- Abstract:
- Regional co-scheduling of pumping stations can predict sewage quantity changes in real time, balance transferred quantity through staggered peak transfer during peak water consumption, and spare out the storage space through pre-precipitation during low peak water consumption, so as to better guarantee the operation of sewage pipe network at low water level, reduce the risk of sewage entering the river, increase the amount of water treated in the sewage plant, and realize the whole collection of stipulated sewage. In terms of efficiency, the system provides the best pump station water level control value and the corresponding pump operation mode to reduce transfer energy consumption and increase response speed, through real-time calculation and analysis engine, namely drainage system load analysis, water balance analysis, water level pre-adjustment analysis and overflow risk analysis based on real-time data collection, transmission and aggregation.
