This basic module enables the user to model, design and optimize his Gas network using NEPLAN’s famous graphical interface and NEPLAN’s powerful, up-to-date calculation algorithms to address a wide range of applications.
General Characteristics
- Powerful, up-to-date calculation algorithms (including Newton-Raphson and Hardy-Cross)
- Simulation of any kind and size of networks
- No restriction on number of nodes and pipes
- Simultaneous calculation of any number of partial networks (independent networks)
- Sophisticated valve and regulator models
- Calculation with load factor profiles and profiles for node demand
- Import of measured consumption data
- Changing demands through global, regional or simultaneity load factors
- To each pipe any number of line loads can be connected (e.g. houses, heating, industrial , etc.)
- The head loss characteristics of the pipes are calculated according to Darcy, Prandtl-Colebrook and Hagen-Poiseuille
- Simultaneous calculation of different pressure zones (high, medium and low pressure)
- Simultaneous calculation of compressible and incompressible gases (high and low pressure)
- Free definition of load libraries (heating, cookers, industrial loads, etc.) with different simultaneity factors
- Temperature dependent loads are considered
Results
Upon calculations, results are automatically displayed on the single line diagram while their content and graphical information can be customized. Result evaluation and processing is easier due to visualization functions:
- Coloring according to variable ranges (e.g. velocity, flow, pressure-losses, pressure etc.)
- Highlighting of overloaded elements (e.g. velocity v > v max)
- Line width proportionaly to many variables, including the flow and diameter
- Result output to an excel like table sheet, with copy/paste possibilities to MS-Excel
- Output to ASCII files or SQL database for further evaluation (e.g. MS-Excel)
- Display results in a sophisticated chart manager (e.g. bar or line chart)
- Result boxes can be moved, deleted, sized, colored and hided
- Self-defined result output: the user can select units, variables, font, precision, placement
- Comparing results was never easier: Results from other variants can be displayed in the same result label and in the same chart
