World Wind Day is celebrated on 15 June.
There are 20 national standards for renewable wind energy in our country.
Briefly about some of them.
GOST R 54418.23-2019, Renewable power engineering. Wind power engineering. Wind turbines. Part 23. Full-scale structural testing of rotor blades, first came into force on December 1, 2019.
The purpose of the blade test is to confirm that a particular type of blade, manufactured in accordance with certain requirements, is reliable and capable of withstanding loads throughout its service life.
The blade test plan shall include a product description, load specification, test conditions, and test equipment used in the test.
The manufacturer shall document the traceable data of the designed blade design. A unique blade identifier, supplier certificates and laboratory test reports for all used materials, weight and balancing report shall be provided.
If the blade is not damaged during the test, and its strength and test loads are correctly determined, the blade complies with the specified requirements.
GOST R 54418.14-2017, Renewable power engineering. Wind power engineering. Wind turbines. Part 14. Declaration of acoustic noise characteristics, first time came into force on July 1, 2018.
The document establishes the procedure for determining the sound power and sound pressure levels in the three-octave frequency bands, and sound tonality indicators for batches of equipment.
The range of wind speed values in which measurements are made and characteristics are set is determined by their type. Measurements shall be made over as wide a wind speed range as possible.
The minimum requirement is the determination of wind speed characteristics at the height of the wind wheel axis in the range from 0.8 m/s to 1.3 m/s of wind speed corresponding to a power level of 85 % of the maximum, rounded to the middle of the ranges.
GOST R 54418.2-2014, Renewable power engineering. Wind power engineering. Wind turbines. Part 2. Design requirements for small wind turbines, first time came into force on July 1, 2016.
The standard specifies the requirements for safety, quality control, reliability, as well as the requirements needed to ensure the technical safety of wind power plants with an area of less than 200 m2, converting the kinetic energy of wind into electricity.
In addition, the document contains requirements for design, installation, maintenance and operation of these products under normal and extreme environmental conditions.
Environmental factors affecting the integrity of the product design are taken into account during plant design. These include temperature fluctuations, humidity, air density, solar radiation, precipitation and seismic processes.
