This paper also analyzed the effect of change of passage vortex structure on loss and poillt out that all of the boundary condition which will make passage vortex stale is beneflt to decreaJse secondary loss.
In the paper, a detailed study on the reliability of power generation in Shanghai electric power network, by means of an analysis on loss of load probability (LOLP), is given and the suggestions for improvement of the reliability are also made.
应用电力不足概率(Loss of Load Probability, LOLP)对上海电网的发电可靠性作了较详细的分析,并提出了提高上海电网发电可靠性的建议.
Impact of the admission discipline, variation and correlation coefficients of inter-arrival times distribution, and variation of service times distribution on loss probability is analyzed numerically.
This paper, based on the dynamic experiments in the laboratory simulation model, gives a theoretical analysis on loss-of-excitation protection for large hydroelectric generators. The basic characteristics of the machine during loss of-excitation and other special operating conditions are derived. The required boundary of operating region of loss-of-excitation protection and the locus of measured impedance of theemachin under various special operating conditions on the com...
By means of a lot of experiment, this work deals with the calculation on total efficiency, slope efficiency and magnification, and also with analysis on loss, resonator length and a combination of 2 crystal Nd~(3+): YAG laser with different curved end faces.
Guanting Reservoir, which is a multipurpose hydro-project mainly used for flood-control and water supply to Beijing, is located on the Yongding River. This river and its tributaries Yang River and Sanggan River are sediment-laden rivers. The sediment yield of the gullied-hilly loess area amounts to 10 kt/km2 or more. The yearly average sediment load at Guanting is 70×106 tons.The storage capacity of the reservoir is 2.27 × 109m3, which consists of two parts-----40% in the main stream and 60%in its tri...
