论文摘要
本文介绍了澳大利亚Robinvale高压灌溉水系统（RVHP）的运营管理案例研究。根据可用数据集，研究了使用校准的液压模型进行改进的泵设定点选择。第一步是实施测量流量和压力数据的预处理，以识别数据中的错误以及可能的错误传感器。通过使用处理的压力和流量数据，通过校准的管道粗糙度高度值更新了Epanet液压模拟模型。然后，使用校准模型选择了新的泵设定点，鉴于实际测量的需求使网络中的压力受到所需的客户服务标准的约束。基于为期两天的模拟，据估计，通过应用新的泵设定点可以实现4.7％的抽水能源成本节省4.7％的温室气体排放。
This paper presents a case study of the operational management of the Robinvale high-pressure piped irrigation water delivery system (RVHPS) in Australia. Based on datasets available, improved pump setpoint selection using a calibrated hydraulic model is investigated. The first step was to implement pre-processing of measured flow and pressure data to identify errors in the data and possible faulty sensors. An EPANET hydraulic simulation model was updated with calibrated pipe roughness height values by using the processed pressure and flow data. Then, new pump setpoints were selected using the calibrated model given the actual measured demands such that the pressures in the network were minimized subject to required customer service standards. Based on a two-day simulation, it was estimated that 4.7% savings in pumping energy cost as well as 4.7% reduction in greenhouse gas emissions can be achieved by applying the new pump setpoints.
