Simulation on expansion
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
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:
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.
