Description

Technical Field [0001] The present invention relates to an operation management control system,

The present invention relates to a waterworks operation management control system and a control method thereof. More particularly, the present invention relates to a waterworks operation management control system and a control method thereof, more specifically, to accurately predict supply and demand information of an outflow amount of a waterworks workplace and calculate an operation management schedule for 24- And more particularly, to a waterworks operation management control system and a control method thereof that can operate a plant at a maximum water supply and a minimum energy cost in real time.

In the operation of the waterworks business, about 95% of the electricity costs are spent for pump operation, and the electricity cost is increased due to the increase of electric power charges every year. Therefore, Standards.

Dereco's Aquadapt is the only pumping system optimization algorithm that works with SCADA (Supervisory Control and Data Acquisition).

In this study, the water demand forecasting model estimates the future water demand based on the past water supply performance and transfers the result to the hydraulic analysis model. And the pump operation cost is calculated by considering the pump efficiency and operating condition through the pipe network analysis.

The computed operating cost of the pumping station is evaluated by the optimal control model to satisfy the given condition. If the given condition is not satisfied, the value of the pump network is reevaluated by changing the combination of the pumps and redoing the pipe network analysis.

In this way, the optimal control model and the hydraulic analysis model perform iterative operations to find the optimal solution that satisfies the objective function value while satisfying the given boundary conditions and constraints.

On the other hand, since the domestic waterworks facilities are different from the facilities of waterworks operators in other countries, when the above-mentioned technologies are applied in Korea, simplified pump modeling can be used to present pump schedule schedules different from actual pump operation, It is difficult to optimize for a specific time, or when demand change is large at a specific time, it is difficult to actively cope with the change.

Accordingly, the waterworks operation management control system and the control method of the present invention predict the supply and demand information of the outflow amount of the waterworks workplace relatively accurately and calculate the operation management schedule for the 24-hour optimum operation, A water supply operation management control system and a control method thereof that can operate at a maximum water supply and a minimum energy cost.
