柴油发电机组开机步骤如下：
1、拧松喷油泵上的放气螺钉，用燃油手泵排除燃油系统内的空气，同时将调整控制手柄固定在适宜启动转速的油门位置。
2、按下启动按钮，使柴油机启动，如10秒（最多15秒），柴油机仍不能着火启动，则应待1分钟后再作第二次启动，若连续三次仍无法启动则应检查并找出故障原因。
3、柴油机启动后，应密切注意机油压力表读数（正常运转时为2．5—3．5kg/C㎡），如机油压力表不指示，应立即停机检查，并检查电流表有无充电指示。
4、柴油发电机组启动后，空载转速逐渐增加到1000—1200r/min，（注意不得长时间低速运转），进行柴油机的预热过程后，再将转速提高到额定转速。待出水温度达到55℃，机油温度达到45℃时，才允许进入全负荷运转。
5、当发电机组各仪表指示正常时，即可合上负荷开关向负载送电，随着机组负荷的变化，若频率和电压不在规定范围内，应及时调整频率和电压，使其保持额定值，严禁发电机组在低转速情况下带负荷，以免损坏设备。
6、机组投入正常运转后，应随时注意观察水温、油温、油压的变化以及功率表、频率表、电流表、电压表的读数，发现异常应及时处理。
The start-up steps of the diesel generator set are as follows:
1. Loosen the bleed screw on the fuel injection pump, use a fuel hand pump to remove air from the fuel system, and fix the adjustment control handle at the appropriate throttle position for starting speed.
2. Press the start button to start the diesel engine. If the engine still cannot ignite and start after 10 seconds (up to 15 seconds), wait for 1 minute before starting again. If it still cannot start for three consecutive times, check and identify the cause of the fault.
3. After starting the diesel engine, close attention should be paid to the reading on the oil pressure gauge (2.5-3.5 kg/C ㎡ during normal operation). If the oil pressure gauge does not indicate, the engine should be stopped immediately for inspection, and the ammeter should be checked for charging indication.
4. After the diesel generator set is started, the no-load speed gradually increases to 1000-1200r/min (note not to run at low speed for a long time), and after the preheating process of the diesel engine, the speed is increased to the rated speed. Only when the outlet water temperature reaches 55 ℃ and the engine oil temperature reaches 45 ℃, is it allowed to enter full load operation.
5. When the various instruments of the generator set indicate normally, the load switch can be closed to supply power to the load. As the load of the unit changes, if the frequency and voltage are not within the specified range, they should be adjusted in a timely manner to maintain the rated value. It is strictly prohibited for the generator set to carry the load at low speed to avoid damaging the equipment.
6. After the unit is put into normal operation, attention should be paid to the changes in water temperature, oil temperature, oil pressure, as well as the readings of the power meter, frequency meter, ammeter, and voltmeter at all times. Any abnormalities should be promptly dealt with.
