Research On Optimal Scheduling Of Jinsha River Downstream Cascade Based On Irrigation

With the development of China's socialist construction, China's demand for energy is also growing.The traditional fossil energy is unfriendly to environment, it also does not meet the requirements of sustainable development strategy in china. China have many rivers and water resources, hydropower is one of the most clean energy in world. Therefore, developing water resources reasonable has become a priority among priorities for China's energy development. Jinsha River is range first in China's twelve largest hydropower base, has abundant water resources, fall head concentrate and excellent energy index. Generated electricity can provide energy for the southwest region economy development, but also can be connected with the central China power grid, power can also supply to eastern coastal areas and reach the goal of "power transmission from west to east". Currently Jinshan River has totally planed four large-scale hydropower station, respectively is Xiangjiaba, Xiluodu, Baihetan and Wudongde hydropower Station. Xiangjiaba, Xiluodu hydropower station has been put into power generation. The Xiangjiaba Hydropower Station has the function of flood control, power generation, shipping and other functions, but also has the function of irrigation. Xiangjiaba is China's first seat with both for power generation and irrigation.Xiangjiaba irrigation project in the main water supply for the Xiangjiaba Dam irrigation area. Xiangjiaba irrigation area is refers to the Daan district, Zigong city, Le Zhen in Xingwen city, from Xiangjiaba project to the east of the Yangtze River, Chishui River bound; Supplying water resources to Zigong city,Neijiang city and Nongchang city at the same time. The irrigated area involved Yibin City, Sichuan Province, Luzhou City, Zigong, Neijiang City, a total of four city 21 county and Zhaotong City in Shuifu County Yunnan Province.This paper selects Xiangjiaba, Xiluodu Hydropower Station as the research object. analysising the water level process at the object of max generating capacity in condition of Xiangjiaba irrigating respectively in wet season, normal season, drought season and disgussing the influence to the electric power generation. The main research contents are as follows:First, investigate population, livestock, agricultural water scale in irrigated area and analysising the reasonable Xiangjiaba irrigation water requirement and considering the self supply of water resources in the irrigated area. Calculating the the process of water flow meter using north and South main canal.Then, the paper summarized the basic situation of the Xiangjiaba, Xiluodu hydropower station, detailed summarized Xiangjiaba hydropower station and Xiluodu power station operation index. These index are foundations for the back up cascade optimal scheduling modelNext, this paper established Xiangjiaba, Xiluodu cascade generation optimal scheduling model for the goal of the "year" maximum power capacity at the actual situation of the operation of the power station in accordance with the reasonable constraint conditions. Then summarized the optimal solution in use of the merits of different methods. Prepareing for solving optimal scheduling model belowed.On the end, setting Jinsha River Xiangjiaba, Xiluodu Hydropower Station as an example and solving the cascade optimization scheduling model based on the reasonable constraint in use of the Jinsha River historical runoff data. Then analyzing the results, discussing the influence to the maximum power capacity in wet season, normal season and drought season when considering the irrigation.The conclusions has certain scientific significance to the Jinsha River cascade dispatching decision-making...
