　　(3) 踩下腳踏開關，按下啟動按鈕，發(fā)動機啟動點火運轉。起動電機連續(xù)運行不得超過10秒，若三次啟動不成功，應及時查明原因后方可再次啟動。注意:發(fā)動機啟動后，要立即釋放啟動按鈕，并踢開腳踏開關，以免損壞啟動電機。

　　(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) 發(fā)動機啟動后，使其運轉在600r/min~800r/min總速運行，進行暖機，同時觀察各儀表指示是否正常。

　　(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) 觀察各缸缸溫、排溫是否正常。焦爐煤氣機組:當個別缸溫超過300C時，迅速減小相應缸步進電機控制器的步數(shù)，當缸溫低于150C;排溫低于300C時增加相應缸步進電機控制器的步數(shù)。

　　(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) 將怠速/額定轉換開關置于“額定”位置，使發(fā)電機組空載運行，待發(fā)動機油溫、水溫升至40C后，方可并網(wǎng)運行。

　　(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) 調整電壓整定電位器使空載電壓為400V左右，調整轉速微調電位器使頻率為50HZ。

　　2、機組并網(wǎng)運行

　　2. Unit grid connected operation

　　(1)、待發(fā)電機組運行正常后，先將發(fā)電機組的電壓、頻率調整至與電網(wǎng)大致相同時，再把同步測量開關置于“井車”位置，觀察同步表;

　　(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)、調整控制屏上的轉速微調電位器，使之與電網(wǎng)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(jié)電壓整定電位器，使機組電壓與電網(wǎng)電壓相同，即同步表電壓差指示“V”指在中間位置。

　　(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:反復調整發(fā)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(wǎng)發(fā)電。左手調整電壓整定電位器，將功率因數(shù)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(shù)調整在0.8-0.9之間。

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

　　(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(shù)作一次記錄。

　　(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.
