在高層建筑供電設計中，首先必須明顯什么情況下應設置柴油發(fā)電機組，我們先從高層建筑的負荷等級談起：

In the power supply design of high-rise building, it is necessary to set up diesel generating set obviously. Under the circumstances, we should start with the loading level of the high-rise building:

高層建筑中的消防水泵、防排煙設施、消防電梯、應急照明等消防用電，一類(lèi)高層建筑應安一級負荷要求供電，二類(lèi)高層建筑應按二級負荷要求供電。

Fire fighting pumps, smoke control facilities, fire elevators and emergency lighting in high-rise buildings, such as a class of high-rise buildings should be required to supply power at the first level, and two types of high-rise buildings should be powered by two level load requirements.

一級負荷應由兩個(gè)電源共電。二級負荷當條件允許時(shí)也宜由兩個(gè)回路供電，特別是屬于消防用電的二級負荷，應按二級負荷的兩個(gè)回路要求供電。由此可見(jiàn)，高層建筑對供電的可靠性要求較高，都要求兩個(gè)電源供電。因此，考慮設置柴油發(fā)電機組的原則如下：

The first load shall be supplied by two power supplies. Two stage load, when conditions permit, should also be supplied by two circuits, especially belonging to the two stage load of fire fighting electricity, and the power supply should be supplied according to the two circuit requirements of the two stage load. Thus, the high power supply of high-rise building reliability requirements, require two power supply. Therefore, the principle of setting up diesel generating set is as follows:

對電網(wǎng)能夠提供二個(gè)獨立電源的高層建筑，按規范已經(jīng)滿(mǎn)足了一、二級負荷的要求，原則上可不設柴油發(fā)電機組。但是，對于特別重要的高層建筑(如超高層建筑)，其內部含有特別重要負荷，應考慮一電源系統檢修或故障時(shí)，另一電源系統又發(fā)生故障的嚴重情況，此時(shí)一般應設柴油發(fā)電機組做應急電源。

For the power grid to provide two independent power supply of high-rise buildings, according to specifications, has met the requirements of the one or two level load, in principle, no diesel generator sets. However, it is important for the high-rise buildings (such as high-rise building), which contains the special important load, should be considered a fault or maintenance of power system, power system and other serious fault occurs, the general should set diesel generator for emergency power supply.

對于當地電網(wǎng)只能提供一路電源、或取得第二電源有困難或不經(jīng)濟合理的高層建筑，應設柴油發(fā)電機組提供第二電源。此時(shí)，柴油發(fā)電機組是作為備用電源使用，不僅僅是應急用。

For the local power grid can only provide a power supply, or access to second power supply difficult or uneconomical and reasonable high-rise buildings, diesel generator sets should be provided to provide second power supply. At this point, diesel generators are used as backup power sources, not just for emergency use.
