| | Four Problems concerning the development of the tidal Power are discussed in this Paper: 1.Tidal Power and its relation to energy development 2.Technical features of tidal power 3.Economic analysis of tidal Power 4.Perspective of developing tidal power in China The author here proposes the method of Internal Rate of Return for analyzing the economic benefits of multi-purpose tidal power project because this method is specially suitable nuder this condition. | | 本文阐述了有关潮汐发电方面的四个问题,即:能源开发与潮汐发电;潮汐发电的技术特征;潮汐发电的经济分析;我国开发潮汐电站的前途。作者特别推荐了采用“总体工程综合利用内部回收率法”来作潮汐电站的经济分析,是符合潮汐电站的具体特点的。 | | 文摘来源 | | The relevant shortcoming of tidal power generation appears on that it couldn't be operated continuously to deliver power energy.This can be overcomed currently by taking the following projects: (1)To operate the tidal power station incorporated with other types of power station to meet the load demaned. (2)To regulate the using time of consumers in phase with the power output from the tidal power station. (3)To adopt double basin-high and low-project. However,all of the above mentioned projects result in no... | | 潮汐发电较大的缺点是间断性发电。现有解决办法是:与其它电站互补发电;调节用电负荷时间;电站用高低双库开发方式。但均有缺点,尤其是高低库方式,库容利用率及发电量均较单库开发方式减半,不经济。本文提出采用新的大、小库开发方式,即在平潮前后,大库中断发电时,由预留的小库发电补偿。其优点是;司做到连续不断发电;发电量较单库开发方式为多;可调峰、调相;且可抽水增加发电量;照常司发挥工程综合利用效用。但水工工程量、投资与高、低库方式一样,较单库方式为多这种大、小库开发方式对河口型、港湾型潮汐电站均司适用。 | | 文摘来源 | | The system of engineering projects of water transfer from Yangtze River to North Plain of Jiangsu Province ( including the gravity and pumping flow ) is a system of multipurpose utilization of water resources.The projects of the system were constructed at beginning of 1961, then successively completed within 17 years. Now, this system includes 14 large or middle size pumping stations with total installed capacity of 115 thousand kW and 95 thousand hp. The capacity of diversion works for gravity flow channel... | | 江苏省江水北调工程是一项从长江引水(包括自引和抽引江水)结合抽排涝水的综合利用工程。该项工程1961年开始兴建,先后建成了大中型抽水站14座,总装机11.5万千瓦及9.5万马力,抽引和自引能力都已达到400米~3/秒。江苏省江水北调工程的初步建成,为淮北大面积的农田改制,里下河、白马湖地区排涝降渍,发展航运,解决工业和城市用水等创造了较好条件。 江苏省江水北调工程的特点是建设的周期很长,建成一项投产一项逐步收益,工程综合利用,既有灌溉效益,亦有排涝、航运和城市、工业供水的效益。本文用水利经济计算的一般原理,就工程的投资、年费用和工程效益作了工程的综合经济效益分析。由于工程项目多,涉及的范围广、周期长,我们组织了一定力量,作了较长期的调查研究。 效益分析采用了静态和动态两种分析方法,动态方法按年息7%,贴现到1980年现值。两种分析方法都说明了该项工程的综合效益是很显著的。本文亦探讨了分项效益的分析方法。 | | 文摘来源 | |   | | << 更多相关文摘 |
