For elite athletes, perfect ice is a hard requirement, and that requires flawless, uninterrupted operation of refrigeration compressors. When exploding controllers threatened continuity, HyTEPS engineers immediately identified the situation. With in-depth diagnosis, active filtering and continuous monitoring, we stabilised the electrical installation and structurally eliminated unplanned downtime.
At Thialf in Heerenveen, internationally renowned as the skating capital of the world, everything revolves around ice quality. Every day, the world’s top long-track speed skaters, short-track skaters and figure skaters train here. To keep the ice rinks at the perfect temperature under extreme loads, the heavy-duty cooling compressors must operate 24/7 without failure. For this elite sports facility, one simple rule applies: a cooling system failure is absolutely unacceptable.
Yet continuity was seriously compromised. Several years ago, a heavy-duty variable speed drive suddenly exploded in the electrical installation. At the time, this incident was still written off as a maintenance problem. However, when another regulator exploded two years ago, doubts struck. The component manufacturer took measurements and discovered a significant problem in the installation: an increased harmonic voltage distortion (THDu) of as much as 8%. This invisible contamination in the supply voltage was a ticking time bomb on the facility's operational reliability. Thialf sought an expert who could eliminate this uncertainty and guarantee a definitive solution.
To uncover the exact dynamics of the network, HyTEPS engineers performed Power Quality measurements on site, across the entire installation. This involved measuring for all Power Quality phenomena. Our analysis confirmed the previous findings: voltage harmonic distortion (THDu) structurally exceeded the 8% limit. Although AC drives themselves generate harmonic currents, the internal components are at the same time extremely vulnerable to a contaminated supply voltage. This interaction caused the destructive thermal overload in the compressors.
Leaving this grid contamination unchecked inevitably leads to accelerated equipment ageing and repeated failure. By accurately modelling the complex measurement data, we transformed an unpredictable problem into a concrete, manageable challenge. Based on the data obtained from our analysis, we designed an accurate solution. We modelled the filtering capacity required to eliminate overloads and optimise network efficiency. This proactive approach ensures that we are not symptomatic, but solve the problem at the source.
With the final design in hand, our engineers implemented two Active Harmonic Filters (AHF) within Thialf's installation. These systems monitor the network in real time and inject a counter current within milliseconds to immediately neutralise any detected contamination. As the cooling of the ice could not be interrupted for a moment, we tightly coordinated the commissioning with the technical department. As a result, the transition was seamless and the process went completely without safety risks.
The results from our validation measurements are convincing: the harmonic voltage distortion immediately dropped from a critical 8% to well below 4%. This guarantees that the power electronics again operate well within safe margins and are completely free of thermal overload. To ensure this optimal Power Quality permanently, we installed fixed meters and Thialf entered into a management contract. Our monitoring team now continuously monitors the installation data, allowing us to intervene proactively at the slightest deviation. Faults and overheated controllers are now a thing of the past.
