摘　　要：大连柔性直流输电工程受端换流站地处大连市区中心,站界噪声需要控制在Ⅰ类标准。换流站的噪声源主要来源于户外设备,根据总平面布置方案采用Soundplan软件对站区进行模拟仿真,计算换流站采用水冷和空冷2种方案的噪声,当不满足噪声要求时,采用降噪措施使之降至45 d B以下。该工程因故没有实施,但是前期研究结果具有一定意义,有必要共同探讨。Convertor station of Dalian voltage source converter based on HVDC transmission system is located in central urban of Zhongshan district.Converter station noise should be controlled within standard Ⅰ.Noise source comes from outdoor devices.According to the general layout plan,a simulation using Soundplan is done to simulate and calculate noise levels of water cooling and air cooling.After implementing counter-noise measures,noise level is reduced to below 45 decibels.Although this engineering project is not actually realized,it is believed that the simulation results help to make sense in the future.
