燃气发电机组的工作原理基于热力学能量转换与电磁感应原理的有机结合，其核心工作流程可分为燃烧做功与发电两个关键阶段：

　　The working principle of a gas-fired generator set is based on the organic combination of thermodynamic energy conversion and electromagnetic induction principles. Its core workflow can be divided into two key stages: combustion work and power generation:

　　在燃烧做功阶段，燃气发动机严格遵循四冲程内燃机的工作循环，通过精确控制燃气与空气的混合比例形成可燃混合气，经火花塞定时点火后，混合气在密闭气缸内发生剧烈燃烧反应，产生的高温高压燃气推动活塞做往复直线运动，再通过精密加工的连杆机构将直线运动转换为曲轴的旋转运动，从而高效地将燃气的化学能转化为机械能；

　　During the combustion stage, gas engines strictly follow the working cycle of a four stroke internal combustion engine. By precisely controlling the mixing ratio of gas and air, a combustible mixture is formed. After ignition by a spark plug, the mixture undergoes a violent combustion reaction in a closed cylinder, producing high-temperature and high-pressure gas that drives the piston to perform reciprocating linear motion. The linear motion is then converted into the rotational motion of the crankshaft through a precision machined connecting rod mechanism, thereby efficiently converting the chemical energy of the gas into mechanical energy;

　　在发电阶段，曲轴通过精密联轴器带动发电机转子在定子磁场中做高速旋转运动，根据法拉第电磁感应定律，定子绕组中会产生连续变化的感应电动势，经专业设计的电气系统整合后输出稳定的三相交流电，实现机械能向电能的高效转换。

　　During the power generation phase, the crankshaft drives the generator rotor to rotate at high speed in the stator magnetic field through a precision coupling. According to Faraday's law of electromagnetic induction, a continuously changing induced electromotive force is generated in the stator winding. After integration with a professionally designed electrical system, stable three-phase AC power is output, achieving efficient conversion of mechanical energy to electrical energy.

　　在使用方法方面，燃气发电机组的规范操作流程包括启动前准备、启动机组、运行维护和停机操作四个关键环节：

　　In terms of usage, the standardized operation process of gas generator sets includes four key steps: preparation before starting, starting the unit, operation and maintenance, and shutdown operation:

　　启动前必须对机组各系统进行全面的专业检查，包括但不限于确认燃气管道系统的密封性（工作压力需严格控制在0.05-0.3MPa的指定范围）、润滑系统的油质油量（按照制造商规定的500-1000小时更换周期执行）、冷却系统的防冻液配比（根据当地极端气候条件科学配置）以及电气系统的绝缘性能（绝缘电阻值不得低于0.5MΩ的专业标准）；

　　Before starting, a comprehensive professional inspection must be conducted on all systems of the unit, including but not limited to confirming the sealing of the gas pipeline system (the working pressure must be strictly controlled within the specified range of 0.05-0.3MPa), the oil quality and quantity of the lubrication system (according to the manufacturer's specified 500-1000 hour replacement cycle), the antifreeze ratio of the cooling system (scientifically configured according to local extreme weather conditions), and the insulation performance of the electrical system (the insulation resistance value must not be lower than the professional standard of 0.5M Ω);

　　启动过程中需严格按照操作规程依次开启燃气阀门、启动点火系统，并实时监控转速、电压、频率等关键参数（额定转速需稳定在1500r/min或3000r/min，电压波动控制在±5%以内，频率偏差不超过±2%）；

　　During the start-up process, it is necessary to strictly follow the operating procedures to sequentially open the gas valve, start the ignition system, and monitor key parameters such as speed, voltage, and frequency in real time (the rated speed should be stable at 1500r/min or 3000r/min, voltage fluctuations should be controlled within ± 5%, and frequency deviation should not exceed ± 2%);

　　运行期间应建立完善的巡检制度，通过分析排烟颜色、振动噪声等特征参数判断燃烧状况，同时详细记录各项运行数据以便进行趋势分析；停机操作必须遵循先卸载后断气的原则，待机组完全停止后还需进行系统的维护保养工作，包括清洁空气滤清器、检查紧固件状态等，确保设备始终处于最佳待机状态

　　During operation, a comprehensive inspection system should be established to determine the combustion status by analyzing characteristic parameters such as exhaust color, vibration noise, etc. At the same time, detailed records of various operating data should be kept for trend analysis; The shutdown operation must follow the principle of unloading first and then cutting off the gas. After the standby group is completely stopped, system maintenance work needs to be carried out, including cleaning the air filter, checking the status of fasteners, etc., to ensure that the equipment is always in the best standby state
