This standard is formulated for the first time.
The format and current rules of this standard are in accordance with the provisions of GR Jiang 1.12000 Standardization ". Work Guide Part 1: Structure and Compilation of Environmental Standards Delete 3,
Western Standards and Standards Jointly Proposed by the Machinery Industry Association. This standard is promoted by the Standardization Technical Committee of the whole painting wind for the view of sincerity. The former unit of this standard is: Inner Mongolia Tianfang Wind for Machinery!. The main drafters of this standard are: Xiao Zhanbei, Wen Yongjun, Zhong Yi: 1. Specification
Reliability requirements for off-grid wind turbine generator sets This standard defines the reliability requirements for off-grid wind turbine generator sets. JBT15395-2001
This standard is applicable to wind turbine generator sets with a swept area of ​​less than 4 under the wind turbine (hereinafter referred to as wind turbines) 2. Terms and definitions Definitions
The following terms and definitions apply to this standard. 21
Reliability
The ability of a unit to perform its specified functions under specified operating conditions and within a specified time. 2.2
ReliabilityThe probability that a unit will perform its specified functions under specified operating conditions and within a specified time. 2.3
Failure
Any component of a unit that fails to perform its specified functions or causes the change in performance to exceed a specified value under specified operating conditions is considered a failure.
Service life ife
refers to the time interval of unacceptable failure of a repairable product under specified conditions of use. 25
meantimeFirstTailurL refers to the average working time of a repairable product from the beginning of use to the occurrence of a failure. 2.6
meantimebetpeenfailures (MTDF)meantimebetpeenfailures is the average working time of a repairable product between corresponding failures. It is the basic indicator of reliability. 3. External conditions for unit operation
Analysis of the external environmental conditions for annual operation:
) In the case of a number of units, please refer to the manufacturer's The wind speed at high altitude is 1x-15m/s, and 4m/3 in high-cold areas:) The temperature range of the machine barrier is -20℃~+5℃, and the high zero area is -25453000m
center) The relative intensity is 95%:
e) In the atmosphere of the chemical light rack, in the northern region, the sand and dust conditions in the atmosphere are considered. 4 Correct operation and use conditions of the unit
The correct operation and use of the unit shall comply with the product manual. Or use in accordance with the provisions of the specification: social events and maintenance requirements are the premise, except for all external damage and irresistible natural factors. 5 The service life of each component of the unit
5 1 Wind rotor blades
JR:TG396—7004
The service life of wind rotor blades is divided into the following categories according to the manufacturing materials: a) Wood core glass fiber reinforced composite blades are 1 year b) Glass fiber reinforced plastic blades are 11 years 5.2 Other components
Other components are stored for 15 years.
