Data Driven Control of Urban Drainage Systems

该项目将专注于为CENTAUR系统开发一种简单的自主水质控制算法，该算法基于EMS在Severn Trent water (STW) SSO影响现场研究站点收集的水质数据集，在这些站点监测SSOs上游和下游的水质以了解影响。本项目数据的使用已得到STW的同意。具体步骤如下。审查现有CENTAUR RTC系统、现有装置的状况和性能以及来自这些站点的可用数据集。回顾有关UDS RTC和sso对水质影响的相关文献。2. 检讨及分析多个现有污水处理厂研究地点的数据，以了解及量化污水处理厂对接收水域的影响，并为更新的污水处理厂系统订定一系列水质指标。3. 回顾目前CENTAUR在污水处理厂安装的数据集，了解现有的基于水力的控制算法（仅基于UDS水位测量）在接收水质方面的性能。根据对水位的实时测量+环境和水质数据的不同组合，为CENTAUR开发候选控制方案，以实现已定义的水质目标。考虑到传感/数据需求，与EMS员工讨论和审查备选方案，以制定首选方法。在试验现场对选定的控制方法进行虚拟测试，并与现有控制系统进行性能比较。这将以考虑可能减少环境危害和在订正的RTC控制算法下接收水质为基础。6. 在CENTAUR内更新控制算法，并在EMS指定的地点测试方法。

The project will focus on developing a simple autonomous water quality control algorithm for the CENTAUR system, based on water quality datasets collected by EMS at a number of Severn Trent Water (STW) SSO impact field study sites, where water quality upstream and downstream of SSOs is monitored to understand impacts. Use of the data for this project has been agreed by STW. The specific steps are as follows1. Review the existing CENTAUR RTC system, condition and performance of existing installations and available datasets from these sites. Review relevant literature on UDS RTC and water quality impacts from SSOs. 2. Review and analyse available datasets from range of available STW study sites to understand and quantify the impact of SSOs on receiving waters and define a range of water quality objectives for an updated RTC system. 3. Review datasets from current CENTAUR installations in STW to understand the performance of the existing hydraulically based control algorithm (based on UDS water level measurements only) on receiving water quality.4. Develop candidate control options for CENTAUR based on the use of real time measurements of water level + different combinations of environmental and water quality data for defined water quality objectives. Discuss and review options with EMS staff to develop preferred approaches considering sensing/data needs.5. Conduct virtual testing of selected control approaches at trail sites and compare performance with existing control system. This will be based on a consideration of the potential reduction in environmental harm and receiving water quality under revised RTC control algorithms. 6. Update control algorithm within CENTAUR and test approaches at sites nominated by EMS.
