Abstract

The invention provides a noise assessment and noise optimization method and device for an electric reactor. The noise assessment method for the electric reactor comprises the steps that basic parameter information of each coil in a to-be-measured electric reactor is acquired; according to the basic parameter information, the maximum displacement of each coil is calculated respectively; according to the maximum displacement and the basic parameter information, an effective value of the vibration velocity of each coil is calculated; according to the effective value of the vibration velocity of each coil, the noise level of the to-be-measured electric reactor is evaluated. The noise assessment and noise optimization method and device for the electric reactor have the advantages that the problem that the noise cannot be evaluated in the early design phase of the electric reactor, the assessment method is simple and effective, a basis is provided for performing noise optimization on the electric reactor subsequently, and the noise assessment and noise optimization method and device have guiding significance for noise reduction design of a smoothing reactor.

Description

technical field

[0001] The invention relates to the technical field of reactor noise reduction, in particular to a reactor noise evaluation and optimization method and device. Background technique

[0002] The dry-type smoothing reactor is connected in series between the converter valve and the DC line. It belongs to the equipment inside the converter station and is one of the most important equipment for high-voltage direct current transmission. It has the functions of limiting the sudden change of DC current, reducing the harmonic component, and smoothing the ripple of DC current. In addition to the DC part, the current flowing through each reactor also contains non-negligible high-order harmonic components, which become one of the main factors of noise sources in the converter station. Reactor noise has become a problem that cannot be ignored.

[0003] From the equipment point of view, noise reduction usually adopts two noise reduction measures, that is, noise reduction ...
