LED system solution cuts an impressive figure in pilot installations

FieldPower® Wind Energy offers everything required for the interior lighting and supply of wind power installations. As a customised solution, the system is an integral component of the current tower installations of leading turbine manufacturers – such as Nordex, for example.

 

A job well done: the last of the 50 LED lights is installed! Twelve platforms and the wall areas are fitted with lights, and 200 metres of 2.5 mm² cable is connected up – ready to feed in 120 V DC and distribute it along the 120 metre route to the nacelle.

When the power is switched on, it’s the moment everyone has been waiting for: will the lighting meet the expectations of Nordex, the turbine manufacturer? Just a short time ago, this was a busy construction site, but now the switch is flipped and the single and dual LEDs come on at full output. The project team nod their heads with satisfaction. For Hans Schlingmann of Weidmüller, the driving force behind the FieldPower® Wind Energy system solution, this is a wonderful moment every time.

System configuration that meets requirements in full

“Our goal is not just to provide individual components, but to develop solution concepts that simplify work processes and enhance plant efficiency,” emphasises Mr Schlingmann, Business Development Manager Wind. “Successful pilot installations at customers such as Nordex demonstrate how that’s exactly what we do with our lighting and supply system for wind power installations.”

The core element of the solution is LED lights, which are notable for their low power consumption and low level of sensitivity to vibrations, shocks and extreme temperatures. These durable lights have proven themselves to be particularly robust during the installation process and are significantly less likely to fail. Together with a comprehensive system for an uninterruptible power supply as well as optional remote monitoring and outlets, they constitute a ready-to-fit solution for lighting, emergency lighting and power supply in the entire wind power installation. All parts have been tried-and-tested and are perfectly coordinated to one another. With comprehensive project support from Weidmüller, the system can be implemented with ease, whatever the application.

Knowing the benefits right from the outset

For the wind power installations that Nordex recently constructed near the district of Rostock, the project to install lighting in the towers began with

the collection of project data. “The installation size and type, location, environmental conditions, country-specific standards and legislation – all these factors affect the customised planning process for a plant,” explains Olaf Prein, Global Segment Manager Wind at Weidmüller. “In a CAD simulation that is accurate in every detail, we show our customers how our system can be integrated in their wind power installations and outline the concrete benefits. Having ascertained all the components required, we then

with the application-specific planning and implementation process for an individual supply and illumination concept.”

Weidmüller has lights to suit every requirement, which is a key advantage because Nordex plants are used all over the world, from Alaska to Australia. Unlike conventional lights, the Weidmüller LED solution is fully geared towards universal use under harsh environmental conditions. A suitable light type that constantly meets the same high technical requirements can be selected for all system versions.

“A thoroughly illuminating project”

“When a wind power installation is constructed and commissioned, all consumers are supplied by a single electricity generator. In the past, I have often experienced the scenario where, during construction, some consumers of the wind turbine draw so much power that it caused voltage fluctuations in the lighting circuit. As a result, we were left standing in the dark during the commissioning process and had to replace defective linear fluorescent luminaires again,” recalls Ralf Harder of Nordex. “It makes me all the more impressed by the LED system solution offered by Weidmüller. These impact-resistant lights proved their worth even when the wind power installation was being built. From the identification of requirements through to commissioning, the whole project has been thoroughly illuminating.”
