Abstract

발전소의 실내는 규모가 크고, 위치마다 소음레벨 편차가 매우 크기 때문에 소음관리가 어렵다. 따라서 실내소음을 효과적으로 관리하기 위해서 소음분포를 분석할 수 있는 소음 가시화 시스템이 필요하다. 터빈실 내를 모델링하고, 선정된 지점의 소음레벨을 측정하여 소음지도를 작성할 수 있는 소음 매핑 시스템을 개발하였다. 그리고 모델의 신뢰성을 높이기 위하여 소음지도와 실제 소음측정 결과와 비교하는 방법을 통하여 모델을 수정하였다. 소음지도에 대한 정기적인 분석을 통하여 설비 이상을 판단할 수 있고, 특정 지점의 현재와 이전 소음에 대한 주파수 및 레벨을 비교 분석함으로써 실내소음을 효과적으로 관리하는 방법을 제시하였다. 매핑 시스템을 활용하면 근무환경을 개선할 수 있는 소음대책의 수립이 가능하고, 기계의 이상 유무를 확인하고, 예방정비를 통해 설비의 신뢰성을 높일 수 있다.

The noise management in the interior of the power plant is difficult because the interior is large and the noise level varies greatly from location to location. Therefore, a noise visualization system capable of analyzing the noise distribution is required in order to effectively manage the interior noise. A noise mapping system was developed that can model the inside of the turbine room and create a noise map by measuring the noise level at selected points. And in order to increase the reliability of the model, the model was modified through a method of comparing the noise map and the actual noise measurement results. Facility abnormalities can be determined through regular analysis of noise maps, and a method of effectively managing the interior noise is presented by comparing and analyzing the frequencies and levels of the current and previous noise at a specific point. By using the mapping system, it is possible to establish noise countermeasures that can improve the working environment, check the machine for abnormalities, and increase the reliability of the facility through preventive maintenance.
