Reliability via the realistic network simulation

What is a network simulation?

A simulation is a model reproduction of any real system or of a real process by means of a mathematical system.
With our network reproduction by means of PQ-Lib (Power Quality Library), one of our developed tools which has been tested for years, the existing network structure is so mathematically reproduced that the simulation results correspond to the real network with high accuracy (faults <1%). As a result complex networks and planned changes are presented so that the optimal solution for the customers regarding network restoration can be found. The measurement results of the network analysis can be integrated into the simulation as input variables. The results depicted in the simulation form the basis of the contract.

When should a network simulation be carried out?

A network simulation is always useful and necessary respectively if changes in the system configuration and/or changes of the consumer load structure are planned or take place as well as if the features of the network should be changed.
The simulation gives information about the network performance and the planned changes?
Additionally the behaviour of single components after an intended modification can be described in advance.

How is a network simulation carried out?

The simulation is carried out using the tools PQ-Lib in Modelica. These tools consist of individual elements which are mathematically described and are joined together as required to form complex modules. With these real networks (with very high precision) can then be mathematically reproduced. On the basis of the system configuration and line parameters, together with the results of the network analysis if necessary, the mathematical model of the system is developed. By means of changes in the individual parameters of the model all possible network status’ can be generated and their effect either presented or analysed. The presentation of the results is given in instantaneous values. Spectral analysis are also feasible.
