　　(1) Close the air source butterfly valve of the unit, step on the main start switch, press the start button (3-5 seconds), and empty the unit.

　　(2) 打开气源蝶阀，燃气压力最低不小于0.05 MPa，最高不大于0.3MPa。

　　(2) Open the gas source butterfly valve, and ensure that the minimum gas pressure is not less than 0.05 MPa and the maximum is not greater than 0.3 MPa.

　　(3) 踩下脚踏开关，按下启动按钮，发动机启动点火运转。起动电机连续运行不得超过10秒，若三次启动不成功，应及时查明原因后方可再次启动。注意:发动机启动后，要立即释放启动按钮，并踢开脚踏开关，以免损坏启动电机。

　　(3) Step on the foot switch, press the start button, and the engine will start and ignite. The starting motor should not run continuously for more than 10 seconds. If it fails to start three times, the cause should be promptly identified before restarting. Attention: After starting the engine, immediately release the start button and kick off the foot switch to avoid damaging the starter motor.

　　(4) 发动机启动后，使其运转在600r/min~800r/min总速运行，进行暖机，同时观察各仪表指示是否正常。

　　(4) After starting the engine, run it at a total speed of 600r/min~800r/min, warm up the engine, and observe whether the instrument readings are normal.

　　(5) 观察各缸缸温、排温是否正常。焦炉煤气机组:当个别缸温超过300C时，迅速减小相应缸步进电机控制器的步数，当缸温低于150C;排温低于300C时增加相应缸步进电机控制器的步数。

　　(5) Observe whether the cylinder temperature and exhaust temperature of each cylinder are normal. Coke oven gas unit: When the temperature of individual cylinders exceeds 300C, quickly reduce the number of steps of the corresponding cylinder stepper motor controller. When the cylinder temperature is below 150C; When the exhaust temperature is below 300C, increase the number of steps of the corresponding cylinder stepper motor controller.

　　(6) 将怠速/额定转换开关置于“额定”位置，使发电机组空载运行，待发动机油温、水温升至40C后，方可并网运行。

　　(6) Place the idle/rated switch in the "rated" position to allow the generator set to run without load. Only when the engine oil and water temperatures rise to 40C, can it be connected to the grid for operation.

　　(7) 调整电压整定电位器使空载电压为400V左右，调整转速微调电位器使频率为50HZ。

　　2、机组并网运行

　　2. Unit grid connected operation

　　(1)、待发电机组运行正常后，先将发电机组的电压、频率调整至与电网大致相同时，再把同步测量开关置于“井车”位置，观察同步表;

　　(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)、调整控制屏上的转速微调电位器，使之与电网频率相同，即同步表频率差指示“Hz”指针处在中间略高位置:

　　(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) 、调节电压整定电位器，使机组电压与电网电压相同，即同步表电压差指示“V”指在中间位置。

　　(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.

　　注意:反复调整发电机组，并观察同步表相位差指示“S”指针，使其缓慢顺时针旋转。当指针旋转接近垂直向上位置时，左手按下主开关合闸按钮，右手断开同步测量开关，主开关合闸并网发电。左手调整电压整定电位器，将功率因数控制在滞后0.9-0.8之间，右手缓慢调整转速微调电位器给机组加载。调整功率到合适位置(新机为60%Pe)最后将功率因数调整在0.8-0.9之间。

　　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)发电机并网运行中，应注意观察电器仪表及微机柜主控画面各项参数的指示状况，并根据技术要求，及时修正各项参数。

　　(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)机组正常运行中，每15分钟作一次巡回检查，观察油温、水温、机油压力、压差、燃气压力及水位、油位，每两小时对机组参数作一次记录。

　　(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.
