文摘

The noise problem of UHVDC coverter stations which is more severe than that of HV ones, gets more and more attention. UHVDC converter stations noises mainly caused by converter transformer, smoothing reactor and capacitors and reactors of AC filter sets. Noise control measures must be taken by proper site selection, optimum general layout, sound source reduction, fully enclosed box of converter transformers, using low noise AC filter reactor and installing light sound insulation and sound barrier on walls surrounding the AC filter, etc. The noise of a UHVDC Converter Station is predicted by using the software of SoundPlan. The results show that the noise level of all the test points meets the standards after taking above measures. Both environmental benefits and economic benefits are realized.
