Bachmann Monitoring, leading provider of turbine monitoring systems, develops a Condition Monitoring System (CMS) with extremely low electromagnetic interference emissions for a highly sensitive Dutch wind park.
“Do Not Disturb – Highly Sensitive Neighborhood”: Dutch wind park De Drentse Monden en Oostermoer (DMO) represented a real technical challenge for Bachmann. The Condition Monitoring System (CMS) had to maintain
electromagnetic interference emission levels significantly below the typical legal limit. In partnership with turbine manufacturer Nordex Group, whose N131/3900 turbine was built for particularly low interference emissions,
Nordex and Bachmann presented a convincing solution to clients Duurzame Energieproductie Exloermond BV, Raedthuys DDM B.V. and Wind Park Oostermoer Exploitatie B.V.
The “DMO” wind park, expected to have a total capacity of 171.6 MW, is located near the central antenna field of the “Low-Frequency Array” (LOFAR). This Europe-wide network containing thousands of highly sensitive radio antennas is used by the Netherlands Institute for Radio Astronomy ASTRON to research the universe. To avoid interference with the world’s largest antenna network, electromagnetic emissions from the wind park must be kept to a minimum. To achieve this, Nordex asked Bachmann to reduce the emissions of its CMS, normally operating in the range of 30 MHz to 240 MHz, to a level of at least 35 dB below the quasi-peak value.
