摘　　要：将1台额定发电功率为2 kW的汽油发电机组改装成天然气发电机组。采用试验方法,对两种发电机组的转速稳定性、发电特性进行测试,比较两者的发电效率、污染物排放量、噪声、经济性。两种发电机组的转速稳定性、发电特性均满足要求。天然气发电机组的发电效率高于汽油发电机组,在污染物排放量、经济性方面优于汽油发电机组,但噪声略高。A gasoline generator set with rated output of 2 kW has been converted into natural gas generator set. The stability of rotation speed and power generation characteristics of two generator sets are tested by experimental methods to compare the power generation efficiency, pollutant emission, noise and economy of two generator sets. The stability of rotation speed and power generation characteristics of two generator sets all can meet demands. Natural gas generator set has an advantage over gasoline generator set in terms of power generation efficiency, pollutant emission and economic performance except for noise.
