判断燃气发电机组是否已停机，可以通过以下几个步骤和指标来进行确认：

　　To determine whether the gas generator set has been shut down, the following steps and indicators can be used to confirm:

　　一、观察控制面板指示灯

　　1、 Observe the indicator lights on the control panel

　　检查故障指示灯：大多数发电机组在停机时会有相应的指示灯显示。例如，如果发电机组存在故障或未完成停机过程，故障指示灯可能会持续亮起或闪烁。因此，可以通过观察控制面板上的故障指示灯来判断发电机组是否已正常停机。

　　Check the fault indicator light: Most generator sets will have corresponding indicator lights displayed when they are shut down. For example, if the generator set has a malfunction or has not completed the shutdown process, the fault indicator light may continue to light up or flash. Therefore, it is possible to determine whether the generator set has stopped normally by observing the fault indicator light on the control panel.

　　注意停机指示灯：有些发电机组在停机后，停机指示灯会亮起或变为稳定状态，以指示发电机组已进入停机状态。

　　Pay attention to the shutdown indicator light: Some generator sets may turn on or stabilize after shutdown to indicate that the generator set has entered a shutdown state.

　　二、监听发电机组声音

　　2、 Monitor the sound of the generator set

　　在停机过程中，燃气发电机组的声音会逐渐减小，直至完全停止。因此，可以通过监听发电机组的声音来判断其是否已停机。如果发电机组的声音已经完全消失，且长时间内没有再次启动的迹象，那么可以初步判断发电机组已经停机。

　　During the shutdown process, the sound of the gas generator set will gradually decrease until it comes to a complete stop. Therefore, it is possible to determine whether the generator set has stopped by monitoring its sound. If the sound of the generator set has completely disappeared and there is no sign of restarting for a long time, it can be preliminarily judged that the generator set has stopped.

　　三、检查发电机组运行状态

　　3、 Check the operating status of the generator set

　　观察转速表：燃气发电机组的转速表可以显示发电机组的转速情况。在停机过程中，转速会逐渐降低至零。因此，可以通过观察转速表来判断发电机组是否已停机。如果转速表显示转速为零，且长时间内没有变化，那么可以认为发电机组已经停机。

　　Observing the tachometer: The tachometer of a gas generator set can display the speed of the generator set. During the shutdown process, the speed will gradually decrease to zero. Therefore, it is possible to determine whether the generator set has stopped by observing the tachometer. If the tachometer displays zero speed and there is no change for a long time, it can be considered that the generator set has stopped.

　　检查输出功率：在停机后，发电机组的输出功率会降至零。因此，可以通过检查输出功率来判断发电机组是否已停机。这通常需要通过专业的检测仪器或设备来完成。

　　Check output power: After shutdown, the output power of the generator set will drop to zero. Therefore, it is possible to determine whether the generator set has stopped by checking the output power. This usually requires the use of professional testing instruments or equipment to complete.

　　四、确认燃气供应已切断

　　4、 Confirm that the gas supply has been cut off

　　燃气发电机组在停机前需要切断燃气供应。因此，在判断发电机组是否已停机时，还需要确认燃气供应是否已经完全切断。这可以通过检查燃气阀门的状态来完成。如果燃气阀门已经关闭，且没有燃气泄漏的迹象，那么可以认为燃气供应已经切断，发电机组已经停机。

　　The gas generator set needs to cut off the gas supply before shutting down. Therefore, when determining whether the generator set has been shut down, it is also necessary to confirm whether the gas supply has been completely cut off. This can be accomplished by checking the status of the gas valve. If the gas valve has been closed and there is no sign of gas leakage, it can be considered that the gas supply has been cut off and the generator set has been shut down.

　　五、综合判断

　　5、 Comprehensive judgment

　　除了以上几个步骤外，还可以结合其他指标进行综合判断。例如：

　　In addition to the above steps, other indicators can also be combined for comprehensive judgment. For example:

　　检查发电机组的冷却系统是否已经停止运行；

　　Check if the cooling system of the generator set has stopped running;

　　观察发电机组是否有异常振动或噪音；

　　Observe whether there is any abnormal vibration or noise in the generator set;

　　确认发电机组是否已经与电网断开连接（如果适用）。

　　Confirm if the generator set has been disconnected from the grid (if applicable).

　　综上所述，判断燃气发电机组是否已停机需要综合考虑多个方面的因素。在实际操作中，应根据具体情况选择合适的判断方法和指标，并确保操作人员具备相应的专业知识和操作技能。

　　In summary, it is necessary to consider multiple factors comprehensively to determine whether the gas generator unit has been shut down. In practical operation, appropriate judgment methods and indicators should be selected according to the specific situation, and the operators should be ensured to have corresponding professional knowledge and operational skills.
