The engine is coaxially connected with the generator and placed on the chassis of the whole machine. Then, the muffler and governor are connected to the engine. The gas source is connected to the gas channel in the engine, and connected to the recoil starter with pull rope on the engine and the voltage regulator connected to the output end of the generator. The combustible gas in the gas source is natural gas, liquefied petroleum gas or biogas. Compared with gasoline generator set and diesel generator set, the use of gas generator set can reduce the pollution to the environment, which is an environmental protection and energy-saving generator. Moreover, the structure is simple, the use is safe and reliable, and the output voltage and frequency are stable.

過濾裝置用於保護燃氣管路的閥門，過濾網的孔徑應不大於1.5MM。燃氣穩壓過濾裝置是燃氣輸配過程的主要和關鍵設備,主要承擔調壓和穩壓的功能,同時還要承擔過濾、計量、加臭、氣體分配等一項或多項功能。

The filter device is used to protect the valve of gas pipeline, and the aperture of filter screen shall not be greater than 1.5mm. Gas pressure stabilizing and filtering device is the main and key equipment in the process of gas transmission and distribution. It mainly undertakes the functions of pressure regulating and stabilizing, and also undertakes one or more functions such as filtering, metering, odorization, gas distribution, etc.

穩壓閥出口氣壓的波動在整個燃燒調節範圍內應不超過±5%。如氣閥列組配置獨立穩壓閥，其進氣口前端應配置獨立的過濾裝置，避免堵塞穩壓閥內的。

The fluctuation of pressure at the outlet of pressure stabilizing valve shall not exceed ± 5% in the whole combustion regulation range. If the air valve array is equipped with independent pressure stabilizing valve, the front end of the air inlet shall be equipped with independent filtering device to avoid blocking the pressure inside the pressure stabilizing valve.

The basic working principle and composition of the electronic control system of natural gas engine are analyzed, including air intake system and natural gas supply system. Based on GT power, the one-dimensional simulation average model of natural gas engine is established, including using neural network to train the relationship between relevant variables and calibrate the relevant loss. Then the relationship between natural gas engine and generator is analyzed On the basis of matching, the control strategy of gas generator set is studied, and the control strategy of electronic control system of natural gas engine is designed and simulated based on PID control and neural network control algorithm. The results show that the designed control strategy can better realize the speed control of natural gas engine and ensure the working stability of gas generator set.
