The invention discloses a general cap discharge voltage acquisition method. The method comprises the following steps of acquiring the diameter of a general cap to be tested; acquiring the initial discharge voltages of the general caps to be tested of the different diameters under different ground heights in a high altitude area; acquiring an altitude correction coefficient and the corrected discharge voltages of the general cap at different altitudes; fitting the acquired corrected discharge voltages, the altitude correction coefficient, the diameter of the general cap, and the ground height of the general cap to acquire the undetermined coefficient of a mathematical model; according to each parameter, establishing the mathematical model; and according to the mathematical model, acquiringthe discharge voltages to be tested of the general caps to be tested with the different diameters and the ground heights at the different altitudes. By using the general cap discharge voltage acquisition method, the discharge voltage of the general cap under the parameter can be obtained, and a reliable basis is provided for the diameter design of the general cap and ground height selection in engineering construction. The invention also discloses a general cap discharge voltage acquisition system.
Description
technical field [0001] The invention relates to the technical field of direct current transmission, in particular to a method and system for obtaining discharge voltage of a general cap. Background technique [0002] In the valve hall of the converter station, the general cap is one of the main fittings used. The selection of the diameter and height of the general cap in the valve hall of the converter station is directly related to the safe and stable operation of the DC project and the project investment. [0003] In the prior art, the main method for designing the diameter of the general cap in the valve hall of a high-altitude converter station and selecting the height of the general cap to the ground is the theoretical formula obtained after altitude correction of the empirical formula at low altitude. [0004] The inventor finds in the process of implementing the present invention that there are the following technical problems in the prior art: After the empirical fo...
