Subproject 1: Development of the system basics for building and testing the PaT-system, preparation of guidelines, project coordination

Contact:

Prof. Dr. F. Wolfgang Günthert, Universität der Bundeswehr München, Institute of Hydro Sciences, Chair of Sanitary Engineering and Waste Management, Werner-Heisenberg-Weg 39, 85577 Neubiberg

Abstract:

The test environment for the system development is defined at the beginning of the project. Therefore, the specific constraints of the application partners are defined and appropriate pilot areas are selected. For the comparability of all collected data, it must be transferred into a common data structure. For the different development stages of the PaT-system, as well as the used components, extensive testing on a test stand (test track + test facility) is required. Based on the results of the pilot testing and the verification of the developed system to the network a guide for professional associations (DVGW), water suppliers, municipalities and planning agencies will be created on the basis of a final report that shall be available for the aggrieved parties.

Subproject 2: Development of a PaT-unit for pressure reduction in the water distribution system for producing electrical energy

Contact:

Traugott Ulrich, KSB Aktiengesellschaft, Johann-Klein-Str. 9, 67227 Frankenthal

Abstract:

In this subproject a PaT-system is developed, which consists of the pressure control and energy recovery unit and a superimposed control for the "smart" pressure management. Further, a PaT-unit (test facility) and the basis for internal control of this unit are developed as well as algorithms for optimal pressure regulation in the water distribution network.

Subproject 3: Development of a remote monitoring and remote control system

Contact:

Dr. Stephanie Schraml, SCHRAML GmbH, Herxheimer Straße 7, 83620 Feldkirchen-Westerham

Abstract:

This subproject comprises decentralized collection, transfer and processing of data in the network of water utilities. There is need to develop software and hardware components, on the realization of various data interfaces, the integration of sensors, control units and analog / digital input / output signals at decentralized stations in the network and allow secure and efficient data exchange between the communication units (Com-units) in the network (including cross-communication) and the central control system. This has to happen in "near real time" because of the dynamics in the water supply system. The exchanged information must be used to derive closed-loop control logics and commands for the intelligent pressure management in a dynamic model balance for the control of the hydraulic PaT-units (test facility or field trial facilities).

Subproject 4: Development of model-based control strategies for the optimization of pressure and energy generation

Contact:

Dr. Thomas Krätzig, Dr. Krätzig Ingenieurgesellschaft mbH, Süsterfeldstraße 81, 52072 Aachen

Abstract:

The aim is to connect the demand-driven optimized pressure control for the grid with the maximum energy generation by the PaT-unit (test facility, later field test equipment). For this purpose, the "near-real-time" use of water network simulation models in conjunction with optimization strategies will be tested. Control strategies of the "intelligent" pressure management based on the measured real-time in physical quantities such as pressure and flow rate as well as model-based data will be developed and tested. A more efficient control of the pressure head in the water distribution networks with ("lossless") energy recovery and an appropriate supply will be achieved at the same time.

In the subproject, further data for potential energy generation, investment costs, as well as for proposals for the use of energy in island operation will be collected. The benefits for water suppliers from the use of intelligent pressure management systems with energy generation and recovery are summarized in form of a guideline.

Subproject 5: Conception and testing of a PaT-prototype

Contact:

Thomas Tinnes, AWA-Ammersee Wasser- und Abwasserbetriebe gKU, Mitterweg 1, 82211 Herrsching

Abstract:

After developing and testing the "novel" system, it has to be installed in a real network. After a successful start-up, the system must be calibrated and optimized, and its performance must be adapted for continuous operation. It is intended to install a built-in bypass pump as a turbine for regulation instead of a pressure reducer. Afterwards, the control of the system should take place by built-in pressure sensors in order to test a decentralized pressure management. Network data from GIS and from process control systems will be provided by the network operators.

Subproject 6: Operating system adaptation and optimization

Contact:

Derk Buchsteiner, Wasserversorgungszweckverband Perlenbach, Am Handwerkerzentrum 31, 52156 Monschau

Abstract:

For enabling the application of the designed system in other companies in the water sector, a detailed compilation of the technical and administrative boundary conditions will be carried out. Topography, population density, hydrogeology and climate act a decisive part. Also the supply structures (centralized/decentralized) and network size will be considered here.
