Grid calculation: the basis of any power supply

All of us use electricity every day, but only a few of us think about electricity grids and the supply of electricity. This suddenly becomes relevant once you have an electro-technical system in place. Without a sophisticated power supply system, both the safe supply of electricity and general safety are at risk. The latter can be the case when a fire breaks out due to over-voltage, for example. A grid calculation is an essential part of every DriveCon project to make sure that the electricity flows as planned and all components are sufficiently dimensioned.

Existing systems:
determination of the current status

Within the scope of the network calculation, we update the simulations for your energy grid. Through an extensive inventory and precise analysis, we determine all the data required for the grid calculation for existing systems. We place great value on verifying the current status of the grid early on. This often allows us to discover weak spots, especially in existing electrical systems and grids.


For our engineers, this makes the grid calculation an important tool for verifying the feasibility of expanding the system. It also helps us to play through potential scenarios for different levels of grid utilisation and find the best possible solution for you. The data collected forms the basis for assessing the existing power grids and the investments required.

New systems:
planning the electrical engineering from the start

With the planning of a new technical system, we take over the planning of the electrical engineering from the original idea right up to final execution. Matching and calculating all the components needed for a reliable power supply is one of our strengths. In doing so, it goes without saying that we take the wishes of our customers into account and at their request plan the grid so that, for instance, sufficient capacity is available for later expansion.

and analyses

We use modern calculation programmes for performing the grid calculation. Amongst other things, we use them to perform a load flow analysis, calculate short-circuit currents, determine utilisation levels for components and verify selectivity on protective devices. Our technical staff interpret the results and make any suggestions required for necessary improvement measures. This results in a clear graphical representation of your entire grid structure and a grid calculation according to applicable DIN VDE regulations.
