Protection Technology
Protection technology is one of the most important planning tasks for power supply networks. The aim of protection technology is to detect errors and to switch them off quickly and selectively. On the one hand, this protects the system from thermal and mechanical loads and, on the other hand, the faulty line is switched off in a targeted manner. With the increasing penetration of DEA into the power grid, the operating behavior of the grid changes and represents a challenge for protection technology.
From the point of view of protection technology, each project is unique due to the different customer requirements and the different technical feasibility. As part of network protection planning, individual solutions are developed that meet the technical requirements and customer requirements.
The basis of the protection technology is the network calculation (short circuit and load flow calculation). An evaluation of the existing protection parameters is carried out on the basis of the network calculation and the existing protection settings. Measures for optimal protection coordination are then recommended. If necessary, a new protection concept will be developed.
For new networks or network expansions, a protection concept with the selection of the appropriate protective devices must be developed. As part of the drafting of the protection concept, the appropriate protection devices (protection devices, converters, fuses) are selected and the required protection functions are determined according to the ANSI code. Protection parameters are then recommended.
We calculate the protection parameters for devices from all manufacturers (Siemens, ABB, Schneider, AEG, Alstom, Sprecher)

Transformer dimensioning
The stationary and transient transmission behavior of the current transformers are crucial to ensure reliable and safe protection technology. Especially for differential protection devices and busbar protection devices, a saturation-free current transmission of the transformer is important for proper functioning of the protection devices. When dimensioning the transformer, the protective cores of the current transformers are checked, taking into account the requirements of the protective devices, and measures are recommended if necessary.

Network planning
The power supply networks are experiencing a dynamic change. The reasons for this change are the technical and economic requirements as well as the political aspirations. A safe and reliable power supply is of the utmost importance for economic success.
In addition, politicians should act in an environmentally conscious manner through decarbonisation measures and strive for a sustainable power supply. This results in a steady increase in renewable energy sources and the integration of new players such as electromobility, storage technology and power to gas (p2G).
This brings with it new challenges. New tasks are added to the classic network planning tasks. Targeted and flexible network planning is required so that the networks can react successfully to dynamic changes in the electricity network.

network planning
Modeling the network in the network calculation program
The network is recorded in the network calculation program on the basis of network data. This is done schematically and / or similarly according to the customer’s request. The network data are checked for plausibility. The network modeling is the basis for the implementation of further network planning tasks. For successful planning, the digitized network should reflect the physical network as much as possible. The network is recorded in close cooperation with the customer.
