CONFORMITY ASSESSMENT OF POWER PLANTS

Energy, fundamental in every part of our lives, is getting more and more importance with regard to its source. As SZUTEST, we offer product certification services based on our accreditation on EN ISO/IEC 17065 standard.

Energy, fundamental in every part of our lives, is getting more and more importance with regard to its source. A renewable source makes it sustainable at the same time. This trend towards renewable energy sources also takes up more space in our country every day. Conformity assessment of renewable energy sources is also very important as it is in all other sectors.

Pre-detection of potential non-conformities in equipment used in power plants makes it possible to fix problems that would cause high costs otherwise. Power plants represent a whole with advantages and risks. Our goal is to minimize these risks with the controls we carry out. All maintenance and repair work in power plants can be carried out under our supervision, and all risks are reported. Additionally, companies producing energy from renewable resources in our country are supported through the ‘Regulation on Certification and Support of Renewable Energy Sources’. We are also contributing to the support granted to national producers and playing an active role in this field.

Energy producers meeting the requirements of YEKDEM (Renewable Energy Resources Support Mechanism) can benefit from these incentives. One of these requirements is to hold a certificate of conformity issued by a conformity assessment body accredited on EN ISO/IEC 17065 standard. As SZUTEST, we are offering product certification service in this scope as well, based on the mentioned standard.

WIND TURBINES

SZUTEST, accredited by IAS (International Accreditation Service) on EN ISO/IEC 17065 Product Certification Standard, offers services of production surveillance and pre-installation inspections of wind turbines.

CERTIFICATION OF WIND TURBINES

Wind turbines operate on the simple principle that the energy in the wind turns two or three propeller-like blades around a rotor, and the rotor is connected to the main shaft, which spins a generator to create electricity.

Though their operation principle is the same, they differ in their components and the areas they are located.

There are 3 types of wind turbines in terms of their wing axes:

  • Horizontal axis wind turbines,
  • Vertical axis wind turbines,
  • Oblique axis wind turbines.

And there are 2 types according to location:

  • On land wind turbines, and
  • Offshore wind turbines.

It is also possible to classify wind turbines in terms of number of wings, wind direction or power.

The components of a wind turbine are blades, gear box, tower, generator and electronic parts.

According to their types, wind turbines are designed and manufactured based on the below standards:

  • EN 61400 – 1 Design requirements
  • EN 61400 – 2 Small wind turbines
  • EN 61499 – 3 Offshore wind turbines

The conformity assessment of tirbunes is carried out as a procedure where the requirements imposed by these standards are questioned. The conformity assessments and certification of wind turbines are performed based on EN 61400-22 standard.

The conformity assessment of wind turbines according to relevant standards is important not only because it is supported by YEKDEM but also because it prevents possible problems that may be experienced during the life span of the products.

SZUTEST, accredited by IAS (International Accreditation Service) on EN ISO/IEC 17065 Product Certification Standard, offers services of production surveillance and pre-installation inspections of wind turbines.

Electricity manufacturers can benefit from several incentives if the requirements imposed by the “Regulation on Subsidies to Electricity Manufacturing from Renewable Energy Resources for Using Domestic Components” are met. In order to be eligible for the incentive, manufacturers must apply to YEKDEM and present a certificate that shows that the equipment/components, listed in “Locally Manufactured Equipment/Components” given in Annex 1 of the regulation, comply with the relevant standards and requirements. SZUTEST offers this certification service as well.

HYDROELECTRIC POWER PLANTS

CERTIFICATION OF HYDROELECTRIC POWER PLANTS

Hydroelectric power plants are electricity generation facilities where the potential energy of the water at a certain altitude is transformed into mechanical energy and then to electrical energy with the principle of passing through the lower turbine wheels.

 

The water, which is at a higher level than the turbine, is directed to the turbines through channels where the electric energy is generated. The water is allowed to fall on the turbine blades that start rotating (the form of the contact of water on blades can vary according to the type of the turbine), and electricity is generated through the generators connected to the rotating blades.

The most commonly used HPP types are Kaplan, Francis and Pelton.

As already known, manufacturing of hydroelectric power plants consists of 3 basic stages:

  • Production of mechanical parts,
  • Hydrogenerator
  • Governor and software

TSE K 195 “Product Certification Guide for Turbines, Hydrogenerators and Governor Systems Used in Hydroelectric Power Plants” is the standard that defines the conformity assessment procedures covering these 3 stages.

Though this standard is essential, technical specifications and requirements of investers are also used in the conformity assessment process.

To benefit from the incentives the “Regulation on Subsidies to Electricity Manufacturing from Renewable Energy Resources for Using Domestic Components” should be carefully reviewed. As reinforced in the regulation, products must be certified by bodies accredited on EN ISO/IEC 17065 Product Certification Standard.
