　　(1) After the generator set is running normally, first adjust the voltage and frequency of the generator set to be roughly the same as the power grid, then place the synchronous measurement switch in the "well car" position and observe the synchronous meter;

　　(2)、調整控制屏上的轉速微調電位器，使之與電網頻率相同，即同步表頻率差指示“Hz”指針處在中間略高位置:

　　(2) Adjust the speed adjustment potentiometer on the control screen to be the same as the grid frequency, that is, the synchronous meter frequency difference indicator "Hz" pointer is slightly higher in the middle:

　　(3) 、調節電壓整定電位器，使機組電壓與電網電壓相同，即同步表電壓差指示“V”指在中間位置。注意:反復調整發電機組，并觀察同步表相位差指示“S”指針，使其緩慢順時針旋轉。當指針旋轉接近垂直向上位置時，左手按下主開關合閘按鈕，右手斷開同步測量開關，主開關合閘并網發電。左手調整電壓整定電位器，將功率因數控制在滯后0.9-0.8之間，右手緩慢調整轉速微調電位器給機組加載。調整功率到合適位置(新機為60%Pe)最后將功率因數調整在0.8-0.9之間。

　　(3) Adjust the voltage setting potentiometer to ensure that the unit voltage is the same as the grid voltage, i.e. the synchronous meter voltage difference indicator "V" is in the middle position. Attention: Adjust the generator set repeatedly and observe the phase difference indicator "S" pointer on the synchronous meter to make it slowly rotate clockwise. When the pointer rotates close to the vertical upward position, press the main switch closing button with your left hand, disconnect the synchronous measurement switch with your right hand, and close the main switch for grid connected power generation. Adjust the voltage setting potentiometer with your left hand to control the power factor between 0.9-0.8 hysteresis, and slowly adjust the speed adjustment potentiometer with your right hand to load the unit. Adjust the power to the appropriate position (60% Se for the new machine) and finally adjust the power factor between 0.8-0.9.

　　(4)發電機并網運行中，應注意觀察電器儀表及微機柜主控畫面各項參數的指示狀況，并根據技術要求，及時修正各項參數。

　　(4) During the grid connected operation of the generator, attention should be paid to observing the indication status of various parameters on the electrical instruments and micro cabinet main control screen, and timely correcting various parameters according to technical requirements.

　　(5)機組正常運行中，每15分鐘作一次巡回檢查，觀察油溫、水溫、機油壓力、壓差、燃氣壓力及水位、油位，每兩小時對機組參數作一次記錄。三、發電機組的停機1、機組停機前，要先卸去負荷，緩慢逆時針調節轉速微調電位器，逐漸卸下負載。同時，緩慢旋轉電壓整定電位器，將功率因數控制在0.95-0.7之間，當功率降至50KW以下時，迅速按下分閘按鈕，然后使機組在額定轉速下運行幾分鐘。

　　(5) During normal operation of the unit, a patrol inspection is conducted every 15 minutes to observe the oil temperature, water temperature, oil pressure, pressure difference, gas pressure, water level, and oil level. The unit parameters are recorded every two hours. 3、 Shutdown of Generator Set 1. Before shutting down the generator set, the load should be removed first, and the speed adjustment potentiometer should be slowly adjusted counterclockwise to gradually remove the load. At the same time, slowly rotate the voltage setting potentiometer to control the power factor between 0.95-0.7. When the power drops below 50KW, quickly press the disconnect button and let the unit run at rated speed for a few minutes.

　　2、將轉速轉換開關撥至“怠速”位置，使機組轉速降至總速運行。

　　2. Turn the speed conversion switch to the "idle" position to reduce the unit speed to the total speed for operation.

　　3、待機組油溫、水溫降至40C以下時，關斷機組氣源蝶閥，將電磁閥開關、電調開關置于斷開位置，并按下微機柜緊急停機按鈕，機組停止。

　　3. When the oil and water temperature of the standby unit drops below 40C, turn off the air source butterfly valve of the unit, place the solenoid valve switch and electric control switch in the off position, and press the emergency stop button of the micro cabinet to stop the unit.

　　4、較長時間停機或機組檢修時，應關閉外循環冷卻水進口閥門和燃氣進口閥門。若環境溫度低于5C時，還應將機組內循環冷卻水放凈，并將水泵及外循環冷卻水管線上的放水堵打開將水放凈，必要時應用空氣壓縮機吹掃管線。

　　4. When the unit is shut down for a long time or undergoing maintenance, the external circulation cooling water inlet valve and gas inlet valve should be closed. If the ambient temperature is below 5C, the circulating cooling water inside the unit should be drained completely, and the drain plugs on the water pump and external circulating cooling water pipeline should be opened to drain the water. If necessary, an air compressor should be used to blow the pipeline.

　　5、手動盤車至少5圈，同時有手動預供油泵泵油0.01Mpa。

　　5. Manual turning should be done at least 5 times, and there should be a manual pre supply oil pump that pumps oil at 0.01Mpa.

　　四、發電機組故障停機的處理

　　4、 Handling of generator set shutdown due to malfunction

　　1、當發電機組因超速、過電流、逆功率、水溫、油溫高及油壓低故障，引起突然停機時。應關斷氣源，查明故障原因并妥善處理后方可開機。2、當遇有緊急情況，可按下“緊急停車”按鈕，使機組停機。注意:突然緊急停機后，一定要用人力盤車，盤轉曲軸至少5圈，同時用手動預供油泵泵油，待機組水溫、油溫降低后，進行檢查處理，并向有關部門或領導匯報。

　　1. When the generator set suddenly shuts down due to overspeed, overcurrent, reverse power, high water temperature, high oil temperature, and low oil pressure faults. The gas source should be turned off, the cause of the malfunction should be identified and properly handled before starting up. 2. In case of emergency, the "emergency stop" button can be pressed to shut down the unit. Attention: After a sudden emergency stop, it is necessary to manually turn the crankshaft at least 5 times and use a manual pre supply oil pump to pump oil. After the water temperature and oil temperature of the standby group decrease, check and handle it, and report to the relevant department or leader.
