The under - excitation operation of power generators is difficult to carry out in guangdong power grid due to some misunderstanding on it 当前,在广东电网开展发电机进相运行工作中一些人对进相运行的机理不太清楚,认识上存在误区。
Oil firms , carmakers , power generators , nervous of being outmanoeuvred , are jacking up their investments in renewables and biofuels 源于对战略失策的忧虑,石油公司、汽车制造商和电力供应商也开始增加对可再生能源和生物燃料的投资。
Professor elliott believes that the future of energy lies in 6 multiple , small - scale power generators which use non - polluting , renewable energy 埃利奥特教授认为,能源的未来在于多样化、小尺寸的发电机,利用的是无污染的、可再生能源。
As of today , wind - powered generators have been deployed at eight automatic weather stations at lantau and in islands near the airport at chek lap kok 直至现时为止,天文台已为八个位于大屿山及赤立角机场附近小岛上的自动气象站设置风力发电机。

Next , the control technique and arithmetic of doubly - fed vscf wind power generator are also studied in detail , including some of author ' s sights 其次,对变速恒频双馈风能发电的控制技术及其控制算法进行了详尽的研究,其中不乏有作者自己独到的见解。
Inefficient power generators resulted in slow sublight and hyperdrive performance , weak shielding , reduced firepower and frequent surges within the computer systems 低效的能量反应堆使它的亚光速和超光速表现不好,护盾脆弱,火力不强,计算机系统时常冒泡。
However , the control technology of the doubly - fed vscf wind power generator system is rather complicated , some of difficulties and emphases should be perfected in the future 由于本课题的复杂性及其综合性决定了其难度较高,有些难点、重点还需进一步研究完善。
The observatory added another wind - powered generator at yi tung shan , lantau , in february 2001 , making a total of four for its network of automatic weather stations 今年二月,天文台在大屿山二东山上添置了一部风力发电机,使全港装有风力发电机的自动气象站增至四个。
