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. Whilst the airport and KLM are achieving their environmental targets by fitting Hangar 14 with 4 MW of solar panels, this is creating a technical challenge. The inverters required for these renewable energy sources often introduce unwanted interference into the electricity grid. This leads to uncertainty regarding the efficiency and safety of critical electrical installations and the connected equipment.
Without proactive measures, these invisible power quality issues pose a direct risk to operational continuity. Production stoppages, accelerated wear and tear of components and unexplained faults are ever-present risks. KLM was therefore looking for a partner that would not only assess the current situation but also take full responsibility for delivering 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 respond instantly to fluctuating grid disturbances and eliminate the harmonic currents caused by the solar panels. Our engineers seamlessly integrated these filters into Hangar 14’s existing network. This enabled us to achieve an immediate reduction in grid distortion, ensuring that the installation now complies with the strictest standards and that operational reliability at Schiphol is guaranteed.
The result is a stable installation in which the negative effects of solar panels are completely neutralised. In addition to eliminating the risk of faults, the Active Harmonic Filter reduces reactive power consumption. This increases the available capacity of the transformers and prevents unnecessary penalties from the grid operator. Furthermore, we provided advice on reducing inrush currents and implementing ‘peak shaving’, enabling KLM to maximise the efficiency of its energy consumption.
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?
