KLM's ambition to generate renewable energy on a large scale at Schiphol-East presents technical challenges. By installing 4 MW of PV panels on Hangar 14, KLM is opting for sustainability, but also for the need for impeccable Power Quality. Our engineers ensure that this green transition does not come at the expense of continuity at the airport.
At Amsterdam Airport Schiphol, downtime is not an option. While the airport and KLM realise their environmental goals by equipping Hangar 14 with 4 MW of solar panels, a technical tension arises. The inverters required for these renewable energy sources often introduce unwanted pollution into the power grid. This leads to uncertainty about the efficiency and safety of critical electrical installations and connected equipment.
Without proactive measures, these invisible Power Quality problems pose a direct risk to operational continuity. Production stops, accelerated component wear and unexplained failures lurk. KLM was therefore looking for a partner that would not only chart the status, but take full responsibility for a technically reliable solution.
To determine the exact impact of the 4 MW PV installation, we conducted an in-depth analysis. Our engineers placed Power Quality analysers at strategic locations near several transformers. Using continuous waveform recording, we mapped the full consumption profile, power capacity and load of the hangar. This method enables us to capture every detail of the electrical voltage and current, ensuring that no anomaly goes unnoticed.
Data analysis showed that one of the transformers was suffering from high odd harmonics. This contamination, together with observed spikes caused by switching loads, posed a direct risk to grid stability. By translating these results into a clear diagnosis, we gave KLM the necessary insight into Power Quality aspects such as Total Harmonic Distortion (THD). This approach forms the foundation for a targeted solution that removes uncertainty and extends the lifetime of the installation.
Based on our measurements, we recommended the installation of Active Harmonic Filters (AHF). These systems react at lightning speed to varying pollution and eliminate the harmonic currents caused by the solar panels. Our engineers seamlessly integrated these filters into Hangar 14's existing network, achieving an immediate reduction in grid pollution, which means the installation now complies with the strictest standards and guarantees operational reliability at Schiphol.
The result is a stable installation in which the negative effects of solar panels are completely neutralised. Besides eliminating interference risks, the Active Harmonic Filter reduces the absorption of reactive power. This increases the available capacity of the transformers and avoids unnecessary fines from the grid operator. In addition, we provided advice on reducing inrush currents and applying 'peak shaving', thereby maximising KLM's energy consumption efficiency.
Our approach at KLM proves that sustainability and reliable installation go hand in hand. By timely anticipating Power Quality risks, we prevent unplanned downtime and ensure the continuity of your critical processes. Want to know how we can optimise your installation?
