DESIGN OF HVDC CONVERTER STATIONS WITH RESPECT TO AUDIBLE NOISE REQUIREMENTS

The purpose of this paper is to provide an overview of the engineering methods, tools, design solutions and verification methods used in the design of HVDC converter stations subject to acoustic requirements. T he sound generation part, item 3, describes how the sound power level radiated from electrical components can be calculated based on the loa d. The sound propagation part, item 4, describes how the sources are a ffecting the sound pressure level at immission points of interest. A m ethod to break down the acoustic requirement to component level and pr actical studies to verify the concordance with the requirements are al so illustrated. Different solutions for screening and absorption are d escribed as well as measurement methods. Items 5 to 8 describe a worki ng method used to fulfil outdoor acoustic requirements.
