National Bureau of Machinery Industry
Implementation on January 1, 2000
JB/T7879-1999
This standard is a revision of JB/T7879-95 "The rule for naming the product of wind energy conversion system". The main technical contents remain unchanged. This standard replaces JB/T7879--95 from the date of implementation. Only the original standard was edited during the revision. This standard was proposed and managed by the National Technical Committee for Standardization of Wind Turbines. Drafting unit of this standard: Hohhot Animal Husbandry Machinery Research Institute. Main drafters of this standard: Unselected.
This standard was first issued in February 1988 as GB8975--88, and the standard number was adjusted to JB/7879-95 in September 1996. bZxz.net

The rule for naming the product of wind energy conversion system 1 Scope
JB/T7879-1999
Replaces JB/T7879-95
This standard specifies the rules for naming wind turbine products consisting of wind machinery (hereinafter referred to as wind turbines) and supporting working machinery.
2 Wind turbine product model
2.1 The wind turbine product model indicates the type and specification of the wind turbine product. The category and main features of the wind turbine product are indicated by capital Chinese phonetic letters and Arabic numerals.
2.2 The product model of a wind turbine consists of the wind turbine code, the working machine category code, the wind turbine type code, the main parameters and the improvement number. The model is compiled in the following block diagram sequence.
口二口

Wind turbine type code
Working machine category code
Wind turbine code
2.2.1 The wind turbine code
is represented by the first letter "F" of the Chinese pinyin of the word "wind" (FENG). 2.2.2 The working machine category code
is represented by the first letter of the Chinese pinyin of the keyword in the working machine name. For example, the generator is represented by the letter "D" of the Chinese pinyin for "electricity" (DIAN); the water pump is represented by the letter "s" of the Chinese pinyin for "water" (SHUI); the heating machine is represented by the letter "R" of the Chinese pinyin for "heat" (RE); the breeding machine is represented by the letter "Y" of the Chinese pinyin for "raising" (YANG), etc. 2.2.3 The wind turbine type code
is represented by the first letter of the Chinese pinyin of the keyword in the wind turbine type name. For example, the vertical axis wind turbine is represented by the letter "C" of the Chinese pinyin for "vertical" (CHUI); the oblique axis wind turbine is represented by the letter "x" of the Chinese pinyin for "oblique" (XIE); the type code of the horizontal axis wind turbine is omitted.
2.2.4 The rotor diameter
is represented by Arabic numerals, which is the value of the rotor diameter in m. At most one digit is allowed after the decimal point. 2.2.5 Rated output
Approved by the State Bureau of Machinery Industry on August 6, 1999, implemented on January 1, 2000
JB/T7879-1999
Expressed in Arabic numerals. Wind turbine generator set: Expressed in the numerical value of rated output power with kW as the unit of measurement; Wind water pumping unit: Expressed in the form of axb, where a is the numerical value of rated water output with m\h as the unit of measurement, and b is the numerical value of rated water lift with m as the unit of measurement; The output of other types of working machinery is expressed in the main parameters of their rated output characteristics. A maximum of two digits are allowed after the decimal point.
2.2.6 Rated wind speed
Expressed in Arabic numerals, with m/s as the unit of measurement, with a maximum of one digit allowed after the decimal point. 2.2.7 Improvement serial number
Expressed in Chinese phonetic letters, the model of the improved product should be annotated with the improvement serial number A, B after the main parameters of the original model...·2.2.8 Example of wind turbine product model compilation
a) The model of a horizontal axis wind turbine with a rotor diameter of 7m, a rated output power of 4kW and a rated wind speed of 8m/s is as follows ：FD7-4/8
b) The model of the horizontal axis wind water-lifting unit with a rotor diameter of 4m, rated water output of 1.1m/h, rated water lifting head of 40m and rated wind speed of 8m/s is as follows:
FS-1.1×40/8
c) The model of the vertical axis wind turbine generator set with a rotor diameter of 6m, rated output power of 3kW and rated wind speed of 8m/s is as follows:FDC6-3/8
d) The improved model of the unit in example a) is as follows:FD7-4/8A
