The invention discloses a method for researching the influence of a micro-
landform strong wind area on the safety operation of an electric
transmission line. The method for researching the influence of the micro-
landform strong wind area on the safety operation of the electric
transmission line comprises the steps that (1) a
stepwise regression equation a1 is established based on a strong wind factor set a1 and a
landform factor set a1; (2) the landform factor set a1 is substituted into the
stepwise regression equation a1, so that a
simulation strong wind factor set a1 is obtained; (3) based on the
linear relationship between the
simulation strong wind factor set a1 and a strong wind factor set a2, a unary
linear regression equation a2 is established; (4) a landform factor set b1 is substituted into the unary
linear regression a2 so that a
simulation strong wind factor set b1 is obtained; (5) according to the difference
value set between the simulation strong wind factor set b1 and a strong wind factor set b2, a strong wind factor set b3 is obtained; (6) based on the strong wind factor set b3 and a landform factor set b2, a
stepwise regression equation b2 is established; (7) a modeling result is obtained, wherein the stepwise regression equation b2 and the unary
linear regression equation a2 are back substituted into the stepwise regression equation a1, and then the final modeling result is obtained.
