How to reduce the COE for Wind by fulfilling CE safety requirements

The EU Machinery Directive 2006/42/EC defines the safety and health protection of individuals with regard to risks in the use of machinery. If wind turbines are placed on the EU market, the CE conformity procedures must be carried out to comply with the Machinery Directive.

A key part of the Directive 2006/42/EC is that it is obligatory to the vendor of machine to carry out a risk analysis of the overall product, the wind turbine, with regard to the health of individuals.

The IEC 13849 is the harmonized safety standard for the Machinery Directive, and therefore has to be applied during the whole product life cycle of a wind turbine.

The GL 2010 is proposing so called “protection functions” for a wind turbine that can be interpreted as safety functions. For instant, the GL 2010 proposes a required Performance Level of PLr=d for moving the blades into the so called feathering position. But there is no standardized risk rating proposed within the standards today, and therefore the safety requirements for wind turbines are not well defined or even standardized which leads to non-safe technology on the one hand side or over designed high cost technology with low reliability due to high degree of complexity.

The wind industry is still very young compared to other industries and needs to come up to speed with industrial standards as soon as possible to:

1. 100 % comply with the machinery directive and its safety requirements for individuals

2. Improve the product development and life cycle processes to further increase product reliability which will lead to a reduction of the overall cost of energy for wind through higher availability in the field.

Join this webinar on 7th May to learn more about functional safety and how to apply its benefits to reduce the cost of energy for wind.

Presented by

Dr.-Ing. Tobias Rösmann,

Technology Development Manager - Wind

Dr.-Ing. Tobias Rösmann got his diploma in electrical engineering in 2006 from the TU Dortmund/Germany and then started with Moog as development engineer for Pitch Systems. In 2012 he obtained his Ph.D. degree in the field of electrical drive and motor control from the University of Wuppertal. Since then he's been leading the Department for Wind Technology Development at Moog.
