AUDIBLE NOISE CALCULATION METHOD FOR HIGH VOLTAGE DC POWER TRANSMISSION LINE

摘要

An audible noise calculation method for a high voltage DC power transmission line, comprising three parts: (1) calculating the surface electric field intensity of a high voltage DC multiple conductor, (2) calculating an audible noise level of the high voltage DC line in summer, and (3) obtaining an audible noise level of other seasons by adding or subtracting a correction term. This method is simple and feasible, and can effectively solve the problem of predicting an audible noise of an ultra-high voltage DC power transmission line.
