基于Cadna/A软件的特高压变电站噪声影响研究

摘要

The impacts of ultra-high voltage (UHV) substation on the surrounding environment are becoming increasingly apparent.It also has become an environmental problem to be solved urgently.Therefore, it is necessary to take measures to reduce noise impact on the outside acoustic environment in the phase of project design.The current and future boundary noise of a planned 1 000 kV UHV substation are predicted and analyzed with Cadna/A.Reasonable measures for noise control are also provided.It could provide evidence for the feasibility of construction projects and technical support for environmental impact assessment.%特高压变电站噪声对周围环境的影响愈发明显,已成为亟待解决的环境问题.这就必然需要提高变电站噪声控制标准,优化变电站噪声控制设计.基于Cadna/A噪声预测软件对某规划的1 000 kV特高压变电站本期及远期站界噪声进行预测分析,并提出合理的噪声治理措施,为建设项目的可行性提供依据和环境影响评价提供技术支持.
