This will create a national electricity network for the first time in danish history 这将是丹麦历史上首次建成的一条全国性电力网络。
Rational power network is not particular studied what is rational parameter value about power loss and how is distributed 一个结构合理的电力网络,其线损的合理指标值是多少,分布情况又如何
Only in places unconnected to an electricity grid , such as much of rural africa and rural asia , are solar cells truly commercially viable 太阳能电池仅在电力网络不完善的非洲和亚洲具有真正的商业可行性。
Therefore the fault damages transformer itself , affects the power system network , and brings loss to users 因而,其故障不仅对变压器本身造成损失,同时也会因变压器故障而波及电力网络,给用户造成间接损失。
Leds could , however , have an even greater impact in parts of the developing world that lack mains power and electric lighting altogether 然而,在那些缺少电力网络和照明的发展中国家, led [ 1 ]可能已扮演更加重要的角色。
Moreover , the vehicle does not need to charge the battery pack from the electricity network for keeping its battery soc at a reasonable level 而且,电池也不需要从电力网络中充电就能使电池的荷电状态保持在一个理想的范围。
Firstly , five classes of electrical dissecting methods for paths between sources and flows are presented based on the definition of electrical sources and flows 首先,在定义电气源流的基础上,提出了5类电力网络源流路径电气剖分。
Research on paths between sources and flows becomes pressing and important during the development process of modern electric network 现代电力系统快速发展过程中出现的许多亟待解决的新的难点热点问题使得电力网络源流路径问题的研究变得十分紧迫和重要。
A new method called electrical dissecting method for paths between sources and flows in power network is proposed to satisfy the demands of research 这就要求尽快研究新的方法去解决这些难题。电力网络源流路径电气剖分的思想在一定程度上适应了上述问题研究的需要。
As its individual landform and physiognomy , the activity of thunder in pingbei oilfield has certain speciality , and has influenced seriously the operation of the electric power network 摘要由于地形、地貌独特,坪北油田的雷电活动有著一定的特殊性,并严重影响著电力网络的运行。
