特高压直流换流站可听噪声分析与控制

随着特高压电网的快速发展,特高压直流换流站的可听噪声危害成为急需解决的一个问题,其关系到居住在站区附近人群以及站内运行人员的身心健康和工作效率甚至电网安全。通过对特高压直流换流站内声功率较大的设备噪声的产生机理和传播特性进行分析,提出了相应的噪声控制措施,并应用于复龙特高压直流换流站,通过软件仿真计算,取得较好的效果。

Analysis and control of audible noise in UHVDC converter station

As the UHV grid develope rapidly,the audible noise in UHVDC converter station becomes a problem to be imperatively resolved,for it impact on the health and work of the people who live around the station and the operator in the station,even the safety of the grid.The noise generation mechanism and spread characteristics are analyzed in this paper,also,noise control measures are proposed to be used in Fulong UHVDC converter station as an example.It shows that the measures work well though the emulator calculation.
