Definitions

  • the invention relates to the general field of waste water networks.
  • the invention relates in particular to the real-time management of such a network.
  • a waste water network typically includes transport works, for example pipelines, intended to bring water to a treatment plant and storage facilities such as storm basins.
  • the network may also include automation and actuators such as pumps and valves, to influence the flow of water in the network.
  • a pump can be controlled depending on the level of water in a tank.
  • the control commands of the actuators have an influence on the performance of the network.
  • a high trigger level for a discharge pump of a storm basin limits the amount of water discharged into the downstream network and thus limits the risk of flooding or spilling into the natural environment in the downstream network.
  • a high level also limits the amount of water that can still be stored in case of heavy rain. The risk of spilling into the natural environment upstream of the storm basin is thus increased.
  • the real-time management of a waste water system consists in adapting actuator control instructions to a rain event, in order to improve network performance.
  • the performances are for example characterized by the location of urban floods and the quantity of spill in the natural environment or the quantity of energy used during this management.
  • it is known to adapt the control commands of the actuators to predicted or measured rain.
  • the sanitation network of Seine-Saint-Denis described in the document «Real-time operation of the sewerage network of Seine-Saint Denis», JM Delattre, presented at the conference "The management of the drenaje unrbano", Barcelona, 2004 , is based on a scenario approach.
  • a typical rain approaching as close as possible to the actual and future rain in the area is selected from a sample of 27 rains.
  • each rain-type corresponds a set of instructions of the actuators of the network.
  • a wastewater system may include many structures and actuators.
  • the inventors have found that in practice, a network almost always included at least one structure or an actuator unavailable or operating at reduced capacity.
  • the unavailability may be due for example to a default or to a jobless for maintenance.
  • the sets of setpoints are predetermined according to a model of the network which represents the nominal state of the network.
  • the setpoints used can lead to an underperformance of the network when its state is not the nominal state.
  • the aim of the invention is to provide a method of controlling a waste water network, having improved performance.
  • the invention aims to use a set of instructions that leads to improved performance.
  • the invention relates to a method of controlling a wastewater network, said network comprising actuators able to influence water flow rates in the network, the behavior of the actuators depending on instructions, the method comprising the steps according to claim 1.
  • the deposit set is selected not only according to the type of rain but also according to the current state of the network.
  • the list of sets of set contains a set of instructions allowing to obtain improved performances, whatever the state of the network.
  • the step of determining at least one new set of setpoints includes determining a new set set for each type of rain in the list of rain types.
  • the step of determining at least one new set of instructions may comprise the execution of an optimization algorithm.
  • the step of determining at least one new set of setpoints includes determining the network model based on a nominal network pattern and second status information.

  • the program according to the invention can be downloaded in particular on an Internet type network.
  • the recording media may correspond to an integrated circuit in which the program is incorporated, the circuit being adapted to execute or to be used in the execution of the method in question.
  • the figure 1 represents a network 1 of waste water, intended to convey rainwater from an agglomeration to a purification plant 4.
  • the agglomeration is divided between a north zone 2 and a south zone 3.
  • the network 1 comprises reservoirs S1 to S7, pumps P1 to P10, buffers T1 to T15, pipes represented by arrows, and a control device 8.
  • Each reservoir S1 to S7 also comprises a sensor. level for measuring the height of water h in the tank.
  • circles 5, 6 and 7 represent discharge points towards the natural environment, respectively in a first stream A5, a second stream A6 and a third stream A7.
  • the figure 2 is a graph which represents the behavior of the pumps P1 to P10 of the network 1.
  • the flow rate Q of a pump is controlled according to the height h of water in the associated reservoir, measured by a sensor. Thus, if the height h is less than h stop , the pump is stopped. The water level will then go up to reach h start . The pump then starts at flow Q min . Two possibilities then arise. If the weather is dry, the flow of waste water entering the tank is less than Q min and the water level will drop until it reaches h stop , which will cause the pump to stop. If the weather is rainy and the waste water flow is greater than Q min , the water level will continue to rise and the pump will then increase its flow, until it stabilizes at the incoming water flow, or until reaching its maximum flow Q max .
  • the water height h max at which the pump reaches its maximum flow rate Q max constitutes a control setpoint which indicates the tendency which one has to store in the tank (if h max is high) or to pump rapidly towards the downstream to avoid storage (if h max is low).
  • the value of h max influences the performance of the network. Indeed, a high value of h max limits the amount of water discharged in the downstream network and therefore to limit the risk of flooding in the downstream network. However a high value of h max also limits the amount of water that can still be stored in case of heavy rain. The risk of spilling into the natural environment is therefore increased.
  • the control device 8 is for example located in a control room of the network manager 1.
  • the figure 3 represents the control device 8 in more detail. It presents the architecture of a computer and comprises in particular a processor 9, a non-volatile memory 10, a random access memory 11, and a communication interface 12.
  • the processor 9 allows the execution of a control program of the network 1 stored in the memory 10, using the RAM 11.
  • the memory 10 is an information carrier within the meaning of the invention and the control device 8 constitutes a control device within the meaning of the invention.
  • the control device 8 stores, in the memory 10, a list of rain types, a list of states of the network, and a plurality of setpoints for the pumps P1 to P10.
  • the list of types of rain includes a homogeneous rain called "PLHO", and a stronger rain on the south zone 3 called "PLFS”.
  • the state list of the network comprises a nominal state EN, in which the tanks S1 to S7, the pumps P1 to P10, the buffers T1 to T15 and the mains of the network 1 all function normally, and a first state of unemployment EC1, in which an intervention on the network requires to limit the flow rate Q max pumps P1 and P2 at half their nominal flow Q max .

  • the figure 4 represents steps of the control method implemented by the control device 8.
  • the control device 8 obtains information on the current or expected rainfall on the agglomeration, for example from a weather station.
  • the control device 8 also obtains information representative of the current state of the network 1, for example by consulting an intervention planning system or by consulting sensors capable of generating such information, for example a fault sensor of a pump.
  • step E20 the control station 8 selects a type of rain from the list of rain types that best matches the rain determined in step E10.

  • step E30 the control device 8 selects, in the list of set sets, the set of setpoints corresponding to the type of rain and the state of the network selected in step E20. For example, if the rain PLSF and the nominal state EN have been selected in step E20, the controller 8 selects the set of set C2 in step 30.
  • step E40 the control device 8 sends the pumps P1 to P10 messages indicating the instructions to be used, that is to say the instructions of the set of set C2 in the case mentioned above.
  • Steps E10 to E40 can be repeated.

  • the control device 8 can consult an intervention planning system or sensors capable of generating such information, as in step E10.
