特高压直流换流站噪声控制方案研究

讨论特高压换流站噪声治理，提出了一系列控制措施，包括：采用低噪声设备；采用Box-in型全封闭隔声罩的换流变压器；优化平面布置，如采用同极高低压阀厅面对面布置，交流滤波器集中布置，采用户内GIS等；对部分围墙采取控制措施，如提高围墙高度或者增加隔声屏障。采取上述措施后，敏感点和厂界测点全部达标，全站周围噪声分布令人满意。

Study on the Noise Control Scheme for UHVDC Converter Stations

The noise control of UHVDC converter station is discussed, and certain measures are proposed, including to use low-noise eqipments and en-closed boxing of converter transformers, to optimize the layout such as of face-to-face arrangment of the high-voltage and low-voltage valve halls of the same pole, centralized arrangment of the AC filter banks and indoor kind of GIS, and to control some parts of the bounding wall with the way to highten them or to build sound insulation screen on them. With these measures, the measurements of the test points are in agreement with the standards, and the noise distribution arounding station is satisfactory.
