BelVis GAS offers the necessary support for routine daily business including all the relevant processes and procedures involved in the gas industry.
BelVis GAS is highly flexible when importing load data.
BelVis imports the load data from remote meter reading systems from metered extraction points or metered feeder points. In the gas sector these are customers with flow measurement clocked at hourly intervals or measurements at interconnection and feeder points. The smoothest import is performed by the remote meter reading module BelVis SODA because it writes the data directly to the BelVis database. Needless to say, BelVis is also compatible with other telemetry systems, such as Elster, Görlitz, Tritschler, and Wieser, directly via their file interface via which BelVis imports automatically.
Powerful plausibility check functions perform a wide and diverse range of tests during data logging.
In this way warnings can be generated or default values substituted automatically for missing values, for example, or for values with invalid compressibility factors.
Even VN-VB or VB-VN plausibility checks are part and parcel of BelVis EDM GAS. The technical directions issued by the DVGW (German Technical and Scientific Association for Gas and Water) are also taken into account by standard plausibility checks. It is also possible to calculate compressibility k in accordance with SGERG-88. All the imported data are consulted for subsequent accounting or statement preparation.
Standard load profiles are allocated to the extraction points in the case of non-time-based consumers.
The load profile for non-time-based consumers is largely determined by the type of house construction and outside temperature. It therefore follows that these parameters run through the familiar stages in BelVis EDM GAS as well (normal daily consumption, daily consumption according to temperature) in order to yield standard load profiles for the interpolation of the annual consumption from daily and hourly rates. Standard load profiles (according to Munich Technical University) are then allocated to the extraction points. Needless to say, own daily and hourly coefficients are possible; the coefficients of the sigmoidal functions can also be adjusted simply.
Forecasts are the critical factors of operating success.
With BelVis EDM GAS:
forecasts can be generated based on the standard gas load profiles
reference prognoses can be calculated by specifying any reference time series
a load forecast can be generated for the day ahead on the basis of historic data and the relevant influencing variables, such as type of day and temperature, using the forecast wizard
any initial time series can be analyzed and short-range forecasts (week ahead) developed on the basis of the comparable day method
statistical functions (regression, load distribution and duration curves) effectively support the analysis of the historic data for influences, such as that of the air temperatures.
