燃气发电机组具有输出功率范围广，启动和运行可靠高、发电质量好、重量轻、体积小、维护简单、低频噪声小等优点，一般它们具有以下四个优点：
Gas generator units have the advantages of wide range of output power, high reliability of startup and operation, good power generation quality, light weight, small volume, simple maintenance, low low frequency noise, etc. Generally, they have the following four advantages:
一、发电质量好
1、 Good power generation quality
由于发电机组工作时只有旋转运动，电调反应速度快，工作特别平稳，发电机输出电压和频率的精度高，波动小，在突加空减50%和75%负载时，机组运行非常稳定，优于柴油发电机组的电气性能指标。
Because the generator set operates only in rotating motion, the electric regulation response speed is fast, the operation is particularly stable, the accuracy of the generator output voltage and frequency is high, and the fluctuation is small. When the load is suddenly increased by 50% and 75%, the operation of the generator set is very stable, which is superior to the electrical performance index of the diesel generator set.
二、启动性能好，启动成功率高
2、 Good startup performance and high startup success rate
从冷态启动成功后到满负载的时间仅为30秒钟，而规定柴油发电机启动成功后3分钟带负载。燃气轮发电机组可以任何环境温度和气候下保证启动的成功率。
The time from successful cold start to full load is only 30 seconds, while the international regulations stipulate that the diesel generator is loaded 3 minutes after successful start. The gas turbine generator set can guarantee the success rate of startup under any ambient temperature and climate.
三、噪声低振动小
3、 Low noise and vibration
由于燃汽轮机处于高速旋转状态，它的振动非常小，而且低频噪声优于柴油发电机组。
Because the gas turbine is rotating at high speed, its vibration is very small, and its low-frequency noise is better than that of diesel generator set.
四、采用的可燃性气体是清洁、廉价的能源
4、 The combustible gas used is clean and cheap energy
诸如：瓦斯气，桔杆气，沼气等，以它们为燃料的发电机组不仅运行可靠，成本低，而且能变废为宝，不会产生污染.

For example, gas, orange stem gas, biogas and so on. The generator set fueled by them is not only reliable in operation and low in cost, but also can turn waste into treasure without pollution
燃气发电机组由燃气发动机、发电机、控制柜等部件组成,燃气发动机与发电机安装在同一个钢制底盘上。机组以天然气、井口伴生气、煤矿瓦斯气、水煤气、炼化尾气、沼气、焦炉煤气、高炉煤气等可燃性气体为燃料,启动迅速,经济性好,特别是由于高质量城市生活的需求,燃气发电机组已广泛应用于电信、邮局、银行、图书馆、医院、宾馆等部门,作为后备电源。
The gas generator set consists of gas engine, generator, control cabinet and other components. The gas engine and generator are installed on the same steel chassis. The unit is fueled by combustible gases such as natural gas, wellhead associated gas, coal mine gas, water gas, refining tail gas, biogas, coke oven gas, blast furnace gas, etc. It is quick to start and has good economy. Especially due to the demand of high-quality urban life, the gas generator unit has been widely used in telecommunications, post offices, banks, libraries, hospitals, hotels and other departments as a backup power supply.
燃气发电机组是针对矿场工况设计的,机组运行时产生的噪声一般为95~110 dB(A)。GB 3096-93城市区域环境噪声标准对市区的噪声状况进行了严格的规定,对于2类区域(居住、商业、工业混杂区)昼间为60 dB(A),夜间为50dB(A);对于1类区域(居住、文教机关区)昼间为55 dB(A)、夜间为45 dB(A)。
The gas generator unit is designed for the mine conditions, and the noise generated by the unit during operation is generally 95~110 dB (A). GB 3096-93 Environmental Noise Standard for Urban Areas has strict regulations on the noise situation in urban areas. For Class 2 areas (residential, commercial and industrial mixed areas), the noise level is 60 dB (A) in the daytime and 50 dB (A) at night; 55 dB (A) in the daytime and 45 dB (A) at night for Class 1 areas (residential, cultural and educational institutions).
机组运行时产生的噪声给城市环境带来了严重的噪声污染,影响了人们的正常工作和生活,也限制了燃气发电机组的广泛应用。本文就是针对燃气发电机组噪声污染问题,提出了一套整改措施,以期降低机组噪声,促进燃气发电机组的推广应用。
The noise generated by the unit operation has brought serious noise pollution to the urban environment, affected people's normal work and life, and also restricted the wide application of gas generator units. This paper proposes a set of rectification measures to reduce the noise pollution of gas generating units and promote the popularization and application of gas generating units.
