常用柴油发电机组容量的估算按机组长期持续运行输出功率满足全工程大计算负荷进行选择,根据我国标准GB1105.1-1987《内燃机台架性能试验方法、标准环境工况及功率、燃油消耗和机油消耗的标定》的规定,在标准环境(大气压=100kPa,相对温度=30%,环境温度=298K或25℃,中冷器冷却介质进口温度=298K或25℃。)条

    常用柴油发电机组容量的估算按机组长期持续运行输出功率满足全工程大计算负荷进行选择,根据我国标准GB1105.1-1987《内燃机台架性能试验方法、标准环境工况及功率、燃油消耗和机油消耗的标定》的规定,在标准环境(大气压=100kPa,相对温度=30%,环境温度=298K或25℃,中冷器冷却介质进口温度=298K或25℃。)条件下,柴油机允许连续运行15min的标定功率。而当环境湿度、海拔高度过高时,空气密度则降低,机组运行时燃烧所需氧气的供应量减少,机组的输出功率应作相应下调。换言之,选用的机组功率要比负载的功率值高,即当机组在非标准状况下工作时,应对柴油机进行功率校正。
在常规环境下柴油发电机组持续运行的输出功率,一般为标定功率的0.9倍。若机组容量选择得过小,则无法带动全部负载或者在启动大功率负载时导致突然停机的现象;若机组容量选择得过大,则投资及维修成本高,造成资源浪费。而且根据柴油机的特性,当其长期在小负荷工作时,将造成发动机活塞环、喷油嘴等处积炭严重,汽缸磨损加剧等损坏机组的不良后果。
       柴油发电机组在工作过程中,对阻性负载如灯泡、电炉和烤箱等中小型家用电器,感性负载如机床、水泵等大型用电设备,其中阻性负载的特性是电阻基本保持不变,但电流随电压按比例下降,因此对于不同负载的用电设备,要对柴油发电机组的容量就需要重新计算。

The estimation of the capacity of commonly used diesel generator sets is selected based on the long-term continuous operation output power of the unit to meet the large calculation load of the entire project. According to the Chinese standard GB1105.1-1987 "Test Methods for Internal Combustion Engine Bench Performance, Standard Environmental Conditions and Calibration of Power, Fuel Consumption and Engine Oil Consumption", under standard environmental conditions (atmospheric pressure=100kPa, relative temperature=30%, ambient temperature=298K or 25 ℃, inlet temperature of intercooler cooling medium=298K or 25 ℃), the diesel engine is allowed to operate continuously for 15 minutes at the calibrated power. When the environmental humidity and altitude are too high, the air density decreases, and the supply of oxygen required for combustion during unit operation decreases. The output power of the unit should be correspondingly reduced. In other words, the selected power of the unit should be higher than the power value of the load, that is, when the unit operates under non-standard conditions, the diesel engine should be calibrated for power.

The output power of a diesel generator set operating continuously in a conventional environment is generally 0.9 times the rated power. If the capacity of the unit is selected too small, it will not be able to drive all loads or cause sudden shutdown when starting high-power loads; If the capacity of the unit is chosen too large, the investment and maintenance costs will be high, resulting in resource waste. Moreover, according to the characteristics of diesel engines, when they operate at low loads for a long time, it will cause serious carbon deposits in the engine piston rings, fuel injectors, and other areas, as well as increased cylinder wear and other adverse consequences that can damage the unit.

During the operation of diesel generator sets, for resistive loads such as light bulbs, electric furnaces, and ovens, as well as inductive loads such as machine tools, water pumps, and other large electrical equipment, the characteristic of resistive loads is that the resistance remains basically unchanged, but the current decreases proportionally with voltage. Therefore, for electrical equipment with different loads, the capacity of diesel generator sets needs to be recalculated.

Yangzhou Haihong Electromechanical Equipment Co., Ltd. is a professional generator manufacturer specializing in diesel generator sets, silent generator sets, mobile generator sets, and diesel generator sets with the same brand and configuration. The prices of the produced generator sets are discounted among manufacturers of the same brand and configuration.
