高层建筑中柴油发电机组的选择要求

在高层建筑供电设计中,首先必须明显什么情况下应设置柴油发电机组,我们先从高层建筑的负荷等级谈起:

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:

高层建筑中的消防水泵、防排烟设施、消防电梯、应急照明等消防用电,一类高层建筑应安一级负荷要求供电,二类高层建筑应按二级负荷要求供电。

瓦斯发电机组

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.

一级负荷应由两个电源共电。二级负荷当条件允许时也宜由两个回路供电,特别是属于消防用电的二级负荷,应按二级负荷的两个回路要求供电。由此可见,高层建筑对供电的可靠性要求较高,都要求两个电源供电。因此,考虑设置柴油发电机组的原则如下:

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:

对电网能够提供二个独立电源的高层建筑,按规范已经满足了一、二级负荷的要求,原则上可不设柴油发电机组。但是,对于特别重要的高层建筑(如超高层建筑),其内部含有特别重要负荷,应考虑一电源系统检修或故障时,另一电源系统又发生故障的严重情况,此时一般应设柴油发电机组做应急电源。

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.

对于当地电网只能提供一路电源、或取得第二电源有困难或不经济合理的高层建筑,应设柴油发电机组提供第二电源。此时,柴油发电机组是作为备用电源使用,不仅仅是应急用。

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.
