近年来,广东相继从国外引进了近200台具有80、90年代国际先进水平的大功率柴油机发电机组(单机组功率在4000kW以上),其中约50台(单机组标定功率为10240kW/500r/min)是从法国苏尔寿(SULZER)公司引进,建立了三十多个柴油机发电厂,大大缓和了电网供电不足的矛盾,对国民经济发展起到不可低估的作用.然而,柴电机工作时,产生强大的噪声,尤其是其进气口高达125dBA的啸叫声,在较大范围内对社会环境造成严重污染(距厂约50m处的居民点噪声高达80dBA).
In recent years, Guangdong has successively introduced nearly 200 high-power diesel generator sets with international advanced level from the 80’s and 90’s (the power of single unit is over 4000kW), of which about 50 sets (the rated power of single unit is 10240kW / 500r / min ) Was introduced from Sulzer (France) and set up more than 30 diesel power plants, which greatly eased the contradiction between the lack of power supply and the development of the national economy. However, during its work, Strong noise, especially the whistling sound of up to 125 dBA at the air intakes, caused serious pollution to the social environment (up to 80 dBA in settlements at a distance of about 50 m).
