中文摘要:抽水蓄能电站的安全稳定运行与水泵水轮机反S特性直接相关。在电站甩负荷工况下,时有发生调速器事故,导致水泵水轮机导叶拒动,使机组进入飞逸工况。而由于水泵水轮机的反S特性会使得机组参数不能像常规水轮机一样快速收敛,甚至出现振荡的现象,导致事故进一步扩大。针对布置有下游调压室的抽水蓄能电站,采用线性化处理方法获得了水泵水轮机反S特性曲线的传递函数,并建立了流道—水轮机—发电机耦合的常微分数学模型,并进一步推导了水泵水轮机飞逸工况稳定性的判别条件。结果表明飞逸振荡的现象由多种因素共同决定,其中水泵水轮机飞逸点的曲线斜率为关键因素。利用已建立的物理模型平台,对这些影响因素进行了分析,并验证了所得的理论分析结论。

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
