高层建筑宾馆大楼的变压器装接容量,相当于一个大中型工厂,一般都是几千千伏安,有的达几万千伏安。每月电费高达几十万甚至百万以上,相当多的宾馆属用电大户。在宾馆大楼消耗的电能中,损耗占25～35%,其中一部分是基本损耗(目前难以消除)大部分是由于设备处于非经济运行状态所引起的附加损耗。推行经济运行技术,能在少投资甚至不投资的情况下,减少各类附加损耗,提高电气设备的运行效率,获得显著的节电效果。一、宾馆大楼供电系统附加电能损耗分析宾馆大楼的供电系统和电气设备,常有以下几种附加电能损耗:(一)负荷波动附加电能损耗在宾馆大楼
The transformer installation capacity of a high-rise building hotel building is equivalent to a large and medium-sized factory, which is generally several thousand kVA, and some of them reach tens of thousands of kVA. Monthly electricity bills are as high as several hundred thousand or even more than one million. A considerable number of hotels are large electricity users. In the electrical energy consumed in the hotel building, the loss accounts for 25 to 35%, and part of the basic loss (which is difficult to eliminate at present) is mostly due to the additional loss caused by the non-economic operation of the equipment. The implementation of economic operation technology can reduce various types of additional losses, increase the operating efficiency of electrical equipment, and achieve significant power-saving effects with little or no investment. I. Analysis of additional power consumption of the power supply system of the hotel building The power supply system and electrical equipment of the hotel building often have the following types of additional power consumption: (1) Additional fluctuation of load fluctuations in the hotel building
