Drafting.
This document replaces GB/T 33629-2017 "Lightning protection for wind turbines". Compared with GB/T 33629-2017, except for the structure
In addition to adjustments and editorial changes, the main technical changes are as follows.
--- Added a review of lightning exposure assessment (see 7.1);
--- Changed the analysis of lightning strike frequency affecting a single or a group of wind turbines (see 7.2, 7.2 of the.2017 edition);
--- Changed the lightning protection requirements for blades (see 8.2.2, 8.2.2 of the.2017 edition);
--- Added requirements for bearing lightning strike test (see 8.4.2);
--- Change the informative Appendix D to a normative appendix (see Appendix D, Appendix D of the.2017 edition).
This document is equivalent to IEC 61400-24.2019 "Wind energy generation systems Part 24.Lightning protection".
The following minimal editorial changes were made to this document.
--- To coordinate with the existing standards, the document name is changed to. "Lightning Protection for Wind Power Generation Systems".
