Method and device for controlling a water supply network

摘要

In a water supply network (1) which comprises node components (2; 4, 5, 6, 7) and edge components (3; 8, 9, 10, 11), with water being fed in, withdrawn or stored at the nodes and via the edge components the water is transported between the node components are controlled with respect to their flow behavior for the water controllable edge components (9, 10, 11) according to a control plan (15). The control plan is determined on the basis of boundary conditions and optimized using a target function in which for Each controllable edge component is the number of its controls multiplied by a cost rate for energy consumption and / or wear of the respective edge component and then the sum is formed over all controllable edge components. According to the invention, a minimum level (hmin) is determined for each of the water-storing nodes (7). exceeding safety level (hsec) and the target radio tion for each water-storing node (7) is supplemented by a further addend in the form of a further cost rate dependent on the level, which is minimum at a level corresponding to the safety level (hsec) and maximum when the level corresponds to the minimum level (hmin).
