From uncertainty to guaranteed performance

In today's energy transition, electrical installations are becoming more complex. The integration of power electronics, solar panels, charging stations and heat pumps creates dynamics that traditional 'hand calculations' can no longer predict. Many Technical Managers and Engineers struggle with the same questions: "What happens when I switch on this new production line?" or "Will my protection still be selective after the expansion?".

Gambling on a good outcome is not an option in electrical engineering. A faulty design leads to unnecessary downtime, dangerous situations and sky-high repair costs afterwards.

The power of prediction At HyTEPS, we believe in prevention. Our engineers use simulations not as a formality, but as a crucial design tool. Where a measurement tells you what is happening now, a simulation tells you what is going to happen. We map the invisible interactions between components - from harmonic distortion to dynamic load flows. This transforms uncertainty into hard data and technical validation. You only invest when you are sure the solution will work.

Digital Twin: your installation in a virtual environment

The basis of our approach is the Digital Twin. This is an exact, digital replica of your (future) electrical infrastructure. In this virtual environment, we can test infinitely without physical consequences.

Our specialists recreate your network in high-end software packages (such as Vision or DIgSILENT). In it, we enter all relevant parameters: from cable lengths and transformer specifications to the exact characteristics of your variable speed drives and generators.

Why a Digital Twin is indispensable:

  1. Scenario analysis: what happens during islanding? What if transformer A fails? We simulate N-1 scenarios and extreme loads.
  2. Validation of protection: We test whether protection devices trigger in time in the event of a short circuit, without bringing down the entire plant.
  3. Cost savings (CAPEX): Exact dimensioning prevents over-engineering. You buy exactly what is needed, no more and no less.
  4. First Time Right: Commissioning goes smoothly because teething problems are already solved in the simulation phase.

Our spectrum of simulations and calculations

We carry out a wide range of studies to ensure every aspect of your Power Quality and electrical safety.

Engineers view simulate harmonics

Simulating harmonics

Harmonic distortion (THD) is a growing problem due to the increase in non-linear loads such as LED lighting and variable speed drives. Too many harmonics lead to overheating of transformers, unexplained failures in sensitive equipment and a shortened lifetime of your assets.

In existing situations, we measure, but simulation is necessary in new construction or expansion. We predict the Total Harmonic Distortion (THDu and THDi) and test it against the limits (such as EN 50160 or IEEE 519). Does the simulation show that the limits are exceeded? Then we immediately design and validate the appropriate harmonic filter in the same model. This prevents you from having to apply expensive emergency measures afterwards.

Dynamic Loadflow simulations

A static calculation tells you whether a cable is thick enough for the average current. But your installation is not static. Motors start up(inrush currents), solar panels deliver peak power and business processes vary. With dynamic loadflow simulations, we look at the behaviour of your grid in the time domain. We analyse voltage dips when starting heavy motors, the load on transformers during peak production and the influence of day/night cycles. This is essential for optimising tap-settings on transformers and determining the right capacity for emergency power supplies (UPS/Generators).

Short circuit

Short-circuit current calculations

Huge mechanical and thermal forces are released during a short circuit. Can your distributors, busbar systems and cables withstand this? A short-circuit calculation is not only a regulatory requirement, but a fundamental safety check. We calculate the maximum and minimum short-circuit currents at each point in your installation. With this, we check whether your switchgear has sufficient breaking capacity (kA). If the short-circuit current exceeds the specification of your circuit breaker, it may explode instead of tripping. Our engineers identify these weak spots before things go wrong.

Arc Flash calculations

An electric arc is one of the most deadly phenomena in electrical engineering. For the safety of your staff (in accordance with NEN 3140 and NFPA 70E), you need to know how much energy is released during an internal shutdown.

Our arc simulations determine exactly the incident energy (cal/cm²) at the workplace. Based on this, we recommend the right Personal Protective Equipment (PPE) and, more importantly, measures to reduce the arc energy. Think about adjusting settings of protective relays, reducing the arc duration and minimising the impact. Safety is not a coincidence, it is a calculation.

Single line diagram

Resonance calculations

Resonance is every plant manager's nightmare. It occurs when capacitance (e.g. capacitor banks or long cables) and inductance (transformers) in your grid amplify each other at a specific frequency. The result: extremely high voltages that directly destroy components. Because resonance depends on changing grid configurations, this cannot be predicted by hand. Our software performs a frequency sweep to see where the resonance points are. We make sure your installation stays away from these dangerous frequencies, or design damping measures.

Grid compliance

Do you want to connect a solar farm, wind turbine or large battery system to the public grid? Grid operators are imposing increasingly strict requirements (Grid Codes, RfG). You need to prove in advance that your installation will not disturb grid quality. We carry out the required compliance studies. We simulate the impact of your inverters on harmonic distortion, voltage variations (flicker) and reactive power management. With our reports, you demonstrate compliance, preventing delays in grid connection.

Grid compliance
Simulations during expansions

Simulations during expansions

An expansion is never "just" an expansion. Adding a new production line or solar panels changes the impedance and load of your entire system. What was stable before can become unstable. We integrate your expansion plans into the simulation model of the existing situation. This allows you to see immediately whether the existing transformer can handle the extra load, whether the cables are not overloaded and whether Power Quality is maintained. We ensure that your growth does not become a risk.

Why investing in simulations pays off (CAPEX & OPEX)

Simulations are often seen as an additional cost at the beginning of a project. However, practice shows that it is one of the most profitable investments.

  • CAPEX Optimisation (Investment Cost): Without simulation, design is often based on rules of thumb and wide margins ("just take a size up just to be sure"). With a Digital Twin, we dimension exactly to size. You do not pay for redundant copper or oversized transformers.
  • OPEX Reduction (Operational Cost): A 'First Time Right' design means fewer failures, less wear and tear and lower energy bills (by reducing reactive current and losses).
  • Insurability and Compliance: Insurers increasingly demand demonstrable insight into risks such as electric arcs and fire hazards caused by harmonics. Our reports offer proof that you are "in control".

Frequently asked questions about measurements and analyses

Answer:

A Power Quality measurement analyses the current situation ("the patient is sick now"). A simulation predicts future behaviour ("if we do this, the patient will get sick"). Measurement is reactive or validating; simulation is proactive and preventive. We often use measurements as input to make the simulation model as realistic as possible.

Answer:

Yes, especially when complex components such as variable speed drives or PV systems are present. Even in smaller installations, resonance or overloading can lead to fire or failure. We adapt the scale of the simulation to the size of your installation.

Answer:

For a basic simulation, we need the Single Line Diagram and specifications of transformers, cables and large consumers. For detailed studies (such as harmonics), we also ask for data sheets of inverters and any measurement data of the current situation.

Answer:

Absolutely. We often perform a 'Design Review' or 'Second Opinion' on existing installer designs. We independently review the design for Power Quality and safety, so you can be sure that the completed work meets the requirements.

Answer:

Sure. This is even recommended. With a Load Flow or Harmonic simulation, we test your design in advance. This prevents you from having to adjust the installation after delivery.
