信息摘要:

常用柴油發(fā)電機組容量的估算按機組長期持續(xù)運行輸出功率滿足全工程大計算負荷進行選擇,根據(jù)我國標準GB1105.1-1987《內(nèi)燃機臺架性能試驗方法、標準環(huán)境工況及功率、燃油消耗和機油消耗的標定》的規(guī)定,在標準環(huán)境(大氣壓=100kPa,相對溫度=30%,環(huán)境溫度=298K或25℃,中冷器冷卻介質進口溫度=298K或25℃。)條

    常用柴油發(fā)電機組容量的估算按機組長期持續(xù)運行輸出功率滿足全工程大計算負荷進行選擇,根據(jù)我國標準GB1105.1-1987《內(nèi)燃機臺架性能試驗方法、標準環(huán)境工況及功率、燃油消耗和機油消耗的標定》的規(guī)定,在標準環(huán)境(大氣壓=100kPa,相對溫度=30%,環(huán)境溫度=298K或25℃,中冷器冷卻介質進口溫度=298K或25℃。)條件下,柴油機允許連續(xù)運行15min的標定功率。而當環(huán)境濕度、海拔高度過高時,空氣密度則降低,機組運行時燃燒所需氧氣的供應量減少,機組的輸出功率應作相應下調。換言之,選用的機組功率要比負載的功率值高,即當機組在非標準狀況下工作時,應對柴油機進行功率校正。
在常規(guī)環(huán)境下柴油發(fā)電機組持續(xù)運行的輸出功率,一般為標定功率的0.9倍。若機組容量選擇得過小,則無法帶動全部負載或者在啟動大功率負載時導致突然停機的現(xiàn)象;若機組容量選擇得過大,則投資及維修成本高,造成資源浪費。而且根據(jù)柴油機的特性,當其長期在小負荷工作時,將造成發(fā)動機活塞環(huán)、噴油嘴等處積炭嚴重,汽缸磨損加劇等損壞機組的不良后果。
       柴油發(fā)電機組在工作過程中,對阻性負載如燈泡、電爐和烤箱等中小型家用電器,感性負載如機床、水泵等大型用電設備,其中阻性負載的特性是電阻基本保持不變,但電流隨電壓按比例下降,因此對于不同負載的用電設備,要對柴油發(fā)電機組的容量就需要重新計算。

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.
