Embodiment Construction
[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0051]The present invention proposes a method for calculating the synthetic electric field strength and ion current density under haze weather. The theoretical basis is that the calculation equation of the ion flow field of the high-voltage direct current transmission line considering the haze particles is as follows:
[0052]
[0053]
[0054] J=K h ρ e E. s (3)
[0055] In the formula, E s In order to consider the synthetic electric field intensity of haze, the unit is V / m; ρ e Is the ion space charge density, the unit is C / m 3 ; ρ f is the charge density of suspended droplets, in C / m 3 ; ρ p is the space charge density of suspended haze particles in C / m 3 ;K h is the ion mobility in haze weather, the unit is m 2 / Vs; J is the ion current density, the unit is A / m 2 . The synthetic fi...
