Protection of cable against short-term overheating.Protection against hazardous voltage (people protection), influence switch off in tolerable time.Tolerable voltage drop and voltage limits.Service current of consumer, influence current rating of cable.Maximum length of selected cable type and section for which the criteria is still fulfilled.

Sizing of one cable or any number of cables together (distributed radial network).

Device is taken from NEPLAN protection library

Automatic selection of protection device rating and setting.

The module can also be used for the inspection of already installed cables. However, it is important to consider the geographical conditions and then select an appropriate standard. The basic principle underlying cable sizing calculations remains the same for all these standards. The cable type can be selected either from the predefined cable library within NEPLAN or from user-defined cable libraries depending on various international standards such as VDE, IEC, NEC, etc. This module is used for the selection of the type and cross-sectional area of a cable as well as the protection device for an assumed passive or motor load and a given infeed.

Time simulation with load allocation could be found here.

Time simulation with field measurements could be found here.Time simulation with synthetic profiles could be found here.Statistical values visible in the single line diagram.Storage of minima and maxima as operating conditions.Histograms for voltages and element loadings.Violated limits are reported (maximum values and time percentage).In case synthtic load or generation profiles are used, the loads and generations are scaled according to the profiles defined for a Day, a Weak or Season and for a Long Term behaviour (see Scaling Types section). The result is again time dependent quantities, which are evaluated using statistical methods. Based on the normal load flow calculation, time ranges from minutes to years can be simulated. The module Load Flow Time Simulation uses measured time series as well as synthetic load or generation profiles. NEPLAN | Loadflow Time Simulation back to overview
