1 Scope This standard specifies essential design requirements 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. This standard is concerned with all subsystems of wind turbines such as control and protection mechanisms, internal electrical systems, mechanical systems and support structures. This standard applies to wind turbines of all sizes. For small wind turbines IEC 61400-2 may be applied. This standard should be used together with the appropriate IEC, ISO and Chinese standards mentioned in Chapter 2. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 4662-2003 Rolling Bearings - Static Load Ratings (ISO 76: 1987) GB 5226.3-2005 Safety of Machinery - Electrical Equipment of Machines - Part 11: Requirements for HV Equipment for Voltages Above 1,000V a.c. or 1,500V d.c. and Not Exceeding 36kV (IEC 60204-11: 2000) GB 16895.3- 2004 Electrical Installations of Buildings - Part 5-54: Selection and Erection of Electrical Equipment - Earthing Arrangements, Protective Conductors and Protective Bonding Conductors (IEC 60364-5-54: 2002) GB/T 17799.1-1999 Electromagnetic Compatibility - Generic Standards - Immunity for Residential, Commercial and Light-industrial environments (IEC 61000-6-1: 1997) GB 17799.2-2003 Electromagnetic compatibility - Generic standars - Immunity for industrial environments (IEC 61000-6-2: 1999) GB 17799.4-2001 Electromagnetic compatibility - Generic Standards - Emission standard for industrial environments (IEC 61000-6-4: 1997) GB/T 19001-2008 Quality management systems – Requirements (ISO 9001: 2008) GB/T 19271.1-2003 Protection against lightning electromagnetic impulse - Part 1: General principles (IEC 61312-1: 1995) GB/T 20320-2006 Measurement and assessment of Power quality characteristics of Wind turbine generator system (IEC 61400-21: 2001) IEC 60204-1: 1997 Safety of Machinery - Electrical Equipment of Machines - Part 1: General Requirements IEC 60364 (all parts) Electrical Installations of Buildings IEC 60721-2-1: 2002 Classification of Environmental Conditions - Part 2: Environmental Conditions Appearing in Nature - Temperature and Humidity IEC 61024-1: 1990 Protection of Structures against Lightning - Part 1: General Principles IEC 61400-24: 2002 Wind Turbine Generator Systems - Part 24: Lightning Protection ISO 281: 1990 Rolling Bearings - Dynamic Load Ratings and Rating Life ISO 2394: 1998 General Principles on Reliability for Structures ISO 2533: 1975 Standard Atmosphere ISO 4354: 2009 Wind Actions on Structures ISO 6336 (all parts) Calculation of Load Capacity of Spur and Helical Gears 3 Terminologies and Definitions For the purposes of this document, the following terminologies and definitions apply. 3.1 Annual average Mean value of a set of measured data of sufficient size and duration to serve as an estimate of the expected value of the quantity. The averaging time interval should be a whole number of years to average out non-stationary effects such as seasonality. 3.2 Annual average wind speed (Vave) Wind speed averaged according to the definition of annual average 3.3 Auto-reclosing cycle Event with a time period, varying from approximately 0.01 s to a few seconds, during which a breaker released after a grid fault is automatically reclosed and the line is reconnected to the network. 3.4 Blocking (wind turbines) Use of a mechanical pin or other device (other than the ordinary mechanical brake) that cannot be released accidentally to prevent movement, for instance of the rotor shaft or yaw mechanism. 3.5 Brake (wind turbines) Device capable of reducing the rotor speed or stopping rotation. Note: the brake may operate on, for example, aerodynamic, mechanical or electrical principles. 3.6 Characteristic value Value having a prescribed probability of not being attained (i.e. an exceedance probability of less than or equal to a prescribed amount). 3.7 Complex terrain Surrounding terrain that features significant variations in topography and terrain obstacles that may cause flow distortion. 3.8 Control functions (wind turbines) Functions of the control and protection system that based on information about the condition of the wind turbine and/or its environment, adjust the turbine in order to maintain it within its operating limits. 3.9 Cut-in wind speed (Vin) Lowest wind speed at hub height at which the wind turbine starts to produce power in the case of steady wind without turbulence.
