NEPLAN Water

From the NEPLAN web site:

NEPLAN Gas, Water, District Heating – Analysis tool for gas, water and district heating networks.

NEPLAN is used to analyses, plan, optimize and manage gas and water pipeline networks. Any desired number of nodes and tubes can be quickly and interactively entered, computed and evaluated. NEPLAN is continually being enhanced, not least due to supportive empirical feedback and a fruitful dialogue between satisfied users and our development people. NEPLAN’s modular concept means that network planners can put together a planning system specifically tailored to their own individual needs.

• All equipment and pipes can be entered graphically and/or table oriented (like in a excel sheet)
• A single line diagram can easily be generated through a very user friendly CAD systems.
• There is no restriction on drawing sizes and number of nodes and elements.
• Extensive editing functions like undo, redo, delete, copy, move and zoom for processing the network diagram are available. An element can be moved from one node to an other node without deleting the element.
• OLE functionality: Data and graphic can be easier.
• The element data are entered in dialogs, with plausibility checks provided. A coloring tool helps to show which data is needed for which analysis (e.g. time simulation)
• Integrated Variant Manager (insert, delete, append, compare variants, compare results, etc.).
• ASCII file or SQL database oriented import/export functions for exchanging network data, topology data and load data are available.
• Interfaces to external programs (e.g. measured data acquisition systems) can be implemented.
• Import of a geographic map as a background graphic, for easier schematic capturing.
• Import of almost any raster and vector graphic files (e.g. PCX and DXF files).
• Graphics can be exported as raster files (e.g. JPG, which can be used in any internet web browser).
• Option for combining and separating networks. Any number of independent network areas and zones are possible. Each element and node can belong to any independent area and zone.
• Extensive functions for network statistics and network documentations are available.
• A state of the art library manager with extensive libraries for each element type facilitates data entry.
• All computation modules access a shared database.
• Integrated chart manager allows to analyze and compare all results from all variants.
• Languages for graphical user interface and manual: English, Spanish, German, Italian, French
• Calculation with load profiles (e.g. one day, one week etc.).
• Import of measured consumer data from an existing in-house database.
• Loads (consumers) can be changed through 3 different load factors (general, regional or simultaneity load factors).
• To each pipe any number of line loads can be connected (e.g. houses, heating, …). Importing of consumers from existing databases (e.g. from an accounting database )is possible.
• All load and simultaneity factors of the line loads are considered during the calculation.
• The consumptions can be entered in different units (e.g. l/s m3/h, kW, t/h, etc).
• Simultaneous calculation of multiple partial networks.
• Powerful, up-to-date calculation algorithms. Two algorithms are included (Hardy-Cross and Extended Newton Raphson). The Extended Newton Raphson allows in the future to add new models independent of their complexity.
• Calculation of centrifugal and circulation pumps, reservoirs, valves, fittings etc.
• Calculation of multiple pumps and reservoirs.
• Calculation with different water temperatures.
• The heat loss characteristics of the pipes are calculated according to Prandti-Colebrook and Hagen-Poiseuille.
• Profiles for reservoirs (for calculation of filling and emptying process) and loads.
• Libraries for load types with different simultaneity factors.
