Smart Water Grid Service Support System and Method

Smart Water Grid Operation Support Linked to Drainage Districts Based on Multi-Source Emergency Scenarios

This technology is a smart water grid service support system and method where an integrated service server links with drainage management control servers for each district to manage water levels, flow rates, and multi-source information. It calculates water management indices and optimal values based on service behavior analysis for virtual scenarios—such as water supply interruptions, pollutant inflow, and droughts—and distributes drainage management conditions to each district.

While smart water grids are next-generation infrastructure that use ICT to advance water resource distribution and monitoring, it has been difficult for operators to grasp the overall operational status of drainage districts at a glance. In emergencies like supply cutoffs, multi-source contamination, or droughts, rapid decisions on water distribution and isolation are required, yet there has been a lack of support tools to systematically provide response scenarios for each situation.

This technology collects the status of neighboring districts when an event occurs to identify intake cutoffs and flow shortages. It recalculates operational indices using multiple regression analysis to determine inter-district drainage conditions, ensuring normal flow ranges even during emergencies. It can be applied to integrated operation platforms for municipal water control centers and regional water resource agencies, enabling proactive responses to droughts and water quality incidents caused by climate change.

Key Features:

• A step where an integrated service server links with drainage management control servers for each district to manage objects provided by each server
• A step of collecting service behavior analysis results for each drainage district based on scenarios simulating water supply cutoffs, multi-source pollutant inflow, and droughts
• A step of calculating water management indices using the collected analysis results and a multiple regression-based model, and determining optimal values from these indices
• A step of broadcasting drainage management conditions corresponding to the optimal values to each drainage management control server and receiving reports on water management results from each server
