Wind Turbine Certification

Type and Component Certification Services for Manufacturers of Wind Turbines

DakkS Accreditation for Wind Turbine Certification according to IEC 61400

With the steadily growing number of manufacturers in the global market for wind energy, certification of wind turbines and wind turbine components is highly in demand and requires technical state-of-the-art skills. Certification according to harmonized standards and requirements boosts the export potential of products and so it is important for manufacturers to apply for the various types of certification available.

Our certification services for wind turbines and wind turbine components are based on the international standard IEC 61400 series. Our Certification Body for products is accredited by the German Accreditation Body according to EN 45011 for the certification of wind turbines according to the IEC 61400-series (see annex of the accreditation certificate at www.dakks.de ). In addition, we can ensure compliance with national standards and regulations, such as the DIBt and GL guidelines.

Our Approach to Wind Turbine Certification

Certification of wind turbines according to the international standard IEC 61400 series includes type certification and component certification.

Wind Turbine Type Certification

The purpose of type certification is to confirm that the wind turbine type is designed, documented, and manufactured to conform to the design specifications, specific standards and other technical requirements.

Demonstration is required that it is possible to install, operate and maintain the turbines in accordance with the design documentation. Type certification applies to a series of wind turbines of common design and manufacture; it contains procedures related to the design, manufacture, conformity testing, and to the plans for transportation, erection, installation, and maintenance.

Wind turbine type certification consists of the mandatory modules:

  • Design basis evaluation
  • Wind turbine design evaluation
  • Type testing
  • Manufacturing evaluation
  • Final evaluation

And the optional modules:

  • Foundation design evaluation
  • Foundation manufacturing evaluation
  • Type characteristic measurements

When type certification testing has been successful performed a wind turbine type certificate is issued, confirming the accordance of the wind turbine with design specifications, applicable standards and other technical requirements.

Wind Turbine Component Certification

Wind turbine component certification confirms that a major component of a specific type has been designed, documented, and manufactured to conform to the design assumptions, specific standards and other technical requirements.

The procedures for component certification are largely in line with the type certification procedures. The specific content of a module depends on the actual component.

Wind turbine component certification consists of the following modules:

  • Design basis evaluation
  • Design evaluation
  • Type testing
  • Manufacturing evaluation
  • Final evaluation

A component certificate usually covers a major wind turbine component, such as a blade or gearbox.

The International IEC 61400 Standard

The IEC 61400 standard issued first in 2001 by the International Electrotechnical Commission (IEC) is a set of design requirements and considerations aiming to ensure the engineering integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime.

The IEC 61400 series is concerned with all subsystems of wind turbines such as control and protection mechanisms, internal electrical systems, mechanical systems and support structures covering the following topics:

  • Design requirements
  • Design requirements for small wind turbines
  • Acoustic noise measurement techniques
  • Wind turbine power performance testing
  • Measurement of mechanical loads
  • Declaration of apparent sound power level and tonality values
  • Measurement and assessment of power quality characteristics of grid connected wind turbines
  • Full-scale structural testing of rotor blades
  • Lightning protection

The IEC 61400 standard applies to wind turbines of all sizes. For small wind turbines (PDF, 762 KB) IEC 61400-2 may be applied. The standard is used together with other appropriate IEC and ISO standards.

Wind Turbine Certification According to National Standards and Guidelines

In some countries, in addition to the international standard IEC 61400, special national guidelines and standards need to be considered for wind turbine certification.

Type Certification According to DIBt

In Germany there is an official type certification of towers and foundations according to the Center of Competence in Civil Engineering (Deutsches Institut für Bautechnik, DIBt). This certification is only to be carried out by a Notified Body, to ensure accordance with national regulations.

We can support you in all your needs with various wind turbine certifications to ensure the safety and compliance of your wind turbines.
