                摘要：电晕噪声不同于的传统的电气设备噪声，其发声位置高、频带宽、声源分散，是 750 kV 变电站噪声控制
                的薄弱环节。该文以西北某 750 kV 变电站为例，使用紫外成像仪定位了 36 处主要电晕噪声点，基于噪声实测
                和全站声场仿真分析，研究了电晕噪声对变电站声环境的影响。针对主要电晕点的实际情况，提出了具体的电
                晕噪声防治措施。治理措施在该站 750 kV I 母第 6 间隔电晕噪声治理中获得实际应用，治理后 I 母线下噪声平
                均降低 1.1 dB(A)，邻近处厂界噪声平均降低 3.3 dB(A)，取得了较为明显的效果。

                 Abstract: Corona noise position is high and scattered, and its frequency bandwidth is wide. This makes it
                 different from the noise of traditional electrical equipment. This paper takes a 750 kV substation in Northwest
                 China as an example, 36 main corona noise points have been located using an ultraviolet imager. Based on the
                 noise measurement and the sound field simulation analysis of the whole station, the influence of corona noise is
                 studied. Specific measures to prevent and control corona noise are proposed for the main corona points. The
                 treatment measures have been practically applied in the substation. After treatment, the noise under bus I is
                 reduced by 1.1 dB(A) on average, and the noise in the vicinity of plant boundary is reduced by 3.3 dB(A) on
                 average.
