Simulation for extensions

Contemporary electrical installations are complex and as a result cannot always be easily overseen. Definitely not in the case of an expansion. Generally, it can’t be known whether the current installation might be affected by the extension. What used to be a robust installation can now easily become a failure-sensitive installation.

The benefits of simulation

  • Preventing problems and minimizing risk.
  • More efficient use of resources in production and construction of the installation.
  • Future-proof.
  • Cost effective.

Simulating the influence of solar panels on the electrical installation


PV installations have a large impact on the Power Quality and energy management of electrical installations. Where do you connect the PV? What is the effect of PV on the voltage and the harmonic distortion? These are large questions that can easily be answered by means of simulations. This guarantees the safety, continuous operation and lifespan of the installation.

Simulation options

By simulating the entire installation, bottlenecks and dangerous situations can be prevented under all circumstances. For example, the selectivity of the installation in stand-alone operation or the short-circuit current in the event of a defect can be analysed and recorded. Simulation increases insight in complicated installations in complex situations. It is also possible to combine scenarios, which would be practically impossible without simulations.

Building real estate and machinery for the future is about vision and prediction. We can identify the following trends:

  • Scarcity of capacity in the grid
  • The influence of e-mobility
  • The influence of storage and decentralized generation on your installation
  • The implementation of new grid connections
  • The effect of implementing cos phi compensation on the installation
  • Future developments of electrification in (heavy) industry

Sometimes an extension can be done ‘smarter’. Often, this soon becomes clear during simulation. An example of this is excessive reactive current in (parts of) the installation. Power that has a direct effect on the efficiency of the installation and can increase the energy bill. These currents can be efficiently compensated with a capacitor bank. This might even mean that a larger transformer won’t be required, or parts of the installation could still be constructed with a lower capacity. It is also possible to simulate Dynamic Load Flow, for example the switching on of a machine. This provides insight into possible voltage dips.

A cost-effective analysis can also be done on, for example, scheduled installation of an additional machine. Discussing the simulation results with your other suppliers can therefore certainly pay off.
Future decentralized generation and storage will have a major affect on the Load Flow and required capacity of the installation. This can also be taken into account at an early stage with simulations.

Simulate for safety assurance

Simulating your installation contributes to operational safety: risks are identified, for example by short-circuit calculations and arc flash calculations. This can prevent dangerous situations and provide insight into the risks when these situations are inevitable.

Prevention of Power Quality problems is better than cure

Power Quality phenomena are also simulated. This gives a good indication of problems that may arise. Examples are harmonic Load Flow and resonance calculations.

HyTEPS is an expert in simulating your installation


Simulating a future expansion is a cost effective way to mitigate risk and optimize existing and future resources. HyTEPS can support you in this area. Construction simulation provides the basis for gaining rapid insight into problems throughout the building lifecycle. This reduces the total cost of ownership.
