The gas generator set is a new type of new energy generator that uses liquefied gas, natural gas and other combustible gases as the combustor and replaces gasoline and diesel as the engine power. For new users, what are the startup methods and steps for gas generator sets?

燃气发电机组可以手动操作，合上预供油开关，启动电动预供油泵（或扳动手摇机油泵）。待主油道压力达到100kPa后，按下起动按钮，机组起动后，立即释放起动按钮并断开起动开关。机组每次起动时间为5s，若连续起动三次不成功，应检查原因，排除故障后再起动。发动机运行后，可按下“翻页”按钮，通过液晶显示屏检查发动机运行中各项技术参数的变化。起动成功后应怠速暖机，当机油温、水温达到40℃以上，方可加速、加载。

The gas generator set can be operated manually. Close the pre oil supply switch and start the electric pre oil supply pump (or pull the hand oil pump). When the pressure of the main oil passage reaches 100KPA, press the start button. After the unit starts, release the start button and disconnect the start switch immediately. The unit shall be started for 5S each time. If the unit fails to be started for three consecutive times, the cause shall be checked and the unit shall be started after troubleshooting. After the engine is running, press the "page turning" button to check the changes of various technical parameters during engine operation through the LCD. After successful startup, the engine shall be warmed up at idle speed. When the engine oil temperature and water temperature reach above 40 ℃, the engine can be accelerated and loaded.

按动或调节控制屏上加减速旋钮调整机组的频率，使之略高于额定频率。调整控制屏上的电压调节器的微调旋钮，使交流电压表在400V位置，合上主开关，机组便向负载供电。机组带载运行后，若电压、频率偏离了额定值，分别调节转速旋钮和电压整定电位器，使电压频率达到额定值。

Press or adjust the acceleration and deceleration knob on the control panel to adjust the frequency of the unit to slightly higher than the rated frequency. Adjust the fine-tuning knob of the voltage regulator on the control panel so that the AC voltmeter is at the 400V position, close the main switch, and the unit will supply power to the load. After the unit operates under load, if the voltage and frequency deviate from the rated value, adjust the speed knob and the voltage setting potentiometer respectively to make the voltage and frequency reach the rated value.

燃气发电机组还可以自动操作，对于应急自动燃气发电机组来说，发电机组应该一直处于准启动状态（定期自动预润滑、保持油温水温），在接到自动控制系统的启动命令后（失去市电、总体功率不足等），机组会自动启动，并且在达到额定状态后自动合闸带载。

The gas-fired generator set can also be operated automatically. For the emergency automatic gas-fired generator set, the generator set should always be in the quasi start state (regular automatic pre lubrication, maintaining oil and water temperature). After receiving the start command from the automatic control system (loss of mains power, insufficient overall power rate, etc.), the unit will start automatically, and will automatically switch on with load after reaching the rated state.

燃气发电机组的停机和启动一样可以在机旁、控制屏处操作。发动机的停机操作一般在主开关已经分闸后进行。无论在机旁、监控室还是自动进行操作，基本的过程都是一样的。正常停机应逐步卸去负载并主开关分闸后，将转速选择开关置“怠速”位，天然气发动机机转速至1500r/min。按照天然气发动机使用维护说明书的要求对机组进行冷机后，将“停机”旋钮旋至停机位置，使发动机停止工作。停机后将电气开关全部置停机位置上，各调节旋钮亦复原到停机的相应位置，以便下次起动。

The shutdown and startup of the gas generator set can be operated at the machine side and the control panel. The engine shutdown operation is generally carried out after the main switch has been opened. The basic process is the same whether it is operated at the machine side, in the monitoring room or automatically. After the normal shutdown, the load shall be gradually removed and the main switch is opened, the speed selection switch shall be set to the "idle" position, and the natural gas engine speed shall be 1500r/min. After cooling the unit in accordance with the requirements of the operation and maintenance manual of natural gas engine, turn the "stop" knob to the stop position to stop the engine. After the shutdown, set all the electrical switches to the shutdown position, and return all the adjustment knobs to the corresponding shutdown position for the next start.

由此看来，燃气发电机组的开机操作可以在机旁进行，也可以在控制屏端进行。目前启动机组使用多是自动启动，机组的智能化的提高使机组自动启动比手动启动的效率更高。

From this point of view, the start-up operation of the gas generator set can be carried out at the machine side or at the control panel side. At present, most of the start-up units are automatically started. The improvement of the intelligence of the unit makes the efficiency of the automatic start-up of the unit higher than that of the manual start-up.
