燃氣發電機組停機前的必做事項主要包括以下幾個方面：

　　The necessary precautions before shutting down a gas generator set mainly include the following aspects:

　　一、卸去負荷與冷卻機組

　　1、 Remove the load and cooling unit

　　卸去負荷：在停機前，必須先卸去機組的全部負荷，確保機組處于空載狀態。這可以通過逐步關閉連接到發電機組的負載設備或逐漸減少負荷來實現，避免突然卸載導致的機組不穩定。

　　Unloading load: Before shutting down, all loads of the unit must be unloaded to ensure that the unit is in an unloaded state. This can be achieved by gradually shutting down the load devices connected to the generator set or gradually reducing the load to avoid unit instability caused by sudden unloading.

　　冷卻機組：在空載狀態下，讓機組繼續運行一段時間，以便機組得到充分冷卻。特別是對于配置增壓器的機組，當水溫、油溫降至適宜溫度（如60℃以下）時，還需再空載運行一段時間（如5分鐘），以確保增壓器進一步冷卻，防止結膠、結碳和漏油現象。

　　Cooling unit: Keep the unit running for a period of time under no-load condition to ensure sufficient cooling. Especially for units equipped with a turbocharger, when the water and oil temperatures drop to a suitable temperature (such as below 60 ℃), they need to run without load for a period of time (such as 5 minutes) to ensure further cooling of the turbocharger and prevent glue, carbon, and oil leakage.

　　二、檢查控制系統與參數

　　2、 Check the control system and parameters

　　檢查控制系統：在停機前，需要檢查燃氣發電機組的控制系統是否正常工作，確?？刂破辽系母黜椫甘緹麸@示正常，無異常報警信息。

　　Check the control system: Before shutting down, it is necessary to check whether the control system of the gas generator set is working properly, ensuring that all indicator lights on the control screen are displaying normally and there are no abnormal alarm messages.

　　觀察機組參數：觀察機組的水溫、油溫、油壓等參數，確保其在正常范圍內。如有異常，應及時處理。

　　Observe unit parameters: Observe the water temperature, oil temperature, oil pressure, and other parameters of the unit to ensure that they are within the normal range. If there are any abnormalities, they should be dealt with promptly.

　　三、準備停機操作

　　3、 Prepare for shutdown operation

　　通知相關人員：在停機前，應通知相關人員，確保他們了解停機時間和原因，以便做好相應的準備工作。

　　Notify relevant personnel: Prior to shutdown, relevant personnel should be notified to ensure they understand the downtime and reasons, in order to prepare accordingly.

　　準備停機工具：確保所需的停機工具（如停機按鈕、急停按鈕等）處于可用狀態。

　　Prepare shutdown tools: Ensure that the required shutdown tools (such as shutdown buttons, emergency stop buttons, etc.) are in a usable state.

　　四、執行停機程序

　　4、 Execute shutdown program

　　按下停機按鈕：在控制屏上按下停機按鈕，啟動機組的停機程序。在停機過程中，機組會自動切斷燃氣供應，并關閉相關閥門和開關。

　　Press the shutdown button: Press the shutdown button on the control screen to start the shutdown program of the unit. During the shutdown process, the unit will automatically cut off the gas supply and close the relevant valves and switches.

　　觀察機組狀態：在停機過程中，應密切觀察機組的運行狀態，確保機組能夠平穩地停機，無異常聲響和振動。

　　Observing the status of the unit: During the shutdown process, the operating status of the unit should be closely monitored to ensure that it can be shut down smoothly without any abnormal sounds or vibrations.

　　五、停機后的注意事項

　　5、 Precautions after shutdown

　　等待機組完全停止：等待機組完全停止后，關閉控制屏的電源，并切斷機組的總電源。

　　Wait for the unit to come to a complete stop: After the unit comes to a complete stop, turn off the power supply to the control panel and cut off the main power supply to the unit.

　　檢查機組狀態：在停機后，應檢查機組的狀態，確保機組無異?，F象。如有異常，應及時處理。

　　Check the status of the unit: After shutdown, the status of the unit should be checked to ensure that there are no abnormal phenomena. If there are any abnormalities, they should be dealt with promptly.

　　清理機組：對機組進行清理，清除機組表面的灰塵和雜物。同時，還需對機組的進風口和出風口進行清理，確保通風暢通。

　　Cleaning the unit: Clean the unit to remove dust and debris from its surface. At the same time, it is necessary to clean the air inlet and outlet of the unit to ensure smooth ventilation.

　　維護保養：定期對燃氣發電機組進行維護保養，檢查機組的各項性能指標是否正常。如發現問題，應及時處理，確保機組的正常運行。

　　Maintenance: Regularly maintain the gas generator set and check whether its various performance indicators are normal. If any problems are found, they should be dealt with in a timely manner to ensure the normal operation of the unit.

　　綜上所述，燃氣發電機組停機前的必做事項涉及負荷卸載、機組冷卻、控制系統檢查、參數觀察、停機準備、停機程序執行以及停機后的檢查與維護等多個方面。這些步驟的嚴格執行有助于確保機組的安全停機，延長機組的使用壽命，并提高發電效率。

　　In summary, the necessary tasks before shutting down a gas generator unit include load unloading, unit cooling, control system inspection, parameter observation, shutdown preparation, shutdown program execution, and post shutdown inspection and maintenance. The strict implementation of these steps helps ensure the safe shutdown of the unit, extend its service life, and improve power generation efficiency.
