Big work 16 autumn water conservancy and hydropower planning major operations and requirements answer（大工16秋《水利水能规划》大作业及要求答案） Big work 16 autumn water conservancy and hydropower planning major operations and requirements answer Job content Title: time series method for calculating favorable reservoir capacity Learning center: Major: Year: Spring / autumn Student number: Student： Tutor: 1 basic knowledge 1.1 regulation of reservoir profit Except for non regulated water conservancy and hydropower projects that can only supply natural runoff water, all of them can adjust the storage capacity to a certain extent. The relation between regulation performance and reservoir capacity: the longer the cycle, the better the regulation performance and the larger the storage capacity. 1, according to the adjustment cycle points: (1) daily regulation: the regulation period of daily regulation is one day and four days. That is to say, the daily water demand of reservoir will be adjusted by the daily water demand of the water sector. Daily variation of power load. (2) weekly adjustment: the regulation cycle of the week adjustment is one week, and the inflow runoff which is not changed within a week is adjusted according to the water demand process of the water sector. The weekly variation of power consumption in a period of time. (3) annual adjustment: the annual runoff of inland rivers has changed greatly, and the water supply during the rainy season and the dry season is very different. The task of regulating the annual runoff is to store and increase the surplus water during the flood season in accordance with the annual domestic water demand process in the water sector, so as to increase the water supply during the water shortage period, and the regulation cycle is less than one year. According to the variation of the abundance and drought in the runoff, the regulation of the abundance and deficiency of the seedlings was carried out. (4) adjustment over many years: the task of re
