Starting-up at runaway speed condition; 在倒流倒转即飞逸情况下启动;
The dynamic process of load dumping is analyzed and a new mathematical mathematical model to calculate the value of runaway speed is presented. 本文分析了汽轮机甩负荷的动态过程,提出了计算飞升转速的新数学模型,用施给系统小扰动的方法确定飞升转速。
To ensure that the hydraulic turbine runs normally and stably with high efficiency on its working condition, we need to carry a few model-tests concerning the efficiency, cavitation and runaway speed of the hydraulic turbine in different working conditions. 为了保证水轮机能够在其工况内正常、高效、稳定的运行,需要对水轮机在各种工况下的效率、空化、飞逸转速等进行模型试验。
