Voltage stability analysis based on short circuit capacity

第30届中国控制与决策会议

作者： Cheng Xueting Wang Tan liu xinyuan Pi Jun Meng Tao Wang Zhipeng State Grid Shanxi Electric Power Research Institute State Grid Shanxi Electric Power Company

Voltage stability has been seriously affected in many countries, and the problem of voltage stability has become increasingly prominent with the gradual expansion of interconnection scale and the rapid growth of power demand. Aiming at the problem of voltage stability, taking the Shanxi power grid as an example, the paper demonstrates the short-circuit capacity and voltage stability of the bus.

学术思想和学术研究的进步离不开学术传承。学术传承应是在全面系统回顾前辈研究成果的基础上,提炼出成果中的特质,即展现独特的学术思路和学术精神,以启示后学。邹振环在《20世纪中国翻译史学史》后记中曾谈到当今青年学者对前人研究成果有意无意的忽略和无视令人担忧,他认为“学者的使命无非就是‘因’和‘创’两个方面,所谓‘因’就是承继,‘创’自然是创新”,而且这种创新是基于承继的批判性创新(2017)。无因何来创?倘若没有学术承继,一来可能造成研究的重复。不了解前人已经或隐或明总结出来的经验,不明白前人是否曾经针对某一问题做过什么研究,已经做到了什么程度,就无法在实践中践行并提升前人的经验,也无法在整个研究框架中合理定位,依据前人的研究继续探寻与发展;二来可能造成研究的停滞。某一思想或传统一旦无人传承,就会失去活力,其发展就会受阻。

赛珍珠（1892—1973）是美国著名女作家。她一生的著作中有一半以上的文字同描写中国、介绍中国有关。赛珍珠所以能如此了解熟悉中国人民的生活并进行成功的描述，完全得益于她长期生活在江苏的经历。她在中国度过了将近40年，而这40年是她一生中难以忘怀的重要岁月。她曾充满激情地说：“如果我不为中国人说话，我就不忠实于自己，因为中国人的生活多年来并将永远是我生活的一部分。”为此，她称中国为她的“第二祖国”。

离心压气机进口常采用弯管导流进气,弯管中的二次流动会导致压气机进口气流出现畸变,影响压气机的气动性能。针对这一问题,通过数值仿真与台架试验相结合的方式,研究弯管对离心压气机特性的影响规律及产生机理。在此基础上提出在弯管内增加导流肋片的改进方法,并进行数值仿真与试验验证。研究结果表明:在压气机进口增加弯管后,压比和效率特性都发生了一定程度的恶化,在大流量工况时,性能的下降尤其显著;采用内部布置导流肋片的弯管结构,能够进一步规范弯管内部气流的流动特征,改善压气机进口流动状态,使流动变得相对均匀,从而使性能得到全方位的提升。
