Exemplary systems and methods for monitoring a current state of a spatially extensive supply network having at least one control station that monitors and controls the supply network and a plurality of sensors that transmit measurement values relating to operating behavior to the at least one control station. Current measurement values are measured at positions on the supply network corresponding to each sensor. Each sensor analyzes measured signal variations and signal trends of the measured current values via an evaluating unit. The measurement values of each respective sensor are transmitted to the at least one control station in data packets at a defined time. At each respective sensor, when the analysis detects an abnormal measurement signal variation, a frequency of transmission of the respective sensor and each adjacent sensor is increased, the respective sensor transmitting the measurement values to the at least one control station or to adjacent sensors to which the respective sensor is connected to through a common supply line and which measure an identical or physically similar quantity.

System and method for transmitting measurement signals in spatially extensive supply networks

An exemplary arrangement for determining set point values for controllable elements in a network that includes a management system for driving elements of the network and a plurality of processing units. The arrangement also includes at least one simulation unit with a simulation environment for generating a hydraulic simulation model of the network, and an optimization unit with an optimization environment for converting and simplifying the hydraulic simulation model. The optimization environment receives exported data from the simulation environment, generates a simplified optimization model from the exported data through an algorithm that is implemented through program code executed by a processor, and uses the optimization model and at least one of received additional data and measurement and field data to calculate optimized flow charts as temporally changeable set point value series for driving elements in the network and providing the driven elements to the management system.
