户外变电站噪声预测及优化控制设计

变电站噪声会对周边环境产生影响，针对如何降低其影响，开发了“变电站环境噪声仿真分析及优化控制系统”软件，然后通过对噪声源、建筑物、敏感点、树木以及其它障碍物的整体仿真分析计算，优化新建变电站的规划设计方案和运行变电站的噪声治理方案。该方法能够提高噪声控制效果，降低工程造价，避免噪声控制设计过程中的随意性和盲目性，具有一定的推广应用价值。

Noise Forecast and Optimal Control Design of Out-door Substation

In order to effectively reduce the effect of substation noise on surroundings and avoid blindness and randomness in the process of controlling it, a software called Substation ambient noise simulation analysis and optimal control system which based on basic theory of noise propagation is developed to realize optimal control analysis on substation noise. By contrast the actual measurement and simulation of the software ,demonstrated the effectiveness of the software and applied it to the actual substation projectnoise control project.On the one hand, in the process of planning and designing a new substation, find a optimal substation layout through calculating and analyzing noise sources (transformers and so on), buildings, sensitive points, trees and other obstacles to reduce the effect of substation noise on surroundings;On the other hand, in the process of noise abatement, put forward an noise barrier design scheme through optimizing the height and location of barrier and optimally analyze several schemes, to meet the standard of environmental protection requirement and reduce project cost. From the actual example analysis shows that the method in the substation noise control project has a good application value.
