Summary This standard specifies the safety requirements for small wind turbine (SWT), quality assurance, engineering integrity and specific requirements for design, installation, maintenance and operational safety under specific external conditions. The aim is to provide an appropriate degree of protection during the life of the wind turbine to prevent damage to wind turbines at all risks. This standard covers all subsystems of small wind turbines, such as protective mechanisms, internal electrical systems, mechanical systems, support structures, bases, and electrical connections to loads. The small wind turbine (hereinafter referred to as the unit) includes a wind turbine itself including a support structure, a wind turbine controller, a charge controller / inverter (if required), cables and switches, installation and operation manuals and other documents.

1 Scope

This standard specifies the safety guidelines for small wind turbine (SWT), quality assurance, engineering integrity and under specific external conditions Specific requirements for the design, installation, maintenance and operation of safety. Its purpose is to provide adequate wind turbine life expectancy The degree of protection to prevent various dangers of wind turbine damage. This standard covers all subsystems of a small wind turbine such as protection mechanisms, internal electrical systems, mechanical systems, support structures, Basis and electrical connection to the load. Small wind turbine (hereinafter referred to as the unit) Including wind turbine itself containing the support structure, the wind Genset Controller, Charge Controller/Inverter (if required), Cables and Switches, Installation and Operation Manual, and other documentation. Although this standard is similar to IEC 61400-1, a simplified and equivalent amount of variation has been made to make it suitable for small wind turbines move. Several of the requirements of this standard can be modified if it is properly demonstrated that the safety of the wind turbine is not impaired. however, This rule does not apply to the definition of grading and related external conditions in Chapter 6. Adopting this standard does not mean any individual, organization or Groups can be exempt from the responsibility to comply with other appropriate procedures. This standard applies to the swept area of the rotor is not more than.200m2, the voltage is lower than the AC 1000V or 1500V DC grid Or off-grid wind turbine applications.
