In the context of accelerating global energy structure adjustment and increasingly stringent environmental requirements, seeking efficient, clean, and reliable energy solutions has become a focus. As a power generation equipment that integrates advanced technology and environmental protection concepts, gas-fired generators are gradually emerging and playing an increasingly important role in the energy field. It uses combustible gases such as natural gas, biogas, and coalbed methane as fuel, and efficiently converts chemical energy into electrical energy through a series of precise mechanical and electrical conversion processes, providing stable power support for many fields such as industrial production, commercial operations, and residential life. ?

燃氣發電機組主要由燃氣發動機、發電機、控制系統以及輔助設備等部分構成。燃氣發動機是整個機組的核心動力源，其結構設計與傳統的燃油發動機有相似之處，但針對燃氣燃燒特性進行了專門優化。發動機的氣缸、活塞、連桿等部件經過特殊處理，以適應燃氣燃燒產生的高溫、高壓環境，確保發動機的高效穩定運行。例如，氣缸內壁采用特殊的耐磨涂層，提高其抗磨損能力，延長發動機使用壽命。?

Gas generator sets are mainly composed of gas engines, generators, control systems, and auxiliary equipment. The gas engine is the core power source of the entire unit, and its structural design is similar to traditional fuel engines, but has been specifically optimized for the combustion characteristics of gas. The cylinder, piston, connecting rod and other components of the engine are specially treated to adapt to the high temperature and high pressure environment generated by gas combustion, ensuring the efficient and stable operation of the engine. For example, the inner wall of the cylinder is coated with a special wear-resistant layer to improve its wear resistance and extend the service life of the engine. ?

發電機則與燃氣發動機通過聯軸器緊密相連，將發動機輸出的機械能轉化為電能。常見的發電機類型為同步發電機，它由定子和轉子兩大部分組成。定子繞組產生感應電動勢，轉子則通過直流勵磁產生磁場，在發動機的帶動下高速旋轉，使定子繞組不斷切割磁力線，從而產生交流電。?

The generator is closely connected to the gas engine through a coupling, converting the mechanical energy output by the engine into electrical energy. The common type of generator is synchronous generator, which consists of two main parts: stator and rotor. The stator winding generates induced electromotive force, while the rotor generates a magnetic field through DC excitation, which rotates at high speed under the drive of the engine, causing the stator winding to continuously cut magnetic field lines and generate alternating current. ?

控制系統猶如燃氣發電機組的 “大腦”，負責監測和調控機組的運行狀態。它通過各種傳感器實時采集發動機的轉速、溫度、壓力以及發電機的電壓、電流等關鍵參數，并根據預設的程序和邏輯對這些參數進行分析處理。一旦發現運行參數偏離正常范圍，控制系統會立即發出指令，調整發動機的燃油供給量、進氣量或發電機的勵磁電流等，以確保機組穩定運行。例如，當發動機溫度過高時，控制系統會自動增加冷卻風扇的轉速，加強散熱效果；當電網電壓出現波動時，控制系統會迅速調節發電機的勵磁電流，穩定輸出電壓。?

The control system is like the "brain" of a gas generator set, responsible for monitoring and regulating the operating status of the unit. It collects key parameters such as engine speed, temperature, pressure, and generator voltage and current in real time through various sensors, and analyzes and processes these parameters according to preset programs and logic. Once the operating parameters deviate from the normal range, the control system will immediately issue instructions to adjust the fuel supply, intake, or excitation current of the engine or generator to ensure stable operation of the unit. For example, when the engine temperature is too high, the control system will automatically increase the speed of the cooling fan to enhance the heat dissipation effect; When the voltage of the power grid fluctuates, the control system will quickly adjust the excitation current of the generator to stabilize the output voltage. ?

輔助設備包括燃氣供應系統、冷卻系統、潤滑系統、排氣系統等。燃氣供應系統負責將清潔的燃氣精確地輸送至發動機的燃燒室，其關鍵部件如燃氣調壓閥、過濾器等，能夠確保燃氣壓力穩定、雜質去除，為發動機的高效燃燒提供保障。冷卻系統通過循環冷卻液帶走發動機運行過程中產生的大量熱量，防止發動機因過熱而損壞，常見的冷卻方式有水冷和風冷兩種。

Auxiliary equipment includes gas supply system, cooling system, lubrication system, exhaust system, etc. The gas supply system is responsible for accurately delivering clean gas to the combustion chamber of the engine. Its key components such as gas pressure regulating valves, filters, etc. can ensure stable gas pressure, remove impurities, and provide guarantees for efficient combustion of the engine. The cooling system removes a large amount of heat generated during engine operation by circulating coolant, preventing engine damage due to overheating. Common cooling methods include water cooling and air cooling.
