到各个用户的任务,它的地位越来越重要。一旦管网发生爆管、漏损等安全事故,将会严重影响着人们的生活和生产,造成巨大的经济损失。传统靠人工和经验去监控供水管网的不安全状态已难以满足要求,为保证供水管网安全、高效运行,很多城市开始投入财力和精力去构建或完善管网动态水力模型,对管网的运行状态进行仿真模拟,为供水管网智能化管理提供了模型基础。本课题以供水管网智能化管理平台的建设为背景,在认真调研供水管网预警工作的需求后,研究设计了基于动态水力模型的供水管网预警系统。该系统基于动态水力模型仿真模拟管网的运行状态,引入SCADA系统的实时监测数据,能够对水力模型进行在线校核,确保水力模型动态的实时精准性;能够对爆管事故进行分析,得到事故的影响范围和处理方案;能够对未来需水量进行预测,为供水优化调度提供决策依据;能够对管网的压力进行预警,确保管网的安全;能够分析管网的漏失情况并进行漏失定位,为管网及时修复提供保障。经过测试,系统运行稳定,能满足供水管网预警工作智能化管理的需求。
[Abstract]:With the acceleration of urban modernization, water supply network, as an important infrastructure, shoulders the task of transferring qualified water safely to each user, and its status becomes more and more important. Leakage and other safety accidents will seriously affect people's lives and production, resulting in huge economic losses. Traditional labor and experience to monitor the unsafe state of water supply networks has been difficult to meet the requirements. In order to ensure the safe and efficient operation of the water supply network, many cities began to invest money and energy to build or perfect the dynamic hydraulic model of the pipe network, and simulate the running state of the pipe network. This topic is based on the construction of intelligent management platform of water supply network, after investigating the demand of early warning work of water supply network seriously. A water supply network early warning system based on dynamic hydraulic model is designed. The system simulates the running state of pipe network based on dynamic hydraulic model and introduces the real-time monitoring data of SCADA system. The hydraulic model can be checked online to ensure the real-time accuracy of the hydraulic model. Can carry on the analysis to the tube burst accident, obtains the accident influence scope and the treatment plan; It can forecast the future water demand and provide the decision basis for water supply optimization. To be able to predict the pressure of the pipe network to ensure the safety of the pipe network; It can analyze and locate the leakage of the pipe network and provide the guarantee for the timely repair of the pipe network. After testing, the system runs stably and can meet the demand of intelligent management of the water supply network early warning work.
