　　As an important equipment for emergency power supply or distributed energy, the start-up speed of gas generators directly affects the timeliness of power supply, especially in power outage emergency scenarios. The length of start-up time is related to production safety and life security. The start-up time of a gas-fired generator set is not a fixed value, but is influenced by multiple factors such as equipment type, start-up method, and environmental conditions, ranging from a few seconds to a few minutes. Understanding its start-up process and influencing factors can help plan the application scenarios of the unit reasonably.

　　燃?xì)獍l(fā)電機(jī)組的啟動(dòng)流程包含多個(gè)依次銜接的環(huán)節(jié)，各環(huán)節(jié)的耗時(shí)共同構(gòu)成總啟動(dòng)時(shí)間。首先是準(zhǔn)備階段，控制系統(tǒng)接收到啟動(dòng)指令后，需完成自檢（如檢查機(jī)油壓力、水箱水位、燃?xì)鈮毫κ欠裾＃?，這一過(guò)程通常需要 5-10 秒，若檢測(cè)到異常（如機(jī)油不足），系統(tǒng)會(huì)自動(dòng)終止啟動(dòng)并發(fā)出警報(bào)。接著是啟動(dòng)馬達(dá)帶動(dòng)發(fā)動(dòng)機(jī)轉(zhuǎn)動(dòng)，通過(guò)壓縮空氣或電啟動(dòng)方式使曲軸旋轉(zhuǎn)，直至達(dá)到點(diǎn)火所需的轉(zhuǎn)速（通常為 800-1000 轉(zhuǎn) / 分鐘），電啟動(dòng)方式耗時(shí)較短，約 3-5 秒，壓縮空氣啟動(dòng)因需要建立氣壓，耗時(shí)略長(zhǎng)（5-8 秒）。點(diǎn)火成功后，發(fā)動(dòng)機(jī)進(jìn)入怠速暖機(jī)階段，此時(shí)轉(zhuǎn)速維持在 1000-1500 轉(zhuǎn) / 分鐘，待水溫、油溫升至適宜范圍（水溫約 50℃、油溫約 40℃），才能逐步加載至額定轉(zhuǎn)速（1500 轉(zhuǎn) / 分鐘或 3000 轉(zhuǎn) / 分鐘），暖機(jī)時(shí)間根據(jù)環(huán)境溫度差異較大，常溫下約 30-60 秒，低溫環(huán)境（如 - 10℃以下）可能需要 2-3 分鐘，若未充分暖機(jī)就加載，易造成發(fā)動(dòng)機(jī)磨損。最后是并網(wǎng)或供電切換階段，機(jī)組需與電網(wǎng)同步（電壓、頻率、相位匹配），這一過(guò)程約 5-10 秒，整體來(lái)看，常規(guī)燃?xì)獍l(fā)電機(jī)組從啟動(dòng)指令發(fā)出到穩(wěn)定供電，總時(shí)間在 1-5 分鐘范圍內(nèi)。

　　The start-up process of a gas-fired generator set includes multiple sequential links, and the time consumption of each link together constitutes the total start-up time. Firstly, in the preparation stage, after receiving the start command, the control system needs to complete a self check (such as checking whether the oil pressure, water level in the tank, and gas pressure are normal). This process usually takes 5-10 seconds. If an abnormality is detected (such as insufficient oil), the system will automatically terminate the start and issue an alarm. Next, the starter motor drives the engine to rotate, and the crankshaft rotates through compressed air or electric starting until it reaches the required ignition speed (usually 800-1000 revolutions per minute). Electric starting takes less time, about 3-5 seconds, while compressed air starting takes slightly longer (5-8 seconds) due to the need to establish air pressure. After successful ignition, the engine enters the idle warm-up phase, where the speed is maintained at 1000-1500 revolutions per minute. Only when the water temperature and oil temperature reach the appropriate range (about 50 ℃ for water temperature and about 40 ℃ for oil temperature), can it gradually load to the rated speed (1500 rpm or 3000 rpm). The warm-up time varies greatly depending on the ambient temperature, with about 30-60 seconds at room temperature and 2-3 minutes in low temperature environments (such as below -10 ℃). If the engine is not fully warmed up before loading, it may cause engine wear. Finally, during the grid connection or power supply switching phase, the unit needs to synchronize with the grid (voltage, frequency, phase matching), which takes about 5-10 seconds. Overall, the total time for a conventional gas-fired generator set from the start command to stable power supply is within the range of 1-5 minutes.

　　不同類型的燃?xì)獍l(fā)電機(jī)組，啟動(dòng)時(shí)間存在顯著差異。小型便攜式燃?xì)獍l(fā)電機(jī)組（功率 5-50 千瓦）因結(jié)構(gòu)簡(jiǎn)單、部件輕便，啟動(dòng)流程簡(jiǎn)化，從啟動(dòng)到供電通常只需 1-2 分鐘。這類機(jī)組多采用電啟動(dòng)方式，省略復(fù)雜的預(yù)熱環(huán)節(jié)，適合家庭應(yīng)急或小型設(shè)備臨時(shí)供電，但其暖機(jī)不充分可能影響壽命。中型機(jī)組（功率 50-500 千瓦）配置相對(duì)完善，包含必要的預(yù)熱系統(tǒng)，啟動(dòng)時(shí)間通常為 2-3 分鐘，能在保證機(jī)組安全的前提下較快供電，廣泛應(yīng)用于商業(yè)建筑、中小型工廠的應(yīng)急供電。大型燃?xì)獍l(fā)電機(jī)組（功率 500 千瓦以上）因發(fā)動(dòng)機(jī)體積大、部件慣性強(qiáng)，啟動(dòng)流程更復(fù)雜，需經(jīng)過(guò)嚴(yán)格的預(yù)熱、吹掃（排除缸內(nèi)可能存在的可燃?xì)怏w）、同步等步驟，啟動(dòng)時(shí)間往往需要 3-5 分鐘，但其穩(wěn)定性高，適合大型工業(yè)場(chǎng)所或電網(wǎng)調(diào)峰使用。

　　There are significant differences in the start-up time of different types of gas-fired generator sets. Small portable gas generator sets (with a power of 5-50 kW) typically take only 1-2 minutes from start-up to power supply due to their simple structure, lightweight components, and simplified start-up process. These types of units often use electric starting methods, omitting complex preheating steps, making them suitable for household emergency or temporary power supply for small equipment. However, insufficient warm-up may affect their lifespan. Medium sized units (with a power of 50-500 kilowatts) are relatively well-equipped, including necessary preheating systems. The start-up time is usually 2-3 minutes, and they can provide power quickly while ensuring the safety of the unit. They are widely used for emergency power supply in commercial buildings and small and medium-sized factories. Large gas generator sets (with a power of over 500 kilowatts) require strict preheating, purging (to eliminate possible combustible gases in the cylinder), synchronization, and other steps due to their large engine volume, strong component inertia, and more complex start-up process. The start-up time often takes 3-5 minutes, but it has high stability and is suitable for use in large industrial sites or power grid peak shaving.

　　啟動(dòng)方式的選擇直接影響燃?xì)獍l(fā)電機(jī)組的啟動(dòng)速度。電啟動(dòng)是最常見(jiàn)的方式，通過(guò)蓄電池驅(qū)動(dòng)啟動(dòng)馬達(dá)帶動(dòng)發(fā)動(dòng)機(jī)，啟動(dòng)響應(yīng)快（3-5 秒即可帶動(dòng)曲軸轉(zhuǎn)動(dòng)），但受蓄電池電量影響，低溫環(huán)境下若電量不足，可能出現(xiàn)啟動(dòng)失敗，需配備蓄電池保溫裝置或備用電源。壓縮空氣啟動(dòng)則利用高壓空氣（壓力通常為 0.6-0.8MPa）推動(dòng)氣動(dòng)馬達(dá)，適合大型機(jī)組，啟動(dòng)扭矩大，不受低溫影響，但需提前儲(chǔ)備壓縮空氣，充氣過(guò)程會(huì)增加整體啟動(dòng)時(shí)間。全自動(dòng)啟動(dòng)方式（搭配 ATS 自動(dòng)轉(zhuǎn)換開(kāi)關(guān)）能進(jìn)一步縮短響應(yīng)時(shí)間，當(dāng)檢測(cè)到電網(wǎng)斷電后，系統(tǒng)會(huì)在 1-2 秒內(nèi)發(fā)出啟動(dòng)指令，比手動(dòng)啟動(dòng)節(jié)省操作時(shí)間，尤其適合無(wú)人值守的應(yīng)急場(chǎng)景，從斷電到機(jī)組供電的總時(shí)間可控制在 3 分鐘以內(nèi)。

　　The choice of starting method directly affects the starting speed of the gas generator set. Electric starting is the most common method, which uses a battery to drive the starter motor to drive the engine. The starting response is fast (3-5 seconds can drive the crankshaft to rotate), but due to the influence of battery power, if the battery power is insufficient in low-temperature environments, starting failure may occur, and battery insulation devices or backup power sources need to be equipped. Compressed air start-up uses high-pressure air (usually 0.6-0.8MPa) to drive the pneumatic motor, which is suitable for large units with high starting torque and is not affected by low temperatures. However, compressed air needs to be reserved in advance, and the inflation process will increase the overall start-up time. The fully automatic start mode (combined with ATS automatic transfer switch) can further shorten the response time. When a power outage is detected, the system will issue a start command within 1-2 seconds, saving operation time compared to manual start, especially suitable for unmanned emergency scenarios. The total time from power outage to unit power supply can be controlled within 3 minutes.

　　環(huán)境條件對(duì)燃?xì)獍l(fā)電機(jī)組的啟動(dòng)時(shí)間有不可忽視的影響。低溫環(huán)境（低于 0℃）會(huì)導(dǎo)致機(jī)油粘度增加、蓄電池容量下降，發(fā)動(dòng)機(jī)轉(zhuǎn)動(dòng)阻力增大，啟動(dòng)馬達(dá)帶動(dòng)曲軸達(dá)到點(diǎn)火轉(zhuǎn)速的時(shí)間延長(zhǎng)，可能比常溫下增加 50% 以上，此時(shí)需啟用預(yù)熱系統(tǒng)（如缸體加熱器、進(jìn)氣預(yù)熱器），預(yù)熱時(shí)間通常為 1-3 分鐘，雖增加了啟動(dòng)總時(shí)間，但能保證啟動(dòng)成功率。高溫高濕環(huán)境（溫度超過(guò) 35℃、濕度超過(guò) 85%）會(huì)影響燃?xì)馀c空氣的混合比例，可能導(dǎo)致點(diǎn)火延遲或啟動(dòng)后轉(zhuǎn)速波動(dòng)，需通過(guò)調(diào)整空燃比補(bǔ)償，啟動(dòng)時(shí)間會(huì)增加 10%-20%。高海拔地區(qū)（海拔超過(guò) 1000 米）因空氣稀薄，發(fā)動(dòng)機(jī)進(jìn)氣量不足，啟動(dòng)時(shí)可能需要多次嘗試才能成功，啟動(dòng)時(shí)間比平原地區(qū)延長(zhǎng) 20-30 秒，且需對(duì)化油器或燃?xì)鈬娚湎到y(tǒng)進(jìn)行改裝，以適應(yīng)低氣壓環(huán)境。

　　The environmental conditions have an undeniable impact on the start-up time of gas-fired power generation units. Low temperature environment (below 0 ℃) can cause an increase in oil viscosity, a decrease in battery capacity, an increase in engine rotational resistance, and a longer time for the starter motor to drive the crankshaft to ignition speed, which may be more than 50% longer than at room temperature. At this time, preheating systems (such as cylinder block heaters and intake preheaters) need to be activated, and the preheating time is usually 1-3 minutes. Although it increases the total starting time, it can ensure the success rate of starting. High temperature and high humidity environment (temperature exceeding 35 ℃, humidity exceeding 85%) can affect the mixing ratio of gas and air, which may cause ignition delay or speed fluctuation after starting. It is necessary to compensate by adjusting the air-fuel ratio, and the starting time will increase by 10% -20%. In high-altitude areas (over 1000 meters above sea level), due to thin air and insufficient engine intake, multiple attempts may be required to successfully start the engine. The start-up time is 20-30 seconds longer than in plain areas, and the carburetor or gas injection system needs to be modified to adapt to low-pressure environments.

　　維護(hù)狀況良好的燃?xì)獍l(fā)電機(jī)組，啟動(dòng)時(shí)間更穩(wěn)定且偏短。發(fā)動(dòng)機(jī)若長(zhǎng)期未保養(yǎng)，機(jī)油變質(zhì)會(huì)增加摩擦阻力，濾芯堵塞會(huì)導(dǎo)致進(jìn)氣、供油不足，啟動(dòng)時(shí)可能出現(xiàn) “啟動(dòng)困難”（多次嘗試才能成功），使啟動(dòng)時(shí)間延長(zhǎng)甚至翻倍。啟動(dòng)系統(tǒng)部件（如啟動(dòng)馬達(dá)、電磁閥）的磨損，會(huì)導(dǎo)致啟動(dòng)動(dòng)力不足，曲軸轉(zhuǎn)速難以達(dá)到點(diǎn)火要求，需更換部件才能恢復(fù)正常啟動(dòng)速度。相反，定期更換機(jī)油、清理濾芯、檢查啟動(dòng)系統(tǒng)的機(jī)組，各環(huán)節(jié)運(yùn)行順暢，啟動(dòng)時(shí)間能保持在設(shè)計(jì)范圍內(nèi)，減少意外延誤。

　　A well maintained gas generator set has a more stable and shorter start-up time. If the engine is not maintained for a long time, the deterioration of the engine oil will increase frictional resistance, and the blockage of the filter element will lead to insufficient intake and fuel supply. During startup, there may be "difficulty starting" (multiple attempts are required to succeed), which can prolong or even double the startup time. The wear and tear of components in the starting system (such as the starter motor and solenoid valve) can lead to insufficient starting power and difficulty in achieving the required crankshaft speed for ignition. Replacement of these components is necessary to restore normal starting speed. On the contrary, regularly changing the engine oil, cleaning the filter element, and checking the starting system of the unit can ensure smooth operation in all aspects and keep the starting time within the design range, reducing unexpected delays.

　　燃?xì)獍l(fā)電機(jī)組的啟動(dòng)時(shí)間是多種因素共同作用的結(jié)果，常規(guī)情況下從啟動(dòng)到穩(wěn)定供電需 1-5 分鐘，具體時(shí)間需結(jié)合機(jī)組類型、啟動(dòng)方式、環(huán)境條件及維護(hù)狀況綜合判斷。在實(shí)際應(yīng)用中，需根據(jù)場(chǎng)景對(duì)供電及時(shí)性的要求選擇合適的機(jī)組 —— 應(yīng)急供電（如醫(yī)院、數(shù)據(jù)中心）應(yīng)優(yōu)先選擇啟動(dòng)速度快（3 分鐘以內(nèi)）的中型全自動(dòng)機(jī)組；對(duì)啟動(dòng)時(shí)間要求不高的常規(guī)發(fā)電（如養(yǎng)殖場(chǎng)、工廠自備電源），可選擇性價(jià)比更高的普通機(jī)組。同時(shí)，做好機(jī)組的日常維護(hù)與環(huán)境適應(yīng)性改造，能有效保證啟動(dòng)時(shí)間的穩(wěn)定性，確保在需要時(shí)及時(shí)發(fā)揮作用。

　　The start-up time of a gas-fired generator set is the result of multiple factors working together. Under normal circumstances, it takes 1-5 minutes from start-up to stable power supply. The specific time needs to be comprehensively judged based on the type of unit, start-up method, environmental conditions, and maintenance status. In practical applications, suitable units should be selected according to the requirements of power supply timeliness in the scenario - emergency power supply (such as hospitals, data centers) should prioritize medium-sized fully automatic units with fast start-up speed (within 3 minutes); For conventional power generation systems that do not require high start-up time (such as farms or factories with their own power sources), more cost-effective conventional units can be chosen. At the same time, carrying out daily maintenance and environmental adaptability modification of the unit can effectively ensure the stability of the start-up time and ensure timely effectiveness when needed.
